Abstract:
1. A method, comprising: evaluating activity associated with a particular attachment circuit during a first threshold interval, wherein if no network traffic is detected over a port associated with the particular attachment circuit during the first threshold interval, then a ping message is sent and a second threshold interval is evaluated for a response to the ping message; determining whether a sign of death (SOD) is indicated on the particular attachment circuit, wherein an out-of-band event is received that is indicative of the particular attachment circuit being terminated; initiating a new network action at an intermediate network node in response to determining that the SOD is indicated on the particular attachment circuit; and receiving configuration data for configuring a plurality of additional attachment circuits at a network interface, and wherein the configuration data is received at a provisioning server that indicates participating provider edge nodes in a provider network and a respective level of service pertaining to per-hop behavior (PHB) parameters for a plurality of pseudowires that span between the participating provider edge nodes.
