Abstract

The Stream Control Transmission Protocol (SCTP) supports multihoming.However, when the failover operation specified in RFC 4960 isfollowed, there can be significant delay and performance degradationin the data transfer path failover. This document specifies a quickfailover algorithm and introduces the SCTP Potentially Failed(SCTP-PF) destination state in SCTP Path Management.

This document also specifies a dormant state operation of SCTP thatis required to be followed by an SCTP-PF implementation, but it mayequally well be applied by a standard SCTP implementation, asdescribed in RFC 4960.

Additionally, this document introduces an alternative switchbackoperation mode called "Primary Path Switchover" that will bebeneficial in certain situations. This mode of operation applies toboth a standard SCTP implementation and an SCTP-PF implementation.

The procedures defined in the document require only minimalmodifications to the specification in RFC 4960. The procedures aresender-side only and do not impact the SCTP receiver.
