[rbridge] Need your comments to the update of "trill-directory-assisted-edge"

[Linda Dunbar]

After this draft was discussed at the 81st IETF, many people gave me comments and suggestions. Several people suggested to break the draft to two separate ones, with one draft on Directory Assisted TRILL Edge and the other draft to describe how/why to use directory assistance for non-Rbridge to encapsulate TRILL header. 

I made significant changes to the draft. Major changes include:
-	Break the draft to two separate ones: Directory assisted Edge and Directory Assisted non-Bridge Performing Encapsulation. 
-	Include an example of mapping table which can be “pushed down” or “pulled from” to RBridge edge.  


The abstracts of the drafts are outlined below. Hope to get your comments and suggestions prior to the Taipei meeting. 

Thanks, Linda Dunbar

Filename:	 draft-dunbar-trill-directory-assisted-edge
Revision:	 03
Title:		 Directory Assisted RBridge Edge
Creation date:	 2011-10-26
WG ID:		 Individual Submission
Number of pages: 13

Abstract:
   RBridge edge nodes currently learn the mapping between MAC addresses
   and their corresponding RBridge edge nodes by observing the data
   packets traversed through. When ingress RBridge receives a data
   packet with its destination address (MAC&VLAN) unknown, the data
   packet is flooded across RBridge domain. When there are more than
   one RBridge ports connected to one bridged LAN, only one of them can
   be designated as AF port for forwarding/receiving traffic for each
   LAN, the rest have to be blocked for that LAN.

   This draft describes why and how directory assisted RBridge edge can
   improve TRILL network scalability in data center environment.

Title:		 Directory Assisted TRILL Encapsulation
Creation date:	 2011-10-26
WG ID:		 Individual Submission
Number of pages: 9

Abstract:
   This draft describes how data center network can benefit from non-
   RBridge nodes performing TRILL encapsulation and how directory
   service can assist a non-RBridge node to encapsulate TRILL header.
