<DIV><FONT face=Arial size=2>Specifically, one of the work items proposed is:</FONT></DIV>
<DIV><PRE>(1) A congestion control algorithm for less-than-best-effort
"background" transmissions, i.e., an algorithm that attempts
to scavenge otherwise idle bandwidth for its transmissions in
a way that minimizes interference with regular best-effort
traffic. Among the desired features of such an algorithm are
the ability to maintain short standing queues, the capability
to quickly yield to regular best-effort traffic that uses
standard congestion control, the ability to utilize explicit
congestion notification (ECN), active queue management (AQM),
and/or end-to-end differentiated services (DiffServ) where
available, as well as effective operation in today's typical
situations where some or all of these mechanisms are not
available. In addition to specifying a congestion control
algorithm, the work may also include specifications of how such an
algorithm is to be used in specific UDP-based protocols.
(Application of the algorithm to other transport protocols is
expected to occur in the working groups that maintain those
protocols.)</PRE><PRE> </PRE></DIV></BODY></HTML>
