METHOD AND APPARATUS FOR ADJUSTMENT OF TCP SLIDING WINDOW WITH INFORMATION ABOUT NETWORK CONDITIONS

摘要

A method and apparatus for adjustment of TCP sliding window. Network and traffic information is obtained. This information is used to control the transmission of the TCP source without any modifications to the existing TCP sources. Feedback information is received in an acknowledgment packet, a packet having an advertised window field set to an original advertised window size for a sliding window is received, and the advertised window field is modified to choose the size of the sliding window in response to feedback information. The original advertised window size indicates the original size of a sliding window for determining a number of bytes that can be sent before an acknowledgement packet is received. The feedback information includes a window advertisement. The window advertisement specifies an increase to the size of the sliding window, which includes the minimum of the window advertisement and a congestion window.
