Mist Systems gives VMware NSX SD-WAN a boost

Arista Networks and VMware, both recent entrants in campus and branch office networking, have made significant moves to add cloud-based Wi-Fi management and analytics to their respective software portfolios.

VMware launched this week interoperability between its NSX SD-WAN and Mist Systems’ machine learning engine for maintaining Wi-Fi performance. Meanwhile, Arista acquired Mojo Networks for the startup’s analytics, which it calls Cognitive WiFi.

Arista’s purchase of Mojo shows the former vendor taking control over its Wi-Fi offering, rather than depend solely on its current deal to offer Aruba wireless products from Hewlett Packard Enterprise, said Bill Menezes, an analyst at Gartner. “[They’re] going to have much more input and control over the pace of tech development.”

The VMware-Mist collaboration, on the other hand, reflects an industry trend of connecting the wireless access layer in remote offices to an SD-WAN product, Menezes said.

“That’s something that most of the major vendors are looking at in one way or another,” he said. “Some of them, like Cisco and Aruba, are developing that capability in-house.”

Mist is providing interoperability between its products and NSX SD-WAN through open APIs. As a result, the combined products deliver to IT administrators “end-to-end visibility and insight into users, application and network performance for LAN and WAN,” the companies said in a statement. Other features include trend detection and recommendations to avoid problems, and event correlation and anomaly detection for fault isolation and remediation.

Mist combines big data and machine learning to track user behavior on Wi-Fi and ensure network performance. The company’s machine learning engine will help NSX SD-WAN analytics by gathering more than 100 different user states from access points (APs).

Metrics gathered by Mist technology include the time it takes an AP to connect to devices and the number of failed attempts. The system can also collect roaming data, such as when a mobile device switches APs to take advantage of a stronger signal or leaves an AP that’s dropping too much data.

Mist will also add to NSX SD-WAN anomaly detection for APs, mobile devices, operating systems and applications connecting to Wi-Fi. Mist and VMware will sell their products separately through joint channel partners.

In 2017, VMware entered the market for branch-office networking with the acquisition of software-defined WAN vendor VeloCloud. In May, VMware extended its virtual networking software, NSX, to remote offices through integration with VeloCloud, which the company renamed NSX SD-WAN. Combining the technologies made it possible for VMware customers to use NSX for policy-based network management across the data center and branch.

Arista acquires Mojo

The VMware-Mist collaboration came nearly a week after Arista said it would acquire Mojo for its cloud-based software focused on network analytics and management. The acquisition, which Arista expects to close by the end of September, is the company’s first. Arista did not release financial details.

Arista announced the Mojo acquisition roughly three months after introducing its first switches for the campus LAN. Available in the fall, the 7300X3 and 7050X3 spline switches are 10/25/40/50/100 Gigabit Ethernet gear equipped with telemetry and monitoring features designed to help network operators  diagnose performance problems.

Arista acquired Mojo for its machine learning and big data platform. The Cognitive WiFi system tracks more than 300 key performance indicators, Gartner said in its latest Magic Quadrant for the Wired and Wireless LAN Access Infrastructure. The research firm listed Mist and Mojo in the visionary quadrant of the report.

As a campus network supplier, Arista needed more than just technology for the wired LAN, Arista CEO Jayshree Ullal told financial analysts during a recent conference call. That’s because a growing number of Arista customers are turning to Wi-Fi as it approaches multigigabit speeds.

“What we bought Mojo for was their Wi-Fi, their Cognitive WiFi, and the software capabilities associated with the access points [Mojo provides],” Ullal told analysts, according to a transcript on the financial site Seeking Alpha.

Arista plans to  merge Mojo technology with its CloudVision network management software that combines cloud computing, big data and machine learning. The product collects and archives network state and runs a suite of applications against the data to provide visibility, automate the deployment of network components, and analyze and report on incidents.

Kontron heeds carrier demand for software, buys Inocybe

Kontron has acquired Inocybe Technologies, adding open source networking software to the German hardware maker’s portfolio of computing systems for the telco industry.

