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 (RFC 5681), but allows TCP 
senders to recover more effectively when multiple segments are lost from a 
single flight of data.  This document obsoletes RFC 3517 and describes 
changes from it.  [STANDARDS-TRACK]
