Abstract:
This document specifies careful convergence of Congestion Control
(CC), providing a cautious method that enables fast startup for a
wide range of connections or reconnections.
The method reuses a set of computed CC parameters that are based on
the previously observed path characteristics between the same pair of
transport endpoints, such as the bottleneck bandwidth, available
capacity, or the Round Trip Time (RTT). These parameters are stored,
allowing them to be later used to modify the CC behavior of a
subsequent connection. The document also discusses assumptions and
defines requirements around how a sender utilizes these parameters to
provide opportunities for a connection to more quickly get up to
speed (i.e. utilize the available capacity). It discusses how these
changes impact the capacity at a shared network bottleneck and the
safe response that is needed after any indication that the new rate
is inappropriate. The method is expected to be appropriate to IETF
transports.
