Windows TCP窗口缩放过早达到高原(3)

To better utilize the bandwidth of TCP connections in these
situations,the Next Generation TCP/IP stack includes Compound TCP
(CTCP). CTCP more aggressively increases the send window for
connections with large receive window sizes and large bandwidth-delay
products. CTCP attempts to maximize throughput on these types of
connections by monitoring delay variations and losses. CTCP also
ensures that its behavior does not negatively impact other TCP
connections.

In testing performed internally at Microsoft,large file backup times were reduced by almost half for a 1 Gbps connection with a 50ms RTT. Connections with a larger bandwidth delay product can have even better performance. CTCP and Receive Window Auto-Tuning work together for increased link utilization and can result in substantial performance gains for large bandwidth-delay product connections.
