Title: Aggregating Congestion Information Over Sequences of TCP Connections

Abstract: 

In this paper we present an extension of the TCP stack that allows a
sequence of TCP connections between the same machines to
share the congestion window. Our Linux implementation of this
scenario shows significant improvement in performance,
particularly when the individual connections are short-lived. Such a
behavior is common on the web, due to the nature of the HTTP protocol
and the distribution of file sizes.
