  1. FCoE over TRILLdraft-mme-trill-fcoe-00http://tools.ietf.org/html/draft-mme-trill-fcoe-00Informational 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.

  8. Thanks

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