This report analyzes 40/100-Gbit/s technologies, identifying the key advantages they hold for equipment manufacturers. It also surveys component availability, and profiles leading vendors in this growing market. The report also profiles 17 providers and how they are addressing the rising 40/100-Gbit/s technologies.

概要

Ethernet is replacing synchronous optical networking (Sonet)/synchronous digital hierarchy (SDH) and Fibre Channel across the network from the data center, through the access network and into the metro and core network. The continued push for bandwidth in the access network is causing bottlenecks in long-haul trunk routes. So far, these bottlenecks have been eased with the use of point-to-point 40-Gbit/s and higher rate links using DWDM transport systems. In data centers, many servers now support multiple Gigabit Ethernet links, and some have dedicated 10GE interfaces. Aggregation within the data center and, in some cases, transportation between data centers now require 40-Gbit/s links as well.

As the use of high-bandwidth links increases, these interfaces must be integrated into other networking equipment, reducing the cost but also increasing the need for standardization in a market where performance and differentiation are key to success. Several vendors are now introducing 300-pin modules in conjunction with their DWDM transport systems, and interest in interoperable solutions is growing.

With 10GE now well developed and the cost of interfaces falling, there is a renewed effort in the development of 40/100-Gbit/s Ethernet. The first components and systems with support for 40-Gbit/s Ethernet will possibly be available in 2009. Infiniband is an alternative solution for the data center, and it continues to grow in market share. The first Infiniband systems supporting 40-Gbit/s node-to-node links are expected to begin shipping before the end of this year.

This report details and analyzes 40/100-Gbit/s technologies, identifying the key advantages they hold for equipment manufacturers. It also surveys component availability, and profiles leading vendors in this growing market. The cost of 40-Gbit/s interfaces is also falling, with semiconductor and optical component vendors introducing new products that deliver better performance and greater integration. Vendors must position themselves and agree on common form factors and electrical specifications because 100-Gbit/s interfaces are on the horizon. This is a demanding market with high development costs, and few vendors can offer complete solutions across the varied technologies.

40-Gbit/s Technologies: Lower Costs Will Drive New Demand provides critical data and analysis for a range of industry participants, including:

			Suppliers of 40-Gbit/s Ethernet solutions who need independent analysis of expected market demand for their products as well as deeper insight into buyer plans for product deployments
			Telecom equipment vendors looking for quantitative assessments of how their competitors will be using 40-Gbit/s and 100-Gbit/s Ethernet in the coming months and years
			Investors needing a better understanding of the 40/100-GE sector, and which suppliers are best positioned for success

Sample research data from the report is shown in the excerpts below: The IEEE802.3ba task force is working to standardize Ethernet at 40 Gbit/s and 100 Gbit/s. There has been a significant debate on whether both 40 Gbit/s and 100 Gbit/s are required; however, the agreed upon solution is to develop both and let the market decide. There have been some important lessons learned through the development of 10-Gbit/s Ethernet, which are reflected in the objectives set by the IEEE802.3ba PAR approved in December 2007. The main objectives are: Support only full-duplex operation Preserve the 802.3 / Ethernet frame, format utilizing the 802.3 MAC Preserve minimum and maximum frame size of current 802.3 standard Support a BER better than or equal to 10 to 12 at the MAC/PLS service interface Provide appropriate support for OTN Support MAC data rates of 40 Gbit/s and 100 Gbit/s Provide Physical Layer specifications for a range of physical media including fiber, copper, and backplane as shown in the following figure. 拡大図
