Juniper revs new Ethernet switches for the multicloud world

Juniper Networks introduced a new line of Ethernet switches designed for the new era of multicloud networking, where the assumption that distributed enterprises will access resources from multiple data centers is a reality.

The rollout includes new switches for the enterprise data center, campus, and branch, as well as a new cloud-based management platform called Sky Enterprise. Junos remains central to all of the new products and the rest of the existing switching portfolio.

“The promise of multicloud is to deliver an infrastructure that is secure, ubiquitous, reliable and fungible and where the migration of workloads will be a simple and intuitive process,” said Bikash Koley, chief technology officer at Juniper Networks. “For IT to be successful in becoming multicloud-ready, it is critical organizations consider not only the data center and public cloud, but also the on-ramps of their campus and branch networks. Otherwise, enterprises will face fractured security and operations as network boundaries prevent seamless, end-to-end visibility and control.”

Highlights of the announcement include:

  • A new QFX10002-60C "universal" switch for data center spine, data center edge and data center interconnect (DCI).  It features 60x100 Gigabit Ethernet (GbE) deep-buffer interfaces. 
  • A new QFX5210-64C 64x100GbE port spine switch
  • A new QFX5200-48Y 48x25GbE top-of-rack switch
  • A new QFX MACsec line card addition for the QFX10000 modular switches. This card provides 30-port 100GbE connectivity for encrypted traffic in and between data centers.
  • Juniper Sky Enterprise - a cloud management service that enables operators to deploy, configure and manage switching and security devices, reducing change errors by up to 90 percent. Sky Enterprise also gives network operators visibility into wireless access points using Aerohive Hive Manager NG API integration.
  • New EX2300 and EX4300 compact switches for campus networks. The EX4300 multigig switch supports POE++ for new applications and MACsec to enable a secure on-ramp to the cloud. The EX9250 switch is a compact campus core that gives enterprises multiple fabric options by supporting both Junos Fusion and EVPN-VXLAN.
  • New NFX150 Network Services Platform for branch offices. This combines native branch security and hybrid WAN functionality with wireless 4G and LTE connectivity between branches. Built as an extensible platform, it can run third-party virtual network functions (VNFs).
  • Contrail SD-WAN with new subscription-based pricing: Juniper’s Contrail SD-WAN solution bundles the SRX Series Services Gateway and the NFX Series with the platform and orchestration software required for multicloud-ready SD-WAN. New subscription pricing bundles provide several physical and virtual endpoint options with secure SD-WAN management.

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.

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: Branded Data Center Ethernet Switch Revenue Tops $10B in '16

Branded data center Ethernet switch sales exceeded $10 billion in 2016, according to the latest report from Crehan Research Inc.  The report notes that this revenue level, a record, was accompanied by the strongest market growth rate since 2013.

“2016 was a strong year for data center Ethernet switching, with robust customer spending on public, private and hybrid clouds," said Seamus Crehan, president of Crehan Research. “40GbE and 100GbE switches were the main market drivers, with a total of over one billion dollars in revenue growth. However, 40GbE data center switch spending softened in the second half of the year, while spending on 100GbE continued to increase throughout the year."

In addition to the strong top-level revenue performance, notable results from Crehan’s data center switch report include:

  • 25GbE shipments ramped exponentially during 2016, exceeding a one-and-a-half million annual port run-rate by 4Q16, driven mostly by Cisco’s Cloud Scale Nexus 9000 series 
  •  100GbE shipments increased dramatically throughout the year, also surpassing a one-and-a-half million annual port run-rate by 4Q16, with data center switches from Arista and Cisco accounting for most of the year’s volume 
  • 10GBASE-T data center switch shipments increased more than 60% for the full year 2016  Cisco accounted for over half of total branded data center Ethernet switch revenues in 2016 
  • Arista, Huawei and Juniper all saw data center switch revenue increases in excess of 30% in 2016, resulting in share gains  
  • The top-line 2016 average selling price per data center switch port was almost identical to that of 2015  

“The total market average selling price remained remarkably stable in 2016, despite factors such as intense data center switch competition and the price negotiating power of the large hyper-scale cloud customers," Crehan said. "Migration to higher speeds and strong adoption of modular switching were key factors in the stability.”

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.

Arista's AlgoMatch Targets Advanced Network Enforcement

Arista Networks introduced an advanced network enforcement mechanism for providing customers with more flexible and scalable access control, telemetry and secure cloud networking.

Arista AlgoMatch combines general purpose memory technology with advanced software algorithms. The company said its AlgoMatch innovation provides more scale, performance and efficiency compared to TCAMs (Ternary Content Addressable Memories) commonly used in traditional silicon chipset architecture. AlgoMatch provides a packet matching algorithm that enables flow matching for access control, policy and visibility. Benefits include a high performance network policy engine with increased functionality and scale delivered in a cost and power efficient manner.

The company also introduced its new Arista 7160 Series 25/100GbE programmable platforms, including three models, all featuring 25/100GbE ports. The new platform delivers operational consistency and automated efficiency through the same common Arista EOS (Extensible Operating System) and CloudVision software.

The 7160 Series is available in three models:

  • 7160-32CQ - 32 x 100GbE, 1RU, or 128 x 25GbE with 6.4Tbps of performance
  • 7160-48YC6 - 48 x 25GbE, 6 x 100GbE with 3.6Tbps of performance
  • 7160-48TC6 - 48 x 10GbE BASE-T, 6 x 100GbE and 2.16Tbps of performance

“25GbE offers a 2.5X performance improvement over 10GbE at a significant price-per-gigabit discount while using the same cabling infrastructure,” said Seamus Crehan, president of Crehan Research. “Unrelenting traffic growth, large scale cloud adoption and the recent release of the IEEE standard are already starting to drive the demand for server networking upgrades to speeds of 25, 50 and 100GbE where we expect combined shipments to surpass two million ports by 2017. This, in-turn, is fueling the strong demand for next generation 25GbE and 100GbE switches.”

AlgoMatch will ship on the Arista 7160 Series in Q1 2017.
