MAY 13, 2009 -- Ethos Networks (search Lightwave for Ethos Networks) has announced its new E-240 switch, the latest addition to Ethos' E-series line of purpose-built CET switches, designed to deliver an advanced, comprehensive mobile backhaul transport offering. The E-series products are designed to provide service providers with a standards-based option using traffic engineering to address the resilience, delay, jitter, and synchronization issues service providers face in packet-based mobile backhaul. In addition, the E-240 is designed to enable high aggregation levels of mobile data traffic.
"Ethos Networks' is entering the mobile backhaul market now as many operators and transport backhaul providers are still examining new IP/Ethernet options," said Michael Howard, principal analyst at Infonetics Research. "Carrier Ethernet with QoS and timing/synchronization is the natural growth path from PDH/SDH primarily because it solves the disconnect between fast rising backhaul traffic and flat subscriber ARPU -- but also because Ethernet is standardized, scalable, and operates both at the service and transport layers."
With quality-of-service and traffic engineering capabilities based on standardized Provider Backbone Bridging (PBB) and PBB � Traffic Engineering (PBB-TE), a.k.a. IEEE 802.1ah and 802.1Qay, the E-240 switch is optimized to address Ethernet service delivery with high scalability of up to 240 Gbps coupled with service assurance supporting bound delay and jitter and sub-50-msec restoration. Ethos says the E-240 is one of the industry's first Carrier Ethernet switches to combine IEEE 1588v2 and Synchronous Ethernet based on G.8261 and G.8262 to address timing and synchronization issues found in mobile backhaul. The E-240 was designed from the ground up as a Carrier Ethernet switch to deliver reliable carrier-grade Ethernet connectivity without limitations and the cost of complex routing protocols or the rigidity of legacy systems. The E-240 also offers an integrated hybrid card combining 1- and 10-Gigabit Ethernet for maximum flexibility.
The Ethos E-series is complemented by the Ethos Domain Management System (DMS), a platform for deploying and managing Ethernet services.
