Fibre Channel over Pseudo-Wire • draft-ietf-pwe3-fc-encap-01.txt • FC traffic encapsulation in packets for MPLS • Protocol will be joint IETF/FC-BB-4 work. • Analogous to FCIP development (with FC-BB-3) • Liaison issue resolved: Congestion control • Specification of TCP-class congestion control for the FC PW will done in IETF as opposed to in T11. • IETF pwe3 WG is working on congestion control for pseudo-wires in general 06-740v1
FC Addresses in ELS payloads • FC-IFR uses address translation • S_ID and D_ID change across fabrics • iFCP also uses address translation • Separate FC domain at each gateways • Some ELSs have embedded addresses • FC-IFR is specifying the necessary translation • This FC-IFR work is applicable to iFCP • Remove ELS address translation details from iFCP RFC • Revised iFCP RFC would reference FC-IFR instead • Revision timeline for iFCP RFC is TBD 06-740v1
