IEEE Publishes IEEE 802.3cc-2017 25 Gb/s Ethernet Standard

IEEE announced the publishing and availability of its 802.3cc-2017—Standard for Ethernet Amendment: Physical Layer and Management Parameters for Serial 25 Gb/s Ethernet Operation Over Single-Mode Fiber.

The new amendment to IEEE 802.3 addresses the growing need for increased Ethernet speeds for enterprise, campus and metro Ethernet speeds exceeding 10 Gb/s, and that can support reaches up to 10 and 40 kilometers over single-mode fiber (SMF).

IEEE 802.3cc supports efficient Ethernet operation and defines single-lane 25 Gb/s PHYs for operation over single-mode fiber with lengths up to 10 km and 40 km. IEEE 802.3cc addresses the requirement in metropolitan networks, where the core operates at 100 Gb/s, for tributary feeds at rates higher than 10 Gb/s. By enabling extended 25 Gb/s reaches, IEEE 802.3cc matches the per-lane rate of several 100 Gb/s PMDs currently used in these networks.

“IEEE 802.3cc provides network operators a cost-effective upgrade path to 25 Gb/s that minimizes network design, installation and maintenance costs by preserving current network architecture, management, and software,” said David Lewis, chair, IEEE 802.3cc 25 Gb/s Ethernet over Single-Mode Fiber Task Force. “The work of the IEEE 802.3cc 25 Gb/s Ethernet over Single-Mode Fiber Task Force has demonstrated how responding quickly to industry demand for greater energy-efficient Ethernet capabilities can be achieved in a manner that can reduce both operational costs, and the environmental footprint of network upgrades.”

CenturyLink vaults to top of U.S. Ethernet LEADERBOARD

CenturyLink has captured the #1 spot on Vertical Systems Group's latest LEADERBOARD of U.S. Ethernet market leaders. It is the first time a provider other than AT&T has led the benchmark ranking since 2005.

Seven companies achieved LEADERBOARD status for 2017 (in rank order based on retail port share): CenturyLink, AT&T, Verizon, Spectrum Enterprise, Comcast, Windstream and Cox.

CenturyLink’s advance was driven by its November merger with Level 3, along with continued growth in Ethernet ports for both companies. Previously, Level 3 ranked second to AT&T and CenturyLink ranked fifth on the Mid-2017 U.S. Ethernet LEADERBOARD.

To qualify for the LEADERBOARD, network providers must have four percent (4%) or more of the U.S. Ethernet services market. Shares are measured by the number of billable retail customer ports in service as tracked by Vertical Systems Group.

“In addition to the shakeup at the top of the LEADERBOARD, U.S. Ethernet installations exceeded the milestone of one million ports in 2017,” said Rick Malone, principal of Vertical Systems Group. “Overall, the fastest growing Ethernet deployments were driven by higher speed cloud connectivity and IP VPN access. Service providers cite price compression as a continuing challenge, as well as delayed network purchase decisions due to SD-WAN evaluations.”

Highlights of Vertical’s year-end 2017 U.S. Ethernet market share analysis:

  • The U.S. retail Ethernet port base grew 13% in 2017 and finished the year with more than one million ports.
  • Seven Ethernet providers qualified for the 2017 LEADERBOARD, as compared to nine in 2016. The two company exits were XO (acquired by Verizon) and Level 3 (merged with CenturyLink). As a result, the U.S. LEADERBOARD has no companies from the Competitive Provider segment for the first time.
  • Four Incumbent Carriers (CenturyLink, AT&T, Verizon, Windstream) and three Cable MSOs (Spectrum Enterprise, Comcast, Cox) are represented on the latest LEADERBOARD.
  • Comcast had the highest organic growth rate of the LEADERBOARD companies in 2017, growing its base of Ethernet ports appreciably without an acquisition.
  • Six Ethernet providers qualified for the 2017 Challenge Tier, as compared to four in 2016. New entrants Frontier and GTT moved up into the Challenge Tier from the Market Player tier based in part on acquisitions of Ethernet assets. These companies join Altice USA, Cogent, Sprint and Zayo.
  • Each of the seven LEADERBOARD companies has attained MEF CE 2.0 Ethernet services certification, and each employs MEF Carrier Ethernet Certified Professionals (MEF-CECPs). Spectrum Enterprise leads with more than 800 MEF-CECPs, followed by CenturyLink with greater than 500. Companies on the U.S. Ethernet LEADERBOARD plus Challenge Tier employ more than one-third of the 5,500+ MEF-CECPs worldwide.

In addition to the roster of LEADERBOARD providers, all other companies selling Ethernet services in the U.S. are segmented into two tiers as measured by port share. The first or Challenge Tier includes providers with between 1% and 4% share of the U.S. retail Ethernet market. For year-end 2017, the following six companies attained a position in the Challenge Tier (in alphabetical order): Altice USA, Cogent, Frontier, GTT, Sprint and Zayo.

