摘要： The present invention is a system and method for forwarding packets in order. A first packet may be received for forwarding. Subsequently, a second packet may be received for forwarding. A first memory request corresponding to the first packet is sent. A second memory request corresponding to the second packet may be sent prior to receiving a first memory reply corresponding to the first memory request. The first packet is forwarded prior to forwarding the second packet. In this novel manner, bandwidth in a network apparatus may be utilized with greater efficiency while maintaining packet ordering.

摘要： A method and system thereof for forwarding data packets according to an order of forwarding while lessening delays. A resource request corresponding to a first data packet that is first according to the order is generated. A first resource request corresponding to a second data packet that follows the first data packet according to the order is generated. Generation of a subsequent resource request for the second data packet is delayed for a specified time period. A second resource request for the second data packet is generated before the specified time period is due to expire when the first data packet is forwarded. In this manner, a delay attributable to the specified time period is lessened.

摘要： A method for generating a modified packet for output from a router. First, a received packet is stored in one memory location. Modified bytes corresponding to the received packet are computed and stored in a separate memory location. The modified packet is generated by multiplexing between select unmodified bytes of the received packet with the modified bytes.

摘要： A system for forwarding packets. The system has a first node for creating requests that contain a number of filters for specifying packet forwarding criteria. The first node also specifies values for the filters based on a packet to be forwarded. The system also has a second node coupled to the first node and to a number of ports. The second node has at least one table for specifying which of the ports are to receive the packet based on the filter values. The second node determines which of the ports are to receive the packet based on the table information and the filter values.

摘要： A system and method for reconfiguring a TCP window in a switch of a network system, where the size of the window is determined based on the operating speed of a work station to which data packets in the window are being sent and the size of the switch buffer. The algorithm includes establishing a connection between a server and the station, where the connection includes TCP data packets. The algorithm identifies a TCP window size requested by the station, and identifies the connection speed of the station in the switch. The algorithm then modifies the TCP window size of the connection if the identified TCP window size does not support the connection speed and the size of the buffer. The algorithm also changes the TCP check-sum based on the new TCP window size.
