…against Ethernet port failure and link failure between an adjacent pair of Ethernet ports, where the individual member links of a Link Aggregation Group (LAG) are physically routed over separate and diverse paths. To provide Ethernet resilience against forwarding failures, a set of Spanning Tree Protocols…

…management aspect of SLA failures. SLA failures can be caused by link failures, such as a failing optical transceiver resulting in partial packet loss, or a service transport failure, such as a software failure leading to incorrect forwarding tables. Fault Notification Once detected by the network element…

…Radio Access Network (RAN) transport. The packet-bound IWF packetizes and encapsulates TDM data into either Ethernet frames or pseudowires, and forwards the data to the metro Ethernet or IP/MPLS packet network. The TDM-bound IWF extracts TDM data from the pseudowires or Ethernet frames and recreates…

…routers lose service transparency. This loss is a result of the users-' inability to access SONET/SDH overhead bytes, the Data Communications Channel (DCC) that carries all the management bytes, and the inter-nodal communications used to determine network paths and link states. A traditional SONET/SDH solution…
