FLOW CONTROL BETWEEN PERFORMANCE ENHANCING PROXIES OVER VARIABLE BANDWIDTH SPLIT LINKS

摘要

The invention provides a method and system for dealing with the flow of data between one Performance Enhancement Proxy ("PEPI")and another ("PEPI") in the context of split links for TCP over satellite performance improvement. The environment according to the invention may include one or more intermediate nodes (103, 105) experiencing variable latency and bandwidth allocations. The method and system manage the data flow to ensure bandwidth fairness between competing TCP/IP connections, prevention of PEP receiver buffer overflow and near 100% usage of the available satellite bandwidth without the need for conventional TCP/IP ACK driven probing algorithms. The near 100% usage of capacity being achieved, in part, through PEP to intermediate node message exchange.
