Auto-detection of limiting factors in a tcp connection

摘要: This invention comprises auto-diagnosis logic that can be implemented in operating systems an appliance-like module coupled to the TCP receiver, sender or both. events are sampled and a set of statistics on these is maintained. Receiver side (205) diagnostic techniques include detecting sender's re-transmission timeouts, evaluating average size packets being received (230), determining if receiver bottleneck,and performing other evaluations (235) incoming data stream. Sender flagging transmission monitoring transmitted packet, advertised window accounts for delay-bandwidth product network connecting systems, bottleneck checks, outgoing The results aggregated using system attributes. Systems with common problem areas attributes grouped together. performed on-line off-line.
