Abstract:
One of the major advantages of SCTP is the support of multi-homed
communication. A multi-homed SCTP end-point has the ability to
withstand network failures by migrating the traffic from an inactive
network to an active one. However, if the failover operation as
specified in RFC4960 is followed, there can be a significant delay in
the migration to the active destination addresses, thus severely
reducing the effectiveness of the SCTP failover operation.
This document complements RFC4960 by the introduction of a new path
state, the Potentially Failed (PF) path state, and an associated new
failover operation to apply during a network failure. The algorithm
defined is called SCTP Potentially Failed Algorithm, SCTP-PF for
short. In addition, the document complements RFC4960 by introducing
alternative switchover operation modes for the data transfer path
management after the recovery of a failed primary path. These modes
can allow improvements in the performance of the operation in some
network environments. The implementation of the additional
switchover operation modes is an optional part of SCTP-PF.
The procedures defined in the document require only minimal
modifications to the current specification. The procedures are
sender-side only and do not impact the SCTP receiver.
