IP VPN & Ethernet WAN Services White Paper

This paper provides a brief overview of both IP VPN and Ethernet WAN services, looking at the pros and cons of both, from the perspective of both Service Provider and customer, and then considers some of the challenges facing the Service Provider community, both in meeting increasing customer demands for ‘Wires Only’ Ethernet Access to IP VPNs and in making the transition to the provision of Layer-2 Ethernet WAN services. Not least of these challenges is the ability of the Service Provider to offer strong customer service value to their clients in relation to provisioning and troubleshooting, when local connectivity is almost invariably provided via wholesale ‘tail’ circuits offering little or no management visibility to the Service Provider at the point of hand off from WAN to LAN at the customer’s premises.
