PROJECT AUTHORIZATION REQUEST (PAR)

1. Date of Request: 14 March 1996

2. Assigned Project#: 802.1Q

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

4. Description of Proposed Document: New Standard   Full Use

5. Project Title:
            Standard for Virtual Bridged Local Area Networks

6. Scope of Propose Standard:

   To develop an architecture and bridge (-1-) protocols for the
   logical partitioning of a Bridged Local Area Network (-1-, -2-, -3-)
   that provides separate instances of the MAC service (-4-) to
   administratively defined groups of users, independent of physical
   location.  The architecture and protocols will be compatible and
   interoperable with existing Bridged Local Area Network equipment and
   will support a range of implementations.

   To define basic management of the groups.

   This project will not include explicit consideration or development
   of multiple active paths within a VLAN, enhanced quality of service,
   or security facilities.  However it will not preclude their eventual
   development except as restricted by (-1-).

   -1- ISO/IEC 10038, ANSI/IEEE Std. 802.1D.
   -2- ANSI/IEEE Std. 802.1D Annex C.
   -3- P802.1G
   -4- ISO/IEC 15802-1, ISO/IEC 10039.

   Note: See Attachment:  Interpretations

7. Purpose of Proposed Standard:

   The set of technologies known as Virtual LANs provide the equivalent
   of separate LANs over a single bridged LAN.  Despite user demand
   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.

Attachment:  Interpretations

   In Scope -

       "Users" includes the notion of different protocols in the same
       endstation using different VLANs.

       "Administratively defined" includes a wide range of user
       administrative choices from equipment purchase, through policy
       setting, static configuration, in-band and out of band management,
       and automatic configuration guided by policy choice.

       Logical partitioning of a Bridged Local Area Network by VLAN
       mechanisms may be an appropriate element in a comprehensive system
       of user security.  However, an explicit orientation of VLAN to
       security may conflict with primary goals of ease of use, and would
       be a significant addition to the scope of this project.  Further
       work in this area may take place under a separate PAR at an
       appropriate time.

       Consideration and accommodation of bridging techniques based on
       802.1D (e.g., 802.5r Annex K) is within the scope of this PAR.

       "Compatible and interoperable" includes the idea that new bridges
       implementing 802.1Q can be intermixed with existing 802.1D bridges
       in configurations with require the latter to forward but not
       interpret VLAN information.

       "Multiple active paths within a VLAN" means multiple active paths
       between the same two users.