Kontron, which announced the acquisition this week, purchased Inocybe’s Open Networking Platform as telcos increasingly favor buying software separate from hardware. Kontron is a midsize supplier of white box systems to communications service providers (CSPs) and cable companies.

CSPs are replacing specialized hardware with more flexible software-centric networking, forcing companies like Kontron and Radisys, which recently sold itself to Reliance Industries, to reinvent themselves, said Lee Doyle, principal analyst at Doyle Research, based in Wellesley, Mass.

“This is part of Kontron’s efforts to move in a more software direction — Radisys has done this as well — and to a more service-oriented model, in this case, based on open source,” Doyle said.

Inocybe, on the other hand, is a small startup that could take advantage of the resources of a midsize telecom supplier, mainly since the market for open source software is still in its infancy within the telecom industry, Doyle said.

While Kontron did not release financial details, the price for Inocybe ranged from $5 million to $10 million, said John Zannos, previously the chief revenue officer of Inocybe and now a general manager of its technology within Kontron. The manufacturer plans to offer Inocybe’s Open Networking Platform as a stand-alone product while also providing hardware specially designed to run the platform.

Inocybe’s business

Inocybe’s business model is similar to that of Red Hat, which sells its version of open source Linux and generates revenue from support and services on the server operating system. Under Kontron, Inocybe plans to continue developing commercial versions of all the networking software built under the Linux Foundation.

Open source is free, but making it work isn’t.
Lee Doyleprincipal analyst, Doyle Research

The Open Networking Platform includes parts of the Open Network Automation Platform (ONAP), the OpenDaylight software-defined networking controller and the OpenSwitch network operating system. Service providers use Inocybe’s platform as a tool for traffic engineering, network automation and network functions virtualization.

Tools like Inocybe’s deliver open source software in a form that’s ready for testing and then deploying in a production environment. The more difficult alternative is downloading the code from a Linux Foundation site and then stitching it together into something useful.

“Open source is free, but making it work isn’t,” Doyle said.

Before the acquisition, Inocybe had a seat on the board of the open source networking initiative within the Linux Foundation and was active in the development of several technologies, including OpenDaylight and OpenSwitch. All that work would continue under Kontron, Zannos said.

Aruba taps ClearPass, Central for SD-Branch management

Aruba, a Hewlett Packard Enterprise company, has unveiled software-based wired and wireless networking for the branch that includes a cloud-managed software-defined WAN.

This week, Aruba introduced the software-defined branch technology at the HPE Discover conference in Las Vegas. The latest product, which comprises software and hardware, operates in conjunction with the Aruba Central cloud-based management platform and the Aruba ClearPass policy manager for network access control.

Combined with Aruba access points and switches, the system provides everything a customer needs to run a LAN and an SD-WAN. The latter is for routing traffic to and from the corporate data center, IoT devices and SaaS and IaaS applications. IoT devices could include surveillance cameras, point-of-sale systems, and air conditioning and heating systems.

Aruba’s offering is best-suited for smaller enterprises with a wireless-first strategy in the branch, said Will Townsend, an analyst at Moor Insights & Strategy, based in Austin, Texas. “When you look at SD-Branch and look at what Aruba is doing, it’s going to be ideally suited for a greenfield deployment — with mobile the trick — and a small to midmarket-type profile of the customer.”

Aruba SD-Branch components

SD-Branch is a recent concept. The approach simplifies networking by using one device for multiple services, such as routing and firewalls. Aruba’s multi-function device is a gateway appliance a customer would deploy on each site.

The device includes an SD-WAN that routes traffic across the branch’s various links, including MPLS, LTE and broadband. The hardware also executes ClearPass access policies for individuals, groups of people, desktops and mobile and IoT devices. IT staff create the policies that define the available infrastructure, applications and data.

“We’re collapsing that SD-WAN functionality into the gateway and now the gateway becomes the central point of policy enforcement within the branch,” said Lissa Hollinger, a vice president of product and solutions marketing at Aruba.

