Review on the Operation, Administration and Maintenance (OAM) of BcN
Kyung Chun, Jongtae Song, Soon Kyu Lee · 2006
The BcN architecture of VPWS is introduced as a service model. The network elements forming the BcN data plane and a centralized controller forming the BcN control plane functionality are briefly described. A mapping architecture which transports the VPWS signal is presented. We examine the propagation of the maintenance signal under the network failure condition. The main purpose of this architecture is to find out the relationship between the maintenance signals in each layer. Finally, we briefly review the MPLS OAM ITU-T Rec. Y.1711 and Ethernet OAM being recommended in ITU-T Rec. Y.1731
