摘要： A technique for disguising ATM cells as ATM cell-containing packets within a routing facility to permit the packet-only switch to also handle switching of the ATM cells. The technique has wide applications within the backbone infrastructure, Wide Area Networks, Metro Area Networks, Local Area Networks, and particularly within a routing facility to handle high speed traffic. The technique can receive both ATM cells and packets for switching via a single channel or optical fiber or receive ATM cells and packets via two separate channels or two separate fibers. The ability to handle both ATM cell and packet switching allows packet-only routers to handle ATM traffic, thereby reducing the cost of the switching infrastructure for network operators.

摘要： A method for dynamically allocating bandwidth among ATM cells and packets scheduled for output from an aggregation multiplexer of a transport-layer device configured to multiplex both ATM cells and packets onto the same channel of an optical fiber. The method includes local control and relative priority lookup of incoming ATM cells and packets to support output decision. When compared to currently employed methods, the required level of coordination with the receiving circuit for dynamic bandwidth allocation is substantially lower, thereby reducing operational complexity for network operators and latency for critical data when reallocating bandwidth.

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.