Aruba Central oversees the SD-WAN, as well as the branch’s access points (APs), switches and routers. The cloud-based application also stores reusable configuration templates for gateways, APs and switches. Central uses the ClearPass-generated templates to automatically provision new devices.

Other components of the Aruba system include a headend gateway at the corporate data center that creates an IPsec tunnel to each branch. The device also has a firewall with essential features for bidirectional filtering of data center traffic.

For customers that want more security, Aruba provides the option of integrating the branch gateway with cloud-based firewalls from Check Point Software Technologies, Palo Alto Networks and Zscaler.

“The integration of [data protection] for WAN services and ClearPass for policy management makes this a competitive offering in the marketplace,” said Mark Hung, an analyst at Gartner.

To lessen the workload of IT staff, Aruba offers a mobile installer app. When a gateway, switch or AP arrives at a branch office, a nontechnical person can scan its barcode with the app to ensure the device is for that location. The process avoids getting hardware that isn’t registered to download the preset configurations for that branch.

Primary users of LANs built with Aruba technology include businesses within the retail, hospitality and healthcare industries. Aruba’s largest enterprise customers typically have an IT staff of less than a dozen people managing from 2,500 to 3,000 branch offices, according to Hollinger. 

Aruba sells the SD-Branch technology as part of Aruba Central. The gateways have a starting price of $1,495, plus an annual subscription of $450. Aruba plans to release the technology in July.

Cisco Live 2018: Vendor opens management console to partners

At Cisco Live 2018, the networking vendor continued its emphasis on software, opening Cisco DNA Center to developers and talking up opportunities for channel partners in building solutions on its intent-based networking platform. The Cisco conference was held this week in Orlando.

Cisco said it is releasing developer tools and open APIs into Cisco DNA Center, the control console for the vendor’s intent-based networks. Cisco launched its intent-based networking initiative a year ago, shaking up its network design approach and underscoring its push toward network programmability. In opening DNA Center, Cisco encourages its partners to create applications that take advantage of data collected via Cisco DNA Center.

World Wide Technology Inc. (WWT), a technology solutions provider and Cisco Gold partner based in St. Louis, created a Mobile Ops Center to demonstrate the potential to build upon Cisco’s control center.

“We have only scratched the surface of what is possible with the extensive API set Cisco has built into DNA Center,” said Neil Anderson, practice manager of mobility and access at WWT.

Anderson said WWT plans to use the API capabilities to deliver IT automation on top of Cisco DNA Center and “speed the delivery of our deployments for customers.” In addition, he cited the possibility of integrating across multiple platforms: integrating Cisco DNA with security and IT service ticketing help desk platforms, as well as linking policy in the network with policy in the data center.

Cisco’s move to make DNA Center an open platform is the latest move in the vendor’s ongoing software transformation.

Cisco Live 2018: Developer base grows

The networking vendor used the occasion of Cisco Live 2018 to point to its growing developer base. Susie Wee, vice president and CTO of DevNet innovations at Cisco, said the company’s DevNet developer program has reached the 500,000 registered members mark. “It means we’ve hit critical mass with a developer community who can program the network,” Wee wrote in a Cisco blog post.

According to Cisco, its developer allies include infrastructure developers, cloud developers, independent software vendors (ISVs), systems integrators and network automation consultants. Cisco’s traditional partners — networking resellers — have been retooling in response to Cisco putting software in the lead.

Jason Parry, vice president of client solutions at Force 3, an infrastructure and security solutions provider based in Crofton, Md., said network engineering is becoming more of a development and network programming endeavor. Force 3 is a Cisco Gold partner.

“I think the trend or the move towards software continues to be very evident,” Parry said.

Cisco DNA Center opens opportunities

Parry said Cisco DNA Center will likely follow the path to greater openness that Cisco technologies such as Application Centric Infrastructure have taken.

“We will see them continue to open that up as they have other platforms,” he noted.

The ability to access analytics and telemetry through the Cisco DNA Center APIs will let developers “leverage the network … access layer in ways they really haven’t before,” Parry said. That ability will enable use cases around security, he added.

