TECHNIQUE FOR MULTIPLE PATH FORWARDING OF LABEL-SWITCHED DATA TRAFFIC |
摘要 |
A technique for multiple path forwarding of label-switched data traffic in a communication network across multiple paths such that traffic associated with a particular label-switched path (LSP) is forwarded on the same path in the network. An incoming label associated with a packet is used to select an Equal Cost Multiple. Path (ECMP) technique that is used to identify an interface among a plurality of interfaces on which the packet may be forwarded. An incoming label associated with the packet is used to identify an outgoing label for the packet as well as the plurality of interfaces on which the packet may be forwarded. A label in the packet's label stack is hashed to produce a hash value. The hash value is then used to identify an interface from the plurality of interfaces on which the packet is forwarded. The outgoing label is placed in the packet and the packet is forwarded on the identified interface. |
