    摘要： Virtual connection route selection apparatus and techniques are disclosed. At a communication traffic routing apparatus, metric information associated with multiple different routes for a virtual connection, such as a PseudoWire, toward a destination is collected. The metric information may be collected from one or more remote route computation elements capable of computing routes for virtual connections between the routing apparatus and other routing apparatus over an underlying communication system, or during actual establishment of the virtual connections, for example. An initial or re-optimized route for a virtual connection can then be selected at the routing apparatus based on the collected metric information. In some embodiments, although the virtual connection routes are paths computed by Path Computation Elements (PCEs), actual path selection decisions are distributed to routers.

    摘要： A method for testing connectivity of a multi-segment pseudo-wire in a packet switched network, the method comprising: (a) sending an echo request message from a first provider edge device to a second provider edge device for a first segment of the multi-segment pseudo-wire between the first provider edge device and the second provider edge device; and, (b) receiving an echo reply message from the second provider edge device in response to the echo request message, the echo reply message: confirming connectivity of the first segment; indicating whether there is a second segment in the multi-segment pseudo-wire between the second provider edge device and a third provider edge device; and, if there is a second segment, including information pertaining to the second segment.