Fifteen partners have already created solutions on Cisco DNA Center and have demonstrated them at Cisco Live 2018, according to the company. Several of those partners come from the IT services space, including Accenture, Dimension Data, HCL, Logicalis, Presidio, Wipro and WWT.

Cisco said Accenture is creating services around software-image updates, while Presidio focuses on power management and HCL concentrates on third-party device provisioning.

WWT’s Mobile Ops Center, meanwhile, aims to help IT engineers keep tabs on intent-based networks when they are away from the Cisco DNA Center management console.

“Today, DNA Center is a console-based experience — the IT engineer needs to be present at the DNA Center console at his desk to proactively manage and operate the network,” Anderson explained.

He said WWT Asynchrony Labs created a mobile app, using the Cisco DNA Center platform APIs, that lets engineers “take the DNA Center with them wherever they go.”

Dell reverses storage slide

On the heels of its first-quarter earnings report, Dell Technologies highlighted how channel partners are contributing to the company’s growth.

Dell reported $21.4 billion revenue for the first quarter with sales increases in its core technologies. Storage generated $4.1 billion in revenue, which represented a turnaround from a fourth-quarter slump.

“For the first time really since we brought [Dell and EMC] together … we saw phenomenal share gains” in storage, said Cheryl Cook, senior vice president of global channel marketing, at Dell EMC. “It is our first quarter of turning that business back to growth, which has certainly been a focus area for us.”

Among Dell EMC’s recent efforts to boost storage sales were a number of channel incentives and expanded resources such as sales performance incentive funds and the addition of storage sales specialists.

According to Cook, highlights of Dell EMC partners’ first-quarter performance included:

  • Fourteen percent revenue growth in Dell EMC’s distribution business. Distributors continue “to be one of our fastest growth areas of partner types,” she said.
  • Channel partners brought in about 14,800 new or reactivated customers.
  • Dell EMC approved about 120,800 deal registrations.
  • Partners earned more than 5,500 credentials.

Going forward, Cook said that Dell Technologies is looking to create a more integrated framework for partners for doing business across its strategically aligned businesses. That was a key theme discussed at the vendor’s Global Partner Summit in May.

She said Dell Technologies plans to maintain separate partner programs — for example, the VMware and Dell EMC Partner Programs — but will focus on developing ways to recognize partners’ training investments and benefits across programs.

“At some stage, we may drive … ‘loosely coupled alignment’ across the programs rather than [the programs] all living inside one hard program. But we’re very much focused on bringing the value proposition, the benefits and such that we can align our incentive structures similarly [and] recognizing training and credits in each of the programs so that it’s not redundant or repetitive,” she said.

Software-based networks lay foundation of networking’s future

Enterprise networking takes many, constantly changing forms. Today, networking is in the midst of an evolution from hardware to software — a transition to what many call software-based networks that will reshape how companies do business in the years to come.

Software-based networking uses programmability and automation, rather than closed systems housed on proprietary hardware, as the key levers to operate the network. It relies on a variety of concepts — among them software-defined networking, network functions virtualization (NFV) and open source software. Applied properly, software-based networks can increase productivity, reduce downtime and enable an organization to respond more quickly to business and competitive pressures.

But even as the concept gains traction, software-based networking remains in flux. Software-based networks mean different things to different people, and it will take some time for enterprises to sort out which approaches will work best for them.

The reality is that most organizations will use a combination of software-based networking tools in some way. Server virtualization and open source software are already familiar concepts, while enterprises deploy SDN and NFV where they make sense. At the same time, network engineers are beginning to pay attention to the emergence of intent-based networking and its promise that network components can be provisioned and configured automatically.

Software-defined WAN, through its use of virtual connections to enable traffic to flow along multiple paths, has already demonstrated that software-enabled networks can handle the demands of the modern enterprise.

At some point, the lines between software-based networking and legacy networking will disappear, and everything will just be called … networking. But until that day comes, software-based networks open up the possibilities for networking engineers to use a new set of networking tools that better support their businesses.

And it will help them get ready for the next round of changes.

What makes networking automation so difficult?

Ivan Pepelnjak asks the question most network engineers are already deliberating: Why is networking automation so hard?

