Abstract:
In one embodiment, line cards of packet switching or other network devices are configured for terminating pseudowires. Typically, this includes multiple line cards being configured for terminating a same pseudowire, which allows the corresponding pseudowire traffic to be received by any one of these multiple line cards. Each of these pseudowire-terminating line cards is typically configured to apply one or more features to a pseudowire packet. Examples of these features include, but are not limited to: Access Control List, Quality of Service, Netflow, and Lawful Intercept. For a received packet to be sent out one of these pseudowires, a two-stage lookup operation can be used to first identify the pseudowire over which to forward the packet; and a second lookup operation based on the pseudowire to identify forwarding information corresponding to a path through a network over which a corresponding pseudowire is configured.
