CHICAGO The IEEE Standards Board this week unanimously approved the 802.3ah standard for "Ethernet in the first mile," the Ethernet in the First Mile Alliance (EFMA) announced at Supercomm this week. The approval came the same week as a final approval of 802.17, the Resilient Packet Ring standard.
An original project authorization request (PAR) was approved in July 2001 for the EFM group to work on three areas: point-to-point copper over existing copper plant at 10-Mbit/sec speeds at distances to 750 meters; point-to-point optical fiber at speeds up to 1 Gbit/sec at distances out to 10 km; and point-to-multipoint fiber at the same speeds and distances (passive, or EPON, implementations).
After the original PAR approval, the task force added higher-layer functions for operations, administration, and maintenance to its task list.
Network automation is gaining momentum. Here's how you can drive this powerful technology to its full potential.
Subsea cable alternatives can provide a level of comfort for those concerned about disruptions. Realistically, they will continue to play a small, but critical role in the short term.
Maintaining existing network infrastructures often incurs huge technical debt before newer technologies are adopted over time.
