    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.

    摘要: A packet communications network includes a route management system in which routes can be remotely changed by using a simple set command to set a data value in the originating or terminating node of the route. Storage tables in the originating and destination nodes record the route changes and administrative data concerning the route. This administrative data can be retrieved from the originating node by simple get or get-next commands. The administrative data can include the specific specification of the route in links, the time of creation of the route, the route replaced and the reason for initiating the change in route. Together these capabilities permit centralized management of route changes in the entire network from a single manager node, and using only simple set, get and get-next command structures.
