Binomial Congestion Controls

Binomial congestion controls are a new family of congestion control
algorithms motivated in part by the requirement for new congestion
control algorithms for streaming multimedia applications on the
Internet. These congestion controls reduce the large oscillations in
the sending rate associated with TCP's AIMD algorithm. For more
details, please see this technical
report.

The current release of CM supports SQRT (a TCP-friendly member of
the binomial congestion control family) algorithm. It is implemented
in cm_bincongctl.c and inherits most of its code from cm_tcpcongctl.c
(the TCP AIMD-style CM default). To use SQRT congestion control, one
needs to choose option "y" for the "Binomial congestion control"
option while doing `make xconfig`. *Enabling binomial congestion
control and TCP/CM makes all connections use binomial controls by
default.* However, an application can control the congestion control
algorithm that it wants to use by calling `cm_setcongalg`,
described in the CM API documentation.
