摘要： A system for switching variable size packets in a network is disclosed. The system comprises at least one ingress controller which receives a plurality of packets and which segments each of the packets into fixed sized fragments. The at least one ingress controller has a time-clock. The time clocks of all ingress controllers are synchronized to within a tolerance. Each fragment is tagged with at least a unique source of ID, time-stamp, and a fragment-number to form a cell. Each cell belongs to one packet having the same time-stamp value. The ingress controller sends each of the cells through a link such that a cell's destination is reachable through that link. The system includes a fabric element which receives cells from a plurality of inputs links. The cells are ordered. The fabric element sends ordered cells through a plurality of outputs and through which the destination of the cells is reachable. The cell order is defined such that a cell ahead of another either has a lagging time stamp, or if the timestamp is the same the cell ahead of another has a source-id which has a predetermined priority, or if both the timestamp and the source-id are the same the cell ahead of another has a lagging fragment-number. The system finally includes at least one egress controller which receives the ordered cells from the plurality of input links, and sends the ordered cells through an output where such order results in complete packets. A packet switching device in accordance with the present invention solves the cell ordering and packet reassembly issues using a unified distributed method in a multi-stage interconnect network.

摘要： A method and apparatus for more efficient routing of packets in a network is provided. The apparatus may include dynamic routing of packets or portions of packets which avoids congestion and blocking by making local decisions within the network. The apparatus may further include creating and updating routing tables which map switch outputs to available network output ports. Additionally the header of packets entering the network are processed prior to entry or as part of the entry to the network to produce a processed packet. The processed packets or portions of packets preferably include complete route information or a final destination address that enables rapid routing through the network without further processing of the packet header. One or more aspects of the inventions may be implemented in combination with other aspects of the invention to further improve network efficiency.

摘要： Methods and apparatus that reduce the error rate of a Serial-De-Serial (SerDes) backplane connection are shown. The apparatus may include a receiver verifying a received block of data at the PHY layer. When the received block of data is received correctly, that block can be acknowledged by the receiver to the transmitter, which is also located at the PHY later. Upon detection of an error in a block of data, the receiver may send a negative acknowledge along with the block number, or some other suitable block identifier, of the faulty block to the transmitter. The transmitter may buffer blocks of data, and remove each block from the buffer upon receiving an acknowledgement. Use of the retransmission protocol may be triggered by speed of the connection, the bandwidth of the connection, the detection of too many errors in the connection or any suitable combination of these, or other, parameters.

摘要： A method and system for managing memory in a packet switching device is disclosed. The method and system comprises managing the memory as a single FIFO when inserting packets and managing the memory as a plurality of FIFO queues when removing packets. A memory management scheme in accordance with the present invention takes advantage of the nature of packet switching to give an efficient implementation of multiple independent queues in a memory. The key observation that is made is that in a packet switch it is expected that packets may be stored in the memory for a time no greater than the time it takes to fill up the memory. If a packet due to extreme congestion is delayed longer than that, then deleting that packet is an acceptable result.
