Spatial Reuse Protocol BOF (srp)

Wednesday, November 10 at 1530-1730
===================================

CHAIR: David Tsiang <tsiang@cisco.com>

DESCRIPTION:

SRP (Spatial Reuse Protocol) is a MAC layer protocol for local, metro, 
and wide area rings developed at Cisco Systems. OC12c SRP interfaces 
have been tested and deployed at several sites within the Internet.

The main goals of SRP are:

 - Efficient use of bandwidth using:
   spatial reuse of bandwidth
   local reuse of bandwidth
   minimal protocol overhead

 - Support for priority traffic

 - Scalability across a large number of nodes or stations attached to
   a ring

 - "Plug and play" design without a software based station management
   transfer (SMT) protocol or ring master negotiation as seen in other
   ring based MAC protocols

 - Fairness among nodes using the ring

 - Support for ring based redundancy (error detection, ring wrap,
   etc.) similar to that found in SONET BLSR specifications.

 - Independence of physical layer (layer 1) media type.

An internet draft has been published and can be found at

   http://search.ietf.org/internet-drafts/draft-tsiang-srp-00.txt 

We would like to propose the establishment of a working group to 
evaluate, improve, and standardize protocols that relate to IP over SRP.

AGENDA:

Brief Overview of SRP 
  (15 min)

List of current and planned deployments 
List of users, vendors, researchers interested in a WG.
   (5 min)

Peter Lothberg with a user perspective. 
  (10 min)

Thomas Narten will say a few words about what has gone on so far in the 
IESG
 - i.e. what the current thinking is on the split between IEEE and IETF.
   (5 min) 

Discuss what should be standardized in the IEEE 
  (25 min)
  Examples:
    - L1 SRP over SONET, SRP over xxxx
    - L2 MAC including fairness algorithm

Discuss what should be worked on or standardized in the IETF 
  (25 min)
  Examples:
    - IP over SRP
    - MPLS over SRP
    - RRR over SRP
    - IPS (Intelligent Protection Switching) for SRP

Discuss what the relationship should be between the IEEE and the IETF 
  (10 min)

Discuss the timing of work (can stuff be done in parallel or are 
there serial dependencies) and potential WG output (list of drafts, 
informational or proposed standard) 
  (20 min)
