    摘要: A method includes receiving a request to provision a path associated with at least a portion of a packet network and determining whether a router is associated with the path in the packet network. The method also includes provisioning a first connection between a first gateway and a second gateway when the router is not associated with the path. The method further includes provisioning a second connection between the first gateway and the router and a third connection between the router and the second gateway when the router is associated with the path. In addition, the method includes at least one of associating and disassociating a first endpoint of the first gateway and a second endpoint of the second gateway with one or more of the connections.

    摘要: The disclosure presents techniques for merging multiple data flows in a network such as a Passive Optical Network (PON). The PON comprises an interface module and network nodes connected to the interface module via an optical fiber link. Each network node further serves client devices. The client devices request multiple data flows, requiring the interface module to serve multiple data flows to a network node for delivery to the devices. The interface module merges received data flows to permit multiple flows to be processed by a single segmentation and reassembly (SAR) engine, reducing hardware cost and complexity within the node. However, subunits associated with different data flows within a merged data flow are not interleaved with one another. Instead, the subunits associated with an original unit of information are transmitted contiguously within the merged data flow, facilitating identification and reassembly of the subunits for a particular microflow.

In the node apparatus, a packet segmented into cells and arriving from each input VC is temporarily stored in a packet queue (26) corresponding to each input VC. When the final cell of the packet arrives, 1-packet cells are moved altogether to an output queue (27) corresponding to the destination IP address contained in the start cell and output to a corresponding output VC by an output section (28).

    摘要: A network router where fragmentation takes place prior to the queuing. After packets are classified, the low priority packets are fragmented and AAL5 and MLPPP encapsulated. The fragments and the high priority packets are PPP encapsulated. Next the packets are queued using an MDRR queuing. All fragments for each packets are placed in the same queue. At the output of the queue, sequence numbers are added to the fragments of each packet. Finally the packets are queued for transmission.

    摘要: A multi-service segmentation and reassembly (MS-SAR) integrated circuit is disposed on a line card in a router or switch. The MS-SAR can operate in an ingress mode so that it receives packet and/or cell format data and forwards that data to either a packet-based or a cell-based switch fabric. The MS-SAR can also operate in an egress mode so that it receives data from either a packet-based or a cell-based switch fabric and outputs that data in packet and/or cell format. The MS-SAR has a data path through which many flows of different traffic types are processed simultaneously. Each flow is processed by functional blocks along the data path in accordance with one of several application types, the application type for a flow being predetermined by the host processor of the router or switch. Segmentation, reassembly and partitioning techniques are disclosed that reduce costs and facilitate high-speed operation.
