This tutorial addresses how Carrier Ethernet technologies can be used in the transport network to provide resilience to the packet layer. Carrier Ethernet networks based on PBB-TE and T-MPLS/MPLS-TP are strong candidates for reliable transport of triple-play services. These technologies offer Operation, Administration and Management (OAM) functionalities and support for Quality of Service (QoS), required to obtain carrier grade quality. This tutorial provides an overview of the current level of standardization followed by an exhaustive survey of Carrier Ethernet reliability. A number of enhancements are still required to make Carrier Ethernet ready for large scale deployments of reliable point-to-multipoint services. The tutorial highlights the necessary enhancements and shows possible solutions and directions towards reliable multicast. Explicit focus is on OAM for multicast, where the signalling to identify faults is described. Finally, best practises from a Danish National project are shown.
