    摘要: In network systems for transporting GFP-encapsulated FICON frames across a SONET/SDH transport network between FICON ports, the transport interfaces for the FICON ports operate to drop duplicate and out-of-order frames transported across the SONET/SDH network. The transmitting transport interface inserts a sequence number incremented with each FICON frame into said one or more transport frames, whereby the sequence number is used as an index for determining duplicate and out-of-order frames after transport over said SONET/SDH network. The receiving transport interface compares sequence numbers with each FICON frame to determine duplicate and out-of-order FICON frames, drops the duplicate and out-of-order FICON frames; and sends the balance of the compared FICON frames to the receiving FICON port.

    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.
