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.

Marvell Unveils 802.1BR-compliant Prestera PX PIPE for Data Centres

Marvell, a major provider of storage, networking and connectivity semiconductor solutions, has introduced its new Prestera PX Passive Intelligent Port Extender (PIPE) family, designed to significantly reduce power consumption, complexity and cost in the data centre.

Marvell noted that data centres featuring 10 and 25 Gigabit Ethernet port speeds have faced challenges with regards to lowering opex and capex costs as bandwidth demand increases. The new purpose-built PIPE port extender solution from Marvell supports the IEEE 802.1BR standard and is designed to offer a new approach for the deployment of top of rack (ToR) switches that enables a claimed halving in both the power and cost compared with a traditional Ethernet switch.

PIPE technology allows data centres to be architected using a simplified, low cost and low power port extender in place of the ToR switch and shifts the heavy duty switching functionality upstream. The company noted that as the industry transitions from 10 to 25 Gigabit Ethernet and from 40 to 100 Gigabit Ethernet port speeds, data centres require a new, modular building block to bridge the range of current and next-generation port speeds.

Marvell’s PIPE family is designed to provide a flexible and scalable solution that can simplify and speed the transition to higher port speeds via support for multiple configuration options of Ethernet connectivity for a range of port speeds and densities.

Through the implementation of IEEE 802.1BR and removing the need for per-box management, Marvell aims to streamline network development and simplify centralised management of the hundreds of thousands of ports in a data centre. To facilitate the adoption of PIPE, it incorporates a programmable packet header editor that provides interoperability with a range of networking equipment. Marvell's PIPE solution also integrates fast-fail-over and resiliency functionality for high availability applications.

Marvell noted that it collaborated with leading ODMs and OEMs to deliver Prestera PX-ready platforms for ToR switch applications. Samples and reference designs for the Prestera PX family of solutions are available immediately.

In October 2016, Marvell introduced an optimised 25 Gigabit Ethernet end-to-end data centre solution designed as an alternative to 10 Gigabit Ethernet solutions and to provide more computing bandwidth and improved efficiency to help operators handle increasing data traffic volumes. The 25 Gigabit Ethernet solution integrates its IEEE 25/100 Gigabit Ethernet-compliant Prestera switches and Alaska Ethernet transceivers and targets ToR applications.

Marvel claims that the Prestera devices with integrated 25 Gbit/s PHYs enable data centres to breach the 1 W per-25 Gbit/s port barrier for 25 Gbit/s ToR applications.

Crehan: 25GbE and 100GbE > 50% of Data Center Ethernet Switch Shipments by 2021

Over half of all data center Ethernet switch shipments by 2021 will be 25 gigabit Ethernet (GbE) and 100GbE, according to a new report from Crehan Research that also predicts that these two technologies will be most instrumental in driving this market beyond $15B by that time.

“25GbE and 100GbE data center switch adoption is already experiencing exponential growth, with port shipments currently in the hundred-of-thousands per quarter,” said Seamus Crehan, president of Crehan Research. "Volumes would likely be even higher if it weren’t for pockets of supply constraints in certain areas, such as the optical transceivers that uplink and connect many of these switches.”

Some of the factors driving the current strong ramp and expected future high volumes of 25GbE and 100GbE data center Ethernet switching include:

  • Very small – and in some cases no – price premium over comparable 10GbE and 40GbE switches, resulting in very substantial bandwidth discounts.
  • Higher bandwidth per lane since 25GbE currently uses the same number of lanes as 10GbE and 100GbE currently uses the same number of lanes as 40GbE.
  • Compatibility with existing data center fiber cabling.
  • Very strong interest, and even some pent up demand, from the largest hyper-scale cloud providers, which can drive significant early volumes and reduce costs even further. Already some of these providers have major artificial intelligence and deep machine learning initiatives. 25/100GbE network architectures, in conjunction with compute and network accelerators, will likely be instrumental in enabling the cost-effective scaling of these types of workloads.

Crehan’s latest Data Center Switch Long-Range Forecast Report further predicts that as a result of the strong adoption of 25GbE and 100GbE, SFP-based 10GbE and QSFP-based 40GbE data center switch shipments will decline in 2017. In contrast, 10GBASE-T data center switching is expected to continue growing robustly for some time.

