摘要： A plurality of network characteristics of a wireless network are determined and a plurality of TCP session parameters are updated. The network characteristics may be determined based at least in part on a comparison of the estimated bandwidth and estimated propagation delay of the wireless network and the typical bandwidths and propagation delays of one or more wireless networks. The TCP session parameters may be updated based at least in part on the network characteristics. The TCP session parameters may be used to limit the congestion window, retransmission timeout and slow start threshold.

摘要： A retransmission timer of a Transmission Control Protocol (TCP) session is set based at least in part on the predicted mean round trip time differential of the TCP session. For example, in one embodiment, after receiving a non-duplicate acknowledgment, the predicted mean round trip time differential of the TCP session would be determined and used to further determine the predicted round trip time of the next transmitted data segment. In one embodiment, the predicted round trip time of the next transmitted data segment would be used to determine a retransmission timeout, the value of which would be inserted into a retransmission timer.
摘要翻译：至少部分地基于TCP会话的预测的平均往返时间差来设置传输控制协议（TCP）会话的重传定时器。例如，在一个实施例中，在接收到非重复确认之后，将确定TCP会话的预测平均往返时间差，并用于进一步确定下一个发送数据段的预测往返时间。在一个实施例中，下一个发送的数据段的预测往返时间将用于确定重传超时，其值将被插入到重传定时器中。

摘要： During a Transmission Control Protocol (TCP) session, a congestion window and slow start threshold may be limited to a range defined by a minimum congestion window and a maximum congestion window based at least in part on the network type of a wireless network. The network type of a wireless network may be determined based in part on one or more round trip times of one or more data segments and one or more TCP session parameters are set to corresponding stored session parameters that are associated with the network type.

摘要： There is provided a system and method for providing a simple yet flexible overlay network on top of any IP networks to enable diverse network applications whereby much of the rigidities of IP protocol suite are eliminated without any modifications to the applications. In particular, the system includes: a plurality of c-nodes; one or more source terminal nodes connected to an IP network; and one or more destination terminal nodes connected to the IP network. Here, the source terminal nodes send IP packets over the plurality of c-nodes to the destination terminal nodes to accomplish arbitrary communications between arbitrary groups of the source terminal nodes to arbitrary groups of the destination terminal nodes. More specifically, a method employing the system utilizes the concept of connection ID and headers that can be inserted anywhere in the IP packet.

摘要： There is provided a method of delivering a plurality of source streams from a plurality of servers to a plurality of clients through a plurality of routers over a communication network using a pay-per-period pricing scheme. Said method includes: splitting the source stream into a plurality of sub-streams to the routers; estimating available capacities of the plurality of the routers; and delivering the sub-streams to the routers at transmission rates proportional to the available capacities of the routers. The available capacity is estimated based on input and output traffic correlations in the server. Further, the client, who is not an owner of the available capacity, may be allowed to use the available capacity at a lower priority than that of the owner. The delivery of the source stream may be carried out over a plurality of paths over the communication network, wherein time-space trajectories of the paths do not cross each other. The method of the present invention provides a large-scale optimal exploitation of available capacities such as network bandwidths and computing resources for content delivery, while ensuring high QoS of content delivery.