The second or Market Player tier includes all providers with port share below 1%. Companies in the Market Player tier include the following providers (in alphabetical order): Alaska Communications, Alpheus Communications, American Telesis, Birch Communications, BT Global Services, Cincinnati Bell, Consolidated Communications, Crowne Castle, DQE Communications, Expedient, FiberLight, FirstLight, Global Cloud Xchange, Great Plains Communications, Hawaiian Telecom, Logix Fiber Networks, LS Networks, Lumos Networks, Masergy, MegaPath, Midco, NTT America, Orange Business, RCN Business, Tata, TDS Telecom, Telstra, TPx Communications, Unite Private Networks, US Signal, WOW!Business and other companies selling retail Ethernet services in the U.S. market.

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.

Crehan: 400GbE to drive most data center Ethernet switch bandwidth by 2022

Expect to see initial shipments of 400 gigabit Ethernet (GbE) switches this year and look for exponential growth ahead. The 400 GbE technology will drive the majority of data center Ethernet switch bandwidth by 2022, according to a newly published Data Center Switch Long-Range Forecast Report from Crehan Research Inc.

“Beginning with high-density 100GbE systems, we entered a new era of much faster data center switch upgrades, and that trend is predicted to continue with 400GbE,” said Seamus Crehan, president of Crehan Research.  "With its expected market-leading price per gigabit and no foreseeable shortage of demand for higher-speed networking capacity in cloud data centers, 400GbE should surpass a million ports shipped in less time than it took 100GbE to reach that threshold.” 

In addition to a strong ramp of 400GbE, Crehan’s report predicts that: 

  • 400GbE data center switches will offer a bandwidth discount over lower speed switches during the initial year of shipments
  • 400GbE adoption will be further bolstered by the arrival of 100G-PAM4 SerDes, likely in the 2020 timeframe, thus reducing the number of lanes required to achieve 400GbE by half – from 8*50 to 4*100 – and further lessening the cost and power of these data center switches
  • 100GbE shipments will surpass 40GbE shipments during 2018, just three years after the initial shipments of high-density 100GbE data center switch systems
  • The overall market average selling price per port for data center switching will remain relatively stable, driven by the adoption of higher-speed switches

Renewed growth in servers and Ethernet switching

There are renewed signs of strength in several key industry segments, including servers and switches.
You might think that all of the action is concentrated in public clouds and that the only vendors benefitting from this shift are white box vendors from Asia. But that is not what the Q3 2017 data shows. Certainly, the public cloud is growing by leaps and bounds and ODMs from China and Taiwan are shipping in ever greater volume.
However, a few of the top name brand server vendors, especially Dell, IBM and Cisco (to a lesser extent) are finding renewed growth beyond the handful of hyperscale public cloud projects. This seems to indicate that large corporate data centers are entering a refresh cycle. Intel continues to dominate this sector. Demand for x86 servers increased 20.4% in 3Q17 with $15.4 billion in revenues. Non-x86 servers grew 15.1% year over year to $1.5 billion.
IDC finds that vendor revenue in the worldwide server market increased 19.9% year over year to $17.0 billion in 3Q17.

IDC's Worldwide Quarterly Server Tracker, November 2017

It is good to see this growth is shared by major geographies. IDC breaks down the growth rate as follows:
Server shipment revenue growth (yoy)
·         Asia/Pacific (excluding Japan and China) +30.6%
·         China +23.9%
·         Japan +8.5%
·         U.S. +19.7%
·         EMEA + 19.5%
·         Canada +14.5%
·         Latin America +2.4%.
Servers require switches, so it is not surprising to see this market segment growing in step with the server shipments.

Dell’Oro Group recently reported that Ethernet Switch – Layer 2+3 market revenue reached an all-time record in 3Q17, posting the highest year-over-year growth in five years. The positive results were driven by both campus switching and data centre switching. Cisco did will with its new Catalyst 9K switches and Intent-based networking paradigm. Arista did exceptionally well as evidenced by its most current quarterly financial report and despite the ongoing legal battle with Cisco.

“We are starting to see signs for recovery in the Campus Switching market,” said Sameh Boujelbene, Senior Director at Dell’Oro Group. “Softness in campus switching has been weighing on the Ethernet Switch market over the past two years. It has been outweighing strength in Data Center switching until now as Cisco and HPE captured most of the growth in North American and European campus switching markets during the quarter, while Chinese market remained dominated by Huawei and H3C,” stated Boujelbene.

IDC also reported a strong Q3 for the worldwide Ethernet switch market (Layer 2/3). The IDC figures show $6.75 billion in revenue in the third quarter of 2017 (3Q17), an increase of 7.4% year over year.
