IEEE Standards
        *DRAFT* PROJECT AUTHORIZATION REQUEST (PAR) (rev 1.2)

1. Date of Request: 11 March 1998

2. Assigned Project#: 802.1?

3. Does this PAR revise a previously approved PAR: NO

4. Description of Proposed Document: New Standard   Full Use

5. Project Title: Standard for Local and Metropolitan Area Networks -
                  Supplement to Virtual Bridged Local Area Networks:
                  Multiple Spanning Trees

6. Scope of Propose Standard:

   To develop an architecture and protocols for the use of multiple
   instances of the Spanning Tree Protocol (-1-) within a network
   employing VLANs (-2-).  The architecture and protocols will be
   compatible and interoperable with existing Virtual Bridged Local
   Area Network equipment and will support a range of implementations.

   To define basic management of the Spaning Trees.

   -1- ISO/IEC 15802-3, ANSI/IEEE Std. 802.1D.
   -2- IEE Std. 802.1Q (going to sponsor ballot)

7. Purpose of Proposed Standard:

   ANSI/IEEE Std. 802.1Q Virtual LANs provide the equivalent
   of separate LANs over a single bridged LAN, using a single instance
   of the Spanning Tree Protocol.  Despite multiple independent
   implementations employing multiple instances of the Spanning Tree
   Protocol, there is currently no interoperability between different
   vendors, nor a coherent management framework for different
   techniques.  This Standard will provide an architecture, protocols,
   and mappings for bridges to provide that interoperability and
   consistent management.

8. SPONSOR: LMSC

9. Name of group that will write the standard:
       IEEE Project 802.1 Working Group

10. Target Completion Date: May 1999

11. Proposed Coordination:                Method of Coordination:
