Arista to pay $400M to Cisco, resolving patent dispute

Cisco and Arista reached a settlement resolving their long-running patent dispute.

Under the deal, Arista will pay $400 million to Cisco, and Cisco agrees not to assert against Arista patents that were included in the litigation as long as Arista shall continue to implement workarounds it had put in place to certain of those patents.

In an SEC 8-K filing, Cisco also said Arista agreed to make certain changes to the user interfaces of its products.

The parties also to use an arbitration process to resolve any further patent infringement claims for the next three years, and not to bring to an action against the other for patent or copyright (except for any claims of source code misappropriation) infringement for the next five years.


Cisco Hits Arista with Multiple Patent Lawsuit

Cisco filed a patent infringement lawsuit against Arista Networks, claiming that a dozen key switching features covered by 14 different U.S. patents held by Cisco were copied.

In a blog post, Mark Chandler, General Counsel at Cisco, writes that none of these features are incorporated in industry standards andy were patented by individuals who worked for Cisco and are now at Arista, or who at Cisco worked with executives who are now at Arista. Specifically, Cisco's complaint cites the following technologies that are incorporated by Arista in their entirety into Arista’s products.

  • System Database (“SysDB”) (Arista uses Cisco’s networking device implementation covered by Cisco Patent No. 7,162,537)
  • Zero-Touch Provisioning (“ZTP”) (Arista uses Cisco’s implementation covered by Cisco Patent No. 7,290,164)
  • On Board Failure Logging (“OBFL”) (Arista uses Cisco’s implementation covered by Cisco Patent No.7,340,597)
  • Control Plane Policing (“CoPP”) (Arista uses Cisco’s implementation covered by Cisco Patent No. 7,224,668)
  • Spanning Tree Loop Guard(Arista uses Cisco’s implementations covered by Cisco Patent Nos. 7,460,492 & 7,061,875 )
  • In-Service System Upgrades (“ISSU”) (Arista uses Cisco’s implementation described by Cisco Patent No. 8,356,296)
  • Virtual Port Channels (“vPC”) (Arista uses Cisco’s implementation covered by Cisco Patent No 8,051,211)
  • Access Control ListsImprovements (“ACL”) (Arista uses Cisco’s implementation covered by Cisco Patent Nos. 7,023,853 & 6,377,577)
  • Private Virtual Local Area Networks (“Private VLANs”) (Arista uses Cisco’s implementation covered by Cisco Patent Nos. 6,741,592 & 7,200,145)
  • Generic Command Interface (Arista uses Cisco’s implementation covered by Cisco Patent No. 7,047,526)
  • CLI Command Data Translation (Arista uses Cisco’s implementation covered by Cisco Patent No. 7,953,886)
Furthermore, Chandler argues that "Arista promotes the theft of Cisco’s intellectual property as a key differentiator for Arista versus other Cisco competitors."

Arista introduces leaf and spine switches powered by Barefoot silicon

Arista Networks introduced a family of multi-function leaf and spine platforms powered by Barefoot Networks' Tofino series of P4-programmable Ethernet switch chips.

The new Arista 7170 Series switches, which run the Arista EOS (Extensible Operating System) SDK, can boost server performance by offloading Hypervisor vSwitch networking functions such as tunnel termination, security policy enforcement and address translation onto the leaf switch, allowing more work to be accomplished by the compute pool, saving equipment costs and lowering power and cooling.

The 7170 Series is available in two configurations to address both leaf and spine roles:
  • The 2U 7170-64C supports up to 64 ports of 100G or 12.8Tbps, with up to 5Bpps of packet forwarding and a fully shared packet buffer.
  • The 7170-32C is a compact 1U with 32 ports of 100G and the same range of profiles.

The 7170 Series is available now, with a choice of EOS Profiles. Additional profiles will be released over time, with the security and telemetry profiles planned for August 2018. Pricing starts at $1200/100G port for the 64 x 100G system.

“With the Arista 7170 Series and EOS we are able to offer new and interesting features that leverage the flexible pipeline of the 7170 Series. At the same time, we took advantage of the programmability to increase the scale of many existing features for tunnel encapsulation, filtering, traffic analysis and address translation,” said Hugh Holbrook, Vice President, Software Engineering for Arista Networks.

"With Tofino, Barefoot has proven that programmability can be delivered without compromise on performance and I believe that future switch chips will be fully programmable - there is no reason not to. It allows protocols to be lifted up and out of hardware into software. Arista’s first Tofino based platforms do exactly that, using P4 to deliver customized profiles to their customers. Programmable switches take differentiation in the market to a whole new level. This is going to get interesting.” said Nick McKeown, Chief Scientist and Co-Founder at Barefoot Networks.

