FCoE over TRILL draft-mme-trill-fcoe-00 Informational David Melman Marvell Tal Mizrahi Marvell Donald Eastlake, 3rd Huawei IETF Meeting 81, July 2011
2
Background FCoE – Fibre Channel over Ethernet (FCoE).
FCF – FCoE Forwarder. ENode – FCoE end node. FCF functionality is a bit similar to RBridge in terms of: Forwards Ethernet frames based on higher layer address. Modifies MAC addresses to reflect next hop.
3
Background (2) The TRILL topology is very similar.
RBridges play similar roles as FCFs.
4
FCoE with TRILL (1) What happens when we have FCoE and TRILL in the same network? Separate cloud approach: FCoE traffic between hosts must be forwarded through an FCF. With separate clouds: goes through more hops.
5
FCRB – FCF over RBridge
6
Data Center Topology with FCRB
7
Next Steps July 2011 – draft 00. Receive feedbacks from WG.

Thanks

Data Center Topology with FCRB (2)
EoR are RBridge – not FCRB. Traffic between FCRBs is forwarded over TRILL cloud.
