Abstract:
One of the major advantages of SCTP is that it supports 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 [RFC4960] specified
failover operation is followed there can be a significant delay in
the migration to the active destination addresses, thus severely
reducing the effectiveness of SCTP multi-homed operation.
The memo complements RFC4960 by the introduction of the Potentially
Failed state and associated new Quick Failover operation to apply
during network failure and specifies for SCTP senders to support this
more performance optimal failover procedure as an add-on to the
[RFC4960] failover operation. The memo in addition updates [RFC4960]
by clarifying a number of issues related to the path management
operation during periods of partial or complete network failures.
Finally the memo complements [RFC4960] by introduction of alternative
switchover operation modes for the data transfer path management
after a failover. These operation modes offer for more performance
optimal operation in some network environments. From the perspective
of this memo the implementation of the additional switchover
operation modes is considered optional.
The procedures defined require only minimal modifications to the
current specification. The procedures are sender-side only and do
not impact the SCTP receiver.
