40 and 100 GbE

Session Abstract

NOTE WELL: This panel discussion spans two time periods. Each panelist will make a brief presentation during the 8:45 to 10:00 session. Part Two will begin 10:15am and be a moderated interactive panel discussion.

This panel discussion will provide an overview of the recommendation of the IEEE High Speed Study Group (HSSG) who have recommended that the IEEE form a Task Force to write a standard for 40G and 100G Ethernet to be called IEEE 802.3ba. This panel discussion will address the distinct market needs and underlying bandwidth drivers between: (a) server edge applications in a data center; and (b) network aggregation applications in carrier networks and large data centers that led to the definition of two data rates for higher-speed Ethernet.

There is divergence in bandwidth growth rates between the two applications, viz. server edge and network aggregation. The server edge bandwidth growth is driven by CPU I/O performance which is following a Moore's Law curve. On the other hand, network aggregation bandwidth requirements are driven by multiple factors such as the increase in access points feeding into the network and higher access data rates. This difference in the bandwidth drivers results in a steeper growth curve for network aggregation applications compared to server applications, thereby leading to the recommendation of different data rates and associated physical interface specifications; 40 GbE for data center server applications and 100 GbE for carrier network aggregation.

A specific objective of the group is to provide appropriate support for the Optical Transport Network (OTN). Possibilities for mapping of 40GbE and, in particular, 100GbE into the OTN will be outlined, together with a discussion for the need to support OTN efficiently, and the resulting benefit to the end user. This session also includes a discussion of several different modulation formats and transmission protocols that may be used in carrier transport networks and the total system capacity resulting from their use.
