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 memo complements [RFC4960] by the introduction of the
Potentially Failed path state and the associated new failover
operation called SCTP-PF to apply during a network failure. In
addition, the memo complements [RFC4960] by introducing of
alternative switchover operation modes for the data transfer path
management after the recovery of a failed primary path. These modes
offers for more performance optimal operation in some network
environments. The implementation of the additional switchover
operation modes is optional.
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.