Barefoot Unveils 6.5 Tbps Tofino Switching Chip

Barefoot Networks, a start-up based in Palo Alto, California emerged from stealth to unveil its "Tofino" switching chip and announce that it has raised $130 million, including a strategic investment from Google.

Dubbed "the fast switch every built", Barefoot’s programmable Tofino switch chip processes packets at 6.5 terabits per second, twice as fast as the previous record holder. While conventional programmable network devices such as NPUs have orders of magnitude slower than their fixed-function brethren, Barefoot said its Tofino silicon provides the first programmable forwarding plane while setting a new performance benchmark for performance, power, and price.

The silicon is designed for user programmability via the open-source P4 programming language, enabling precise control over packets and bringing entirely new features into the switch—for example, features that replace load balancers, features that replace firewalls, features that add packet-by-packet telemetry enabling rapid debug of distributed application behavior.

Barefoot said the open-source P4 language provides software developers with the compilers, tools, and applications they need to successfully program the fastest networking gear. This could eliminate "middle boxes" that add latency, complexity and cost to a data center network. Barefoot’s new compiler technology has taken P4 programs – written by customers – and converted them into blazing-fast running code executed on Tofino.  Barefoot will open an ecosystem of compilers, tools and P4 code to make P4 accessible.

Barefoot Networks also disclosed that it has recently closed a $57 million funding round led by Goldman Sachs Principal Strategic Investments and Google Inc. This brings total funding to more than $130 million to date.

“The basic fixed-function switch architecture was set in 1996 and has remained unchanged for twenty years,” noted Nick McKeown, co-founder and chief scientist at Barefoot Networks. “Yet everything else in the data center changed. We went from monolithic software to VM’s and then to containers and fully distributed applications. With the rise of the cloud, data center traffic patterns changed as did the role of the data center. How could a 1996 switching architecture be the right foundation for 2016’s applications? In all other parts of the data center we have moved to programmability. Tofino enables this move for networking. It empowers network owners and their infrastructure partners to design, optimize and innovate to their specific requirements.”

"Mega-scale data center operators greatly benefit from building their own networking equipment and writing the software that runs on it. The forwarding plane, though, has been off-limits to programmers because of the rigid nature of high-performance switching solutions,” noted Martin Izzard, co-founder and CEO, Barefoot Networks.  “With P4 and Barefoot, the landscape is changing; users can develop the P4 programs to define the innovative forwarding plane behavior, introducing new ways to monitor and analyze network traffic, making networks more reliable, scalable, efficient and secure."

Crehan: Spending Spikes for Branded Data Center Ethernet Switches

In the first half of 2016, spending on branded data center Ethernet switches saw the strongest growth since the first half of 2012, according to the most recent report from Crehan Research Inc.

The market’s growth rate in the first half of 2016 approximately doubled the rate seen in the previous two years leading to record results, according to the report.

“Customer spending and deployments of branded data center Ethernet switches accelerated significantly during the first half of this year due to a number of factors," said Seamus Crehan, president of Crehan Research.

“First, we have seen the recent introduction of numerous products with compelling features and value propositions including programmability, automation, and telemetry, which help to enable software-defined data center networks. Second, we are seeing the price per gigabit of bandwidth drop significantly, enticing customers to upgrade their existing infrastructure. And lastly, we are seeing a lot of early excitement and interest around 100 gigabit Ethernet switching, where data center shipments have gone from about ten thousand ports in the first half of 2015 to well over one-hundred thousand ports in the first half of 2016."

Some highlights:


  • Over half of all spending on branded data center Ethernet switches during the first half of 2016 was on Cisco products, with particularly strong adoption of the company’s Nexus 3000 and 9000 lines. 
  • The strongest vendor revenue growth during the same time period was seen by Arista and Huawei, each of which increased revenues by over thirty percent in comparison to the first half of 2015. 
  • Juniper Networks’ revenue also had a very healthy increase – in the twenty-percent range – as its QFX portfolio of data center Ethernet switches saw strong acceptance within the telco, cable and cloud service provider markets.
