Technique for transferring data over a packet switched network |
摘要 |
A technique transfers data over a packet-switched network (PSN), comprising a plurality of intermediate nodes, in a manner that does not require that the intermediate nodes support a network layer infrastructure. A network controller coupled to the intermediate nodes acquires topology information associated with the PSN's topology. This information may include pseudo-wire definitions, ingress and egress interface information, ingress and egress labels, and so on. The network controller generates a transport database from the topology information and distributes the transport database to the intermediate nodes. An intermediate node acquires the transport database information and configures a packet-processing engine (PPE), contained within the intermediate node, to process packets acquired by the intermediate node. |
