摘要： A novel approach is provided for avoiding the “slow-start restart” in TCP communications when network conditions dictate such. The disclosed approach serves to overcome the latency related to the “slow-start restart” by assessing network conditions and avoiding the “slow-start restart” when network conditions justify the avoidance. The disclosed methods, applications and devices implement the periodic communication of a probe packet that is generated and transmitted from a TCP sender to a TCP receiver during the period that the TCP network connection remains idle. Receipt of the probe packet by the TCP receiver will trigger transmission of an acknowledgment message by the TCP receiver. Upon receipt of the acknowledgement message the TCP sender will restart measurement of the idleness period and, as such the “slow-start restart” is avoided.

摘要： A system and method are provided for requesting a resource over at least one network. The system includes a terminal, a host and a network proxy. The terminal can send a first request for the resource over a first network and a second network. In turn, the host can receive the first request and send a first response, where the first request identifies the resource at a first location on the host. The network proxy, which can communicate with the host over the second network independent of the first network, can receive the first response from the host, and reformulate the first request into a second request that identifies the resource at a second location. The network proxy can send the second request to a host of the resource at the second location such that the host of the resource at the second location can respond to the second request.

摘要： A method and apparatus for coupling IP ECN with ATM congestion control is disclosed. The invention extends IP-ECN to ATM devices with minimal implementation complexity. Thus, the performance of IP data traffic over ATM is enhanced without requiring packet-reconstruction at the ATM layer. The method includes using AAL5 packet trailers in ATM cells to detect packet boundaries for identifying a first cell in an IP packet, determining whether an ATM cell capable of using explicit congestion notification to indicate congestion and setting a explicit congestion notification indicator in a capable ATM cell to indicated congestion to a source node. The use of the packet trailers further comprises monitoring a flag for indicating whether an ATM cell is an end of packet. The method further includes resetting the end of packet flag to an off state to so the next cell is recognized a first cell of a packet and transmitting the ATM cell. A determination is made as to whether a next ATM cell is a first ATM cell for a packet. The next ATM cell is transmitted when the ATM cell is not a first ATM cell for a packet. A determination is then made as to whether ATM congestion is associated with the next ATM cell. The next ATM cell is then transmitted when congestion is not associated with the next ATM cell.

摘要： A peer-to-peer communication system for resolving dynamic channel assignment conflict in a channel assignment in a AAL2 negotiation procedure. The peer-to-peer communication system includes at least one pair of peer entities connectable by a channel having a channel identification, one peer entity of the pair of peer entities having a higher priority status than the other peer entity. When one peer entity of the pair of peer entities requests a same channel as the other peer entity, the channel is assigned to one peer entity which has the higher priority status. The higher priority status is alternated between the pair of the peer entities after each channel conflict.
