Carriers strike gold with Ethernet as bells start to toll for SONET/SDH…
A new study of 27 top tier service providers in North America, Every service provider interviewed in the Infonetics Research study, ‘Service Provider Plans for Metro Optical and Ethernet’, already offers Ethernet services, and their metro Ethernet service revenue is growing fast. “The most telling finding in the study is that the vast majority of service providers we interviewed have a strategy for using Ethernet instead of SONET/SDH for accessing and collecting customer traffic,” says Michael Howard, principal analyst of Infonetics Research and lead author of the study. “Ethernet as a carrier class technology has made considerable progress; almost 90% of service providers participating in the study believe Ethernet is mature for carrier class deployments, which is much different from the attitude of two years ago.” Other highlights from the Infonetics analysis include: · more than a fifth of service providers interviewed have stopped deployment and over half have slowed deployment of new SONET/SDH gear in their access networks · Ethernet transport tunnels will be an essential ingredient of the services and optical transport layers; T-MPLS and PBT, both very new technologies, show good growth as VPNs by 2008; over a quarter consider Ethernet tunneling protocols a critical feature on metro Ethernet equipment they will purchase in 2008 · the percent of service providers offering Ethernet over WDM for metro Ethernet services increases from 70% in 2007 to 85% after 2008, while the number offering Ethernet over SONET/SDH decreases from 93% to 78% · two-thirds have deployed hybrid products with Ethernet, WDM, and SONET/SDH in a single chassis, used to migrate to packet optical transport According to optical burst switching pioneer Matisse Networks, which has just announced that it has closed a US$45mn Series C financing round to expand the sales, marketing and development of its EtherBurst optical switch, the worldwide installed base of over 400,000 SONET/SDH optical rings is incapable of meeting the bandwidth demand for packet services created by both consumers’ appetite for high bandwidth applications such as Internet Protocol Television (IPTV), and enterprises’ migration to high speed Carrier Ethernet services. For IP and Ethernet transport, these legacy SONET/SDH networks cost far more to deploy and maintain than newer Ethernet over wave division multiplexing (WDM) solutions such as Matisses' EtherBurst optical switch. Matisse also quotes Infonetics’ Howard: “Around the globe, carrier investment in optical networking equipment is clearly beginning to shift from SONET/SDH to Ethernet over WDM. Matisse Networks' innovative EtherBurst optical switch is well suited to serve a worldwide metro WDM market segment forecast to grow at a 19% compound annual growth rate to US$4.0bn through 2010.” John Williamson |
