This document presents a conservative loss recovery algorithm for TCP that is based on the use of the selective acknowledgment (SACK) TCP option. The algorithm presented in this document conforms to the spirit of the current congestion control specification (RFC2581), but allows TCP senders to recover more effectively when multiple segments are lost from a single flight of data.