Alibaba, AT&T, Baidu, Tencent adopt Barefoot forwarding plane


Barefoot Networks, a provider of advanced, high speed switching technology, announced significant market momentum driven by growing demand for its programmable forwarding plane technology.

Barefoot's 6.5 Tbit/s Tofino switch, which is claimed to be the fastest and P4-programmable switch chip, has been sampling to customers since the fourth quarter of 2016. The company noted that its technology is being adopted by large enterprises and telecommunications providers to increase network performance and efficiency through leveraging programmable forwarding plane technology.

Barefoot stated that it has recently worked with AT&T and SnapRoute to deliver what it believes is the first real-time path and latency visualisation. Utilising Tofino and In-band Network Telemetry (INT), AT&T was able to gain deep insight into the network down to packet-level for the first time to help to address bottlenecks caused by path or latency variation.

Barefoot noted it took 6 weeks to develop the visualisation capability before it was deployed into AT&T's production environment carrying live customer traffic over a Washington DC to San Francisco link.

In addition, major Internet companies Alibaba, Baidu and Tencent have used Tofino and P4 to address challenges in their networks. Barefoot noted that the demands of mega-scale data centres are growing to support new applications and services, while legacy fixed-function switching technology is not sufficiently flexible and so they are using Barefoot to develop custom forwarding planes. The companies are therefore able to adopt load balancing, DDoS protection and INT features without affecting performance.

Barefoot has also expanded its ecosystem via partnerships with equipment manufacturers based in Asia. To date, the company has announced go-to-market partnerships with Edgecore Networks, WNC, H3C, Ruijie and ZTE. These partnerships are designed to enable Barefoot to meet growing demand for programmable networking across a range of network environments.



  • Barefoot Networks, based in Palo Alto, California, exited stealth and unveiled its user-programmable Tofino switch chip in June 2016. Founded in 2013, Barefoot is backed by investors including Andreessen Horowitz, Lightspeed Venture Partners and Sequoia Capital. The company has raised approximately $155 million in five funding rounds, most recently raising $23 million in November 2016 in a round led by Alibaba and Tencent.

Broadcom brings new Ethernet programmability with open source logical table software

Broadcom is introducing a new approach to Ethernet switch configuration that makes use of open source software to allow network hard vendors, OS vendors and even enterprise network managers to monitor, analyze, and provision switch resources through a standard software interface.

This capability is enabled by a new Software Development Kit Logical Table (SDKLT) for Broadcom switch ASICs that leverages table-based programming, where all the device physical resources such as MAC Address Tables, L3 route tables, TCAMs, etc. are exposed as logical tables. Device-specific information is stored in databases and not embedded in the APIs. Device-specific behavior is managed by logical tables through a small set of APIs. Broadcom said this approach introduces new ways to monitor, analyze and provision switch resources, all through industry standard automation tools. The company is making this logical table programmability available as an open source SDK.

Broadcom's first open source offering of the SDKLT is for BCM56960 Tomahawk switch, which is widely used in data center top-of-rack (TOR) switches. The SDKLT open source code is posted on GitHub. The open source code and the Logical Table APIs are released under Apache 2.0 license. The software is designed for High Availability (HA) including support for Soft Error Recovery, Warmboot, and In Service Upgrades.

“The SDKLT brings a fresh, state-of- the-art software development approach to the broader community of network software developers where they can now fully and directly control and monitor the rich switch feature set optimized for SDN and cloud use cases,” said Ram Velaga, senior vice president and general manager of switching products.

Barefoot's Deep Insight monitoring leverages P4 programmable switching silicon

Barefoot Networks, a start-up developing user-programmable switching chips, introduced a network monitoring system designed to provide visibility into every packet in a network.

The Barefoot Deep Insight software, which can run on commodity servers and in a network powered by switches based on Barefoot’s "Tofino" programmable switch chip, can interpret, analyze and pinpoint packet telemetry. Using stateful baselining of a network's performance, the company says its software automatically filters out irrelevant data, detecting only anomalies at any time scale and with nanosecond resolution. The Deep Insight software is able to track the sequence of switches the packet visited along its path, the set of rules it matched upon at every switch along the way, the time it spent buffered in every switch, to the nanosecond, and the packets, flows and application that the packet shared each queue with.

“Network monitoring is still stuck in the dark ages,” said Nick McKeown, co-founder and chief scientist at Barefoot Networks. “To get detailed visibility, some network owners are forced to deploy a second network that costs more than the first, just to watch what their network is doing. With Deep Insight, every switch in the network gathers data for you without any additional hardware, and without generating additional traffic. Deep Insight sits at the network edge, detecting and reporting network anomalies.” 

Barefoot is offering the network monitoring system on a pay-as-you-grow model, where customers pay only for the volume of telemetry they need.

