Abstract

Ethernet as a transport technology has, up to now, lacked the features such as network layer architecture, customer separation and manageability that carriers require for wide-scale deployment.However, with the advent of PBB-TE and T-MPLS, it is now possible to use Ethernet as a transport technology, making the use of Ethernet as a convergence layer for Next Generation Networks a distinct possibility.Triple Play services, in particular IPTV, are expected to be a main drivers for carrier Ethernet, however, a number of challenges must be addressed including QoS enabled control plane, enhanced OAM functions and survivability.This article provides an overview of PBB-TE and T-MPLS and demonstrates how IPTV services can be realized in the framework of Carrier Ethernet.
