1. FCoE over TRILL draft-mme-trill-fcoe-00 http://tools.ietf.org/html/draft-mme-trill-fcoe-00 Informational http://tools.ietf.org/html/draft-mme-trill-fcoe-00 David MelmanMarvell Tal MizrahiMarvell Donald Eastlake, 3rdHuawei IETF Meeting 81, July 2011

2. 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. 3 Background (2) The TRILL topology is very similar. RBridges play similar roles as FCFs.

4. 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. 5 FCRB – FCF over RBridge

6. 6 Data Center Topology with FCRB

7. 7 Next Steps July 2011 – draft 00. Receive feedbacks from WG.

8. Thanks

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