摘要： The present invention provides a high-performance network switch. A digital switch has a plurality of blades coupled to a switching fabric via serial pipes. Serial link technology is used in the switching fabric. Each blade outputs serial data streams with in-band control information in multiple stripes to the switching fabric. The switching fabric includes a plurality of cross points corresponding to the multiple stripes. In one embodiment five stripes and five cross points are used. Each blade has a backplane interface adapter (BIA). One or more integrated bus translators (IBTs) and/or source packet processors are coupled to a BIA. An encoding scheme for packets of data carried in wide striped cells is provided.

摘要： A backplane interface adapter for a high-performance network switch. The backplane interface adapter receives narrow input cells carrying packets of data and outputs wide striped cells to a switching fabric. One traffic processing path through the backplane interface adapter includes deserializer receivers, a traffic sorter, wide cell generators, stripe send queues, a backplane transmit arbitrator, and serializer transmitters. Another traffic processing path through the backplane interface adapter includes deserialize receivers, a stripe interface, stripe receive synchronization queues, a controller, wide/narrow cell translator, destination queues, and serializer transmitters. An encoding scheme for packets of data carried in wide striped cells is provided.

摘要： A system and method for encoding wide striped cells that carry packets of data across stripes. The method encodes an initial block of a first wide striped cell is encoded with initial cell encoding information, and distributes initial bytes of packet data into available space in the initial block of the first wide striped cell. The initial cell encoding information includes control information and state information. One initial block of the first wide striped cell comprises five subblocks corresponding to five stripes. Each subblock includes identical control information and identical state information. The method further includes adding reserve information to available bytes at the end of the initial block of the first wide striped cell. Remaining bytes of packet data are distributed across one or more blocks in the first wide striped cell until an end of packet condition is reached or a maximum cell size is reached. Other steps include encoding the first wide striped cell or another wide striped cell with end of packet information. The end of packet information varies depending upon a set of end of packet conditions, such as, whether the end of packet occurs at the end of an initial block, at the end of the initial block, within a subsequent block, at a block boundary, or at a cell boundary.
