ACCESS TRENDS

A Fitness Program for Ethernet
by Volker Bendzuweit, General Manager, RAD Data Communications GmbH

Designed as a network protocol for LANs, Ethernet today is a rising technology and is slated to be an essential element in Next Generation Networks (NGNs). But one last gap needs to be closed. Ethernet can only become a carrier-grade protocol if it incorporates Operations, Administration and Maintenance (OAM) features of the kind supported by TDM networks. Unlike LANs, service provider networks are large, complex and need to be capable of sustaining large numbers of customers and, not infrequently, several network operators. When offering customers end-to-end services, today's methods of LAN management - based for the most part on protocols like SNMP, ping or traceroute - are not sufficient. What are needed are comprehensive error, network and performance management tools at every network layer. This is the only way that services can be monitored end-to-end and Service Level Agreements (SLAs) verified. Full story
