10G-EPON standard ratified

PISCATAWAY, USA: Over 40 companies and organizations that supported or participated in the IEEE P802.3av 10 Gb/s Ethernet Passive Optical Network (10G-EPON) Task Force are celebrating completion of IEEE Std. 802.3avTM-2009, also known as Physical Layer Specifications and Management Parameters for 10 Gb/s Passive Optical Networks. IEEE Std. 802.3av and its predecessor, IEEE Std. 802.3ahTM-2004, are specifications that describe Fiber-To-The-Home (FTTH) telecommunications systems.

The following companies have expressed their support for the approved standard: Alloptic, Anritsu Company, ARRIS, B-DeltaCom, Bright House Networks, Cambridge Industries Group, China Mobile Communications Corporation, China Telecom – STTRI, China Unicom – Beijing, Corecess, Cortina Systems, CyOptics, Dasan Networks, Dongwon, Enablence Technologies, ETRI, FiberHome, Fujitsu, H3C, Hisense Broadband, Hitachi, Huawei Technologies, Kawasaki Microelectronics, KDDI R&D, KT, Ligent Photonics, Mitsubishi Electric, NEC, NTT Corporation, OF Networks, OneChip Photonics, PMC-Sierra, Shanghai Luster Teraband Photonics Co., Sumitomo Electric, Teknovus, Telekom Malaysia R&D, Ubiquoss, Vitesse Semiconductor, and ZTE. The China Communications Standards Association (CCSA), the Ethernet Alliance, the Optical Access (FTTx) Industry Alliance (OAIA) of China, and the Taiwan Optical Communication Industry Alliance also endorse the 10G-EPON standard.

The IEEE Std. 802.3av 10G-EPON standard supports symmetric and asymmetric line-rate operations. The symmetric option operates at 10 Gb/s in both the downstream and upstream directions. The asymmetric option, which reflects the fact that IP video services create bandwidth pressure mostly in the downstream direction, uses 10 Gb/s downstream and 1 Gb/s upstream.

IEEE Std. 802.3ah 1 Gb/s EPON (1G-EPON) systems have been deployed to more than 30 million subscribers worldwide and support diverse services, including IPTV, VoIP, and cellular backhaul.

Given the large and accelerating deployment of 1G-EPON systems, the IEEE Std. 802.3av enables seamless upgrades via the simultaneous operation of 1 Gb/s and 10 Gb/s symmetric and asymmetric EPON systems on the same outside plant. This allows operators to introduce 10G-EPON without replacing any existing 1G-EPON customer equipment and minimizes the operational impact of upgrading a large, in-service FTTH network.

Initial deployments of the 10G-EPON equipment are expected in 2010.

First draft for IEEE P1901 broadband over power lines created

PISCATAWAY, USA: The IEEE P1901 Working Group has agreed to circulate for approval the first draft for IEEE's first PHY/MAC standard related to Broadband Over Power Lines (BPL), IEEE Std 1901™, "Draft Standard for Broadband over Power Line Networks: Medium Access Control and Physical Layer Specifications."

At the recent meeting in Tokyo, Japan, the Working Group has agreed with more than 82 percent majority vote to convert the working specifications into the first IEEE P1901 BPL draft standard and to conduct a vote on whether the Draft is ready to go to Sponsor Ballot. Votes and comments are due by September 14.

"This is a major milestone," says Jean-Philippe Faure, chair of the IEEE P1901 Working Group. "Main development is completed and finalization now starts through successive rounds of circulations for vote and comment."

The draft is based on field proven technologies using FTT and Wavelet OFDM modulation schemes. It provides high performance and robust communications with privacy and high quality of service.

"This is a comprehensive specification that addresses all BPL applications including LANs, Smart Grid networks and Broadband access," says Faure. "The draft fully meets the over 400 technical requirements developed by the experts in these areas. The coexistence and interoperability part ensures all equipment and devices used on BPL networks are compatible." The draft also provides seamless integration with other communication media, such as Wi-Fi and Ethernet.

