The Future of Cable Business Services 2010: Ramping up Ethernet: Dec. 2, 2010 Connection-Oriented Ethernet Ideal technology for: Mobile/Cell Tower Backhaul High Performance Business Ethernet Services Why ? Guaranteed CIR CIR bandwidth reserved per EVC or CoS CIR-based services unaffected by oversubscribed (EIR) services Consistent QoS Performance EVC traffic traverses pre-determined working or protect path Paths engineered to meet service packet latency & loss requirements High Security COE uses few protocols Fewer protocols = Fewer Security Vulnerabilities 5© Copyright 2010 Fujitsu Network Communications, Inc.
