Feature Article: Enterprise Ethernet WANs

posted Apr 19, 2010, 2:45 PM by Kurt Marko
My recent feature in Processor Magazine provides an overview of Ethernet WAN circuits. Thanks to increasing availability of fiber connections to many business locations and some new standards and technologies sponsored by the Metro Ethernet Forum, Carrier Ethernet is starting to displace legacy WANs for private, branch office circuits and Internet service. Carrier Ethernet offers the scalability, reliability, and SLAs (service-level guarantees) enterprises expect from carrier-class circuits; however, it can provide much higher throughput (up to 1Gbps) for lower cost per bit than legacy WANs. The primary drawback of Carrier Ethernet is limited availability (it generally requires a fiber POP at each office location) and immaturity (the service is relatively new, rapidly evolving, and growing)