In a post on IPSpace, Pepelnjak said the challenges facing automation — such as a lack of good tools and APIs — obscure the biggest reason networking automation is so tough to do. And that’s because, as Pepelnjak termed it, “every network is a unique snowflake.”

“You can buy dozens of network management products, download numerous open source tools, and yet you won’t be a single step closer to offering service-level abstraction of your network to your users,” he said.

A better approach might be to build a customizable tool to meet your needs, or to construct a network management system based on Ansible that’s integrated with an orchestration platform.

Or you could just give up, although Pepelnjak advises his readers to consider that decision very carefully before proceeding.

Read what else Pepelnjak has to say about the barriers to automation.

Could Fortnite justify 5G’s development?

Mobile carriers have been spending plenty of money constructing the frameworks necessary for 5G, the next generation of cellular technology. But telcos are still making these investments without knowing if there is a large enough business case to justify the sums they’re spending.

While many investors anticipate the enterprise networking market will be the first real use case for 5G, GlobalData analyst Josh Hewer has a better idea: gaming.

Gamers require connections with low latency and high availability, attributes that 5G connectivity offers, he said. Today, most players are harnessed to Wi-Fi networks, but that could change if higher-speed cellular is an option.

Epic Games, the developer of the smash hit Fortnite Battle Royale, is already pulling in $1 million a day from mobile users — illustrating how lucrative the market could be for 5G carriers.

“Operators are going to have to look outside of the enterprise market to justify early 5G investments,” Hewer said.

With one in three people on the planet paying for games on PC and mobile, according to Hewer, perhaps 5G investors should start to take gaming more seriously.

See the rest of Hewer’s thoughts on 5G and what carriers should consider.

Blockchain and its reliance on decentralization

According to Gartner analyst Rajesh Kandaswamy, it’s simply too early to tell how Blockchain will evolve and what its impact on networking will be.

Kandaswamy tackled two related questions: Is blockchain about decentralization? And can blockchain survive without decentralization?

Alas, a definitive answer is still not possible, Kandaswamy wrote, adding that it’s possible the ledger system can survive either way.

Regardless, he remained encouraged about the role blockchain may play in future networking environments. “Who are we to assume that the paths of future innovation will be restricted to certain ways, when the technology itself is evolving and humankind’s potential for ingenuity is vast?”

Open source networking projects unite under Linux Foundation

The Linux Foundation this week announced the formation of the LF Networking Fund, or LFN, an initiative to combine the multiple open source networking projects currently under its supervision.

Host to many of the top open source networking projects, The Linux Foundation said it was time to streamline how it oversees its various ventures, said Arpit Joshipura, general manager of networking and orchestration at The Linux Foundation.

The six founding open source projects involved in the LFN are FD.io, OpenDaylight, Open Network Automation Platform (ONAP), Open Platform for NFV (OPNFV), PDNA and Streaming Network Analytics System. An additional 83 member organizations are participating in LFN. Members of The Linux Foundation can choose whether they want to join LFN, and they can participate in as many or as few of the projects as they want.

The open source networking projects will remain technically independent, maintaining their existing charters and working toward their individual releases — all of which are still on schedule, according to Joshipura. But the projects will be under a single governing board and will share financial resources and staff, he said.

The governing board will comprise chosen representatives from platinum, gold and silver members of The Linux Foundation. LNF also includes a technical advisory council (TAC) and marketing advisory council (MAC), with individual member representatives. The board and councils will allow LFN members to share project development, testing, deployment and architecture integration best practices, in addition to the regulations across projects.

“The finance, budgets, prioritization and strategy are functions of the governing board, with input from the TAC and the MAC,” Joshipura said. So, if a project requests additional money for testing or is ready for a project release, for example, it goes to the advisory councils with the requests, he added.

Another issue LFN hopes to address is that of onboarding virtual network functions (VNFs). Instead of having inconsistent processes for VNF onboarding, LFN will work toward a single architecture and process to support that effort, Joshipura said.

“We don’t want ONAP to do it one way and OPNFV to do it another way,” he said. “Now, it’s one way to do it across projects.”