Barefoot said its Deep Insight system could be especially useful in enterprise data centers, where many-to-one traffic patterns associated with applications such as Hadoop and HDFS can result in congestion, queue build-up and increases end-to-end latency. The Tofino switching silicon can detect the queue build-up and take a snapshot of every packet header during the congestion event. The Deep Insight software could then be used "to visualize the full dynamic of a congestion event, down to each individual packet, exposing the aggressors and the victims flows."

Barefoot is also highlighting the P4 programmability of its Tofino chip. This provides the flexibility to design for specific use cases without writing data plane code or modifying the silicon.

  • Cisco Systems continues to drive the growth in 25GbE data center switching, with its Cloud Scale Nexus 9000 platform comprising the vast majority of total 25GbE market shipments.
  • Despite the strong 25GbE increase, 10GbE shipments continued to show robust growth, with overall data center switch shipments increasing in excess of 10% year-over-year on the strength
  • of very healthy 10GBASE-T adoption in both enterprise and service provider data center networks.

The strong initial adoption of 25GbE and 100GbE data center switches is in keeping with Crehan’s January 2017 long-range forecast, which noted that 25GbE and 100GbE were expected to ramp rapidly and comprise over half of all shipments by 2021.

BT evaluates Dell EMC's disaggregated switches

BT is evaluating the performance of Dell EMC disaggregated switches against traditional integrated switching hardware to test the performance, economics and programmability of this new, virtualized approach, which is important as customers increasingly require more flexible, agile networks.  The proof-of-concept is running at BT Labs in Adastral Park, Suffolk.

Dell EMC said disaggregated switches have several potential advantages over traditional network switches, as they can be managed flexibly using Netconf protocol and YANG models. This makes the entire system inherently programmable and allows the switches to be operated in concert to spin up new network services or make configuration changes rapidly.

BT and Dell EMC are evaluating a number of potential use cases as part of the trial, including instant activation of Ethernet circuits from a third party (such as an enterprise), and the ability of the system to deliver real-time network operational data. The platform also has the potential to deliver other programmable use cases such as bandwidth calendaring – flexing the bandwidth of an Ethernet circuit according to customer need via a predetermined calendar – and delivering network telemetry data to third parties automatically.

Neil J. McRae, chief architect for BT said, “This proof-of-concept trial with Dell EMC will enable us to evaluate the performance of disaggregated switches against traditional integrated network switches, and make informed decisions about the role this kind of solution will play in the dynamic network services of the future. We’re determined to ensure that BT’s network continues to be world-class and able to deliver the services our customers need, when and how they need them. Agility and programmability, maximizing the benefits of SDN, are therefore key to our future network evolution.”

Alibaba, AT&T, Baidu, Tencent adopt Barefoot forwarding plane

Barefoot Networks, a provider of advanced, high speed switching technology, announced significant market momentum driven by growing demand for its programmable forwarding plane technology.

Barefoot's 6.5 Tbit/s Tofino switch, which is claimed to be the fastest and P4-programmable switch chip, has been sampling to customers since the fourth quarter of 2016. The company noted that its technology is being adopted by large enterprises and telecommunications providers to increase network performance and efficiency through leveraging programmable forwarding plane technology.

Barefoot stated that it has recently worked with AT&T and SnapRoute to deliver what it believes is the first real-time path and latency visualisation. Utilising Tofino and In-band Network Telemetry (INT), AT&T was able to gain deep insight into the network down to packet-level for the first time to help to address bottlenecks caused by path or latency variation.

Barefoot noted it took 6 weeks to develop the visualisation capability before it was deployed into AT&T's production environment carrying live customer traffic over a Washington DC to San Francisco link.

In addition, major Internet companies Alibaba, Baidu and Tencent have used Tofino and P4 to address challenges in their networks. Barefoot noted that the demands of mega-scale data centres are growing to support new applications and services, while legacy fixed-function switching technology is not sufficiently flexible and so they are using Barefoot to develop custom forwarding planes. The companies are therefore able to adopt load balancing, DDoS protection and INT features without affecting performance.

Barefoot has also expanded its ecosystem via partnerships with equipment manufacturers based in Asia. To date, the company has announced go-to-market partnerships with Edgecore Networks, WNC, H3C, Ruijie and ZTE. These partnerships are designed to enable Barefoot to meet growing demand for programmable networking across a range of network environments.



  • Barefoot Networks, based in Palo Alto, California, exited stealth and unveiled its user-programmable Tofino switch chip in June last year. Founded in 2013, Barefoot is backed by investors including Andreessen Horowitz, Lightspeed Venture Partners and Sequoia Capital. The company has raised approximately $155 million in five funding rounds, most recently raising $23 million in November 2016 in a round led by Alibaba and Tencent.