The Working Group will next meet in Boston, Mass., on 13-16 October 2009.

IEEE P1901™ is sponsored by the Standards Committee of the IEEE Communications Society.

IEEE ratifies 802.1Qay (PBB-TE)

PISCATAWAY, USA: The IEEE announced that it has ratified IEEE 802.1Qay™, the industry’'s first packet-based connection-oriented Ethernet technology for next-generation service provider transport networks.

By adapting Ethernet technology to the role of providing carrier-class packet transport networks, IEEE 802.1Qay incorporates determinism and resiliency, helping to improve the ability of service providers to deliver the cost-effective, high-bandwidth multimedia services that today’s enterprise and residential customers are demanding.

The IEEE 802.1Qay standard, "IEEE Standard for Local and Metropolitan Area Networks--Virtual Bridged Local Area Networks--Amendment: Provider Backbone Bridge Traffic Engineering," is based on the existing IEEE 802.1ah standard for Provider Backbone Bridging (PBB).

IEEE 802.1Qay defines Provider Backbone Bridge Traffic Engineering (PBB-TE), a technology that helps enable service providers to explicitly set up traffic engineered paths across a Carrier Ethernet Network. Unlike prior packet-based Ethernet, PBB-TE uses an external management plane for determining and deploying the traffic engineered paths.

This approach simplifies the operational requirements of each network element and is consistent with current transport crafts and practices, enabling a smooth migration to next-generation transport networks.

“The ratification of IEEE 802.1Qay is an important milestone for the telecom industry, as service providers now have an approved standard for packet-based Connection-Oriented Ethernet technology and they can confidently proceed today with their IP network transformation programs,” said Tony Jeffree, Chair of the IEEE 802.1 Working Group.

“On behalf of the IEEE, I’d like to thank the 802.1 Interworking Task Group for its hard work and dedication and congratulate each member on this impressive achievement.”

“By completing the standardization of 802.1Qay, the IEEE is presenting service providers with a key capability that compliments the existing PBB standard and supports the organic growth of Ethernet in access and aggregation metro networks,” said Sterling Perrin, senior analyst at Heavy Reading. “A lack of standardization is always an inhibitor to mass deployment of a technology by service providers. The standardization of both PBB and PBB-TE now remove this barrier and I expect we’ll see increased and renewed interest in PBB-TE as a transport technology.”

Provisions for MAC/PHY and Inter-System Protocol approved

PISCATAWAY, USA: The IEEE working group devoted to developing a standard for Broadband over Power Lines (BPL) met in Las Vegas in May, where it devoted its attention to the work of its technical subgroups.

The working group is developing a new standard, IEEE P1901, "Standard for Broadband over Power Line Networks: Medium Access Control and Physical Layer Specifications." When completed, the project will present a standard for high speed (>100 Mbps at the physical layer) communication devices via alternating current electric power lines, so-called Broadband over Power Line (BPL) devices.

Technical Subgroup 2 (TSG2), which is dedicated to FFT and Wavelet MAC/PHY, presented thirteen revised chapters of the draft Standard on MAC/PHY layers and security.

Technical Subgroup 4 (TSG4), which is dedicated to coexistence, presented a draft annex describing the Inter-System Protocol (ISP) that enables various BPL devices and systems to share communication resources (frequency/time) when installed in a network with common electrical wiring.

ISP will allow P1901-compliant devices and ITU-T G.hn-compliant devices to co-exist. The protocol provides configurable frequency division for Access and time division for in-home with a granularity compatible with the Quality of Service (QoS) requirements of the most demanding audio and video applications.

The Working Group approved TSG2's revisions by an 83 percent majority, and unanimously approved TSG4's ISP annex.

The technical subgroups continue to hold weekly teleconferences as they further develop the first official draft of the P1901 standard. TSG2 will also hold a face-to-face meeting during the week of 15-19 June in Fukuoka, Japan.