The LF Networking Fund still business as usual

While the idea of cross-project collaboration has merit, Joshipura said LFN faces some challenges. One such challenge is simplifying the process to allow developers to join the projects.

“It [includes] a lot more education,” he said. “People do want to participate in other projects, but they’re not familiar with them. So, we want to make sure we bring the training from one project to another project.”

Lee Doyle, principal analyst at Doyle Research, said another issue that could trip up the initiative is the fact that The Linux Foundation is still a business — and all of these open source networking projects will still compete with each other.

“The Linux Foundation isn’t altruistic,” Doyle said. “It’s a business. People are still going to fight for resources and sponsors.”

While Joshipura stressed that the formal legal system outlined within LFN will make discussions and decisions simpler, Doyle said it still means a bunch of meetings.

It’s a laudable goal, he said, but any progress within the LF Networking Fund will take time.

Apstra bolsters IBN with customizable analytics

Startup Apstra has added to its intent-based networking software customizable analytics capable of spotting potential problems and reporting them to network managers.

Apstra introduced this week intent-based analytics as part of an upgrade to the company’s Apstra Operating System (AOS). The latest version, AOS 2.1, also includes other enhancements, such as support for additional network hardware and the ability to use a workload’s MAC or IP address to find it in an IP fabric.

In general, AOS is a network operating system designed to let managers automatically configure and troubleshoot switches. Apstra focuses on hardware transporting Layer 2 and Layer 3 traffic between devices from multiple vendors, including Arista Networks, Cisco, Dell and Juniper Networks. Apstra also supports white-box hardware running the Cumulus Networks OS.

AOS, which can run on a virtualized x86 server, communicates with the hardware through installed drivers or the hardware’s REST API. Data on the state of each device is continuously fed to the AOS data store. Alerts are sent to network operators when the state data conflicts with how a device is configured to operate.

AOS 2.1 takes the software’s capabilities up a notch through tools that operators can use to choose specific data they want the Apstra analytics engine to process.

“This is a logical progression for Apstra with AOS,” said Brad Casemore, an analyst at IDC. “Pervasive, real-time analytics should be an integral element of any intent-based networking system.”

Using Apstra analytics

The first step is for operators to define the type of data AOS will collect. For example, managers could ask for the CPU utilization on all spine switches. Also, they could request queries of all the counters for server-facing interfaces and of the routing tables for links connecting leaf and spine switches.

Mansour Karam, CEO, ApstraMansour Karam

“If you were to add a new link, add a new server, or add a new spine, the data would be included automatically and dynamically,” Apstra CEO Mansour Karam said.

Once the data is defined, operators can choose the conditions under which the software will examine the information. Apstra provides preset scenarios or operators can create their own. “You can build this [data] pipeline in the way that you want, and then put in rules [to extract intelligence],” Karam said.

Useful information that operators can extract from the system include:

  • traffic imbalances on connections between leaf and spine switches;
  • links reaching traffic capacity;
  • the distribution of north-south and east-west traffic; and
  • the available bandwidth between servers or switches.

Enterprises moving slowly with IBN deployments

Other vendors, such as Cisco, Forward Networks and Veriflow, are building out intent-based networking (IBN) systems to drive more extensive automation. Analytics plays a significant role in making automation possible.

“Nearly every enterprise that adopts advanced network analytics solutions

is using it to enable network automation,” said Shamus McGillicuddy, an analyst at Enterprise Management Associates, based in Boulder, Colo. “You can’t really have extensive network automation without analytics. Otherwise, you have no way to verify that what you are automating conforms with your intent.”

Today, most IT staffs use command-line interfaces (CLIs) to manually program switches and scores of other devices that comprise a network’s infrastructure. IBN abstracts configuration requirements from the CLI and lets operators use declarative statements within a graphical user interface to tell the network what they want. The system then makes the necessary changes.

The use of IBN is just beginning in the enterprise. Gartner predicts the number of commercial deployments will be in the hundreds through mid-2018, increasing to more than 1,000 by the end of next year.
