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 network element is deployed in a network of interconnected elements. The network element includes a shared buffer multiplexer connected to a link, a set of regulators connected to the shared buffer mulitplexer, and an admission control unit communicatively coupled to the set of regulators and the shared buffer multiplexer. Each of the set of regulators has an input traffic flow. Each traffic flow has a varying flow rate. In order to control admission of the traffic flow to the link in the network element, the admission control unit evaluates the traffic flowing into each regulator. For each traffic flow, the admission control unit receives an envelope of the flow input to the regulator. The admission control unit maximizes the entropy of a distribution of the rate of flow over all time scales. The admission control unit determines the maximum-entropy distribution for the flow using information derived from the traffic envelope, including bounds of the mean rate, the minimum rate, and the maximum rate. The admission control unit approximates the rate variance of the maximum-entropy distribution for a given maximum rate. The admission control unit makes an admission control decision based on the approximated rate variance for the given maximum rate. If the flow is admitted, the flow is set up and transmission begins.

摘要： Method and apparatus for efficient management and transport of traffic over a network. The available bandwidth capacity of paths in a network may be stored in a first router. A request may be received at the first router from a network node of a second network for a signaled path through the network to a destination node. Paths may be examined by the first router and the signaled path assigned to a path from the first router to the destination node using an existing path through the network. Further, all traffic from a subnet to a given destination network may be handled by one or more mobile agents at the subnet. One or more mobile agents may be assigned to all or some of the traffic based on current path loading.

摘要： A method and data structure for preventing the misconcatenation of partial packets when an even number of packets are lost over the network. A channel identifier code is added to the head of a remainder partial packet to allow the remainder partial packet to reassembled with a prior partial packet having the same channel identifier code. The method includes the steps of determining whether each packet will be divided into a first partial packet and a remainder partial packet at an ATM cell boundary, adding a CID at the beginning of each remainder partial packet, assembling the first and remainder partial packets into ATM cells, transmitting the ATM cells, receiving the ATM cells, verifying whether a first partial packet and a remainder partial packet in the received ATM cells have the same CID and assembling the first partial packet and the remainder partial packet into a single packet when the CIDs match. The method may also includes the steps of discarding the first and remainder partial packets when the CIDs do not match or sending the first partial packet to a user identified by the CID for the first partial packet and the remainder partial packet to a user identified by the CID for the remainder partial packet. The CID comprises a one byte code. The data structure for the ATM cell includes a header and a payload assembled to the header, the payload comprising at least one packet, wherein the at least one packet comprises a remainder partial packet having a channel identifier code attached thereto to identify the user for the remainder partial packet.
