Modelling IEEE Spanning Tree protocols using an UML Class Diagram

Spanning Tree and other relative protocols, produced by the IEEE 802.1 working groups, are defined using plenty of cross references. To really understand the dependencies between those protocols, I wrote an UML class diagram taking into account those relationships, in the last revision of these documents.

Here are the classes involved in the diagram:

  • 802.1w-2001: Rapid Reconfiguration of STP (supplement to 802.1D-1998)
  • 802.1s-2002: Multiple Spanning Trees (supplement and amendment to 802.1D-1998)
  • 802.1Q-2003: Virtual Bridged LANs
  • 802.1D-2004: MAC Bridges (revision of 802.1D-1998, incorporating 802.1w - Note that 802.1D-1998 is an amendment of 802.1D-1993)
  • MSTP: Multiple Spanning Tree Protocol
  • GARP: Generic Attribute Registration Protocol
  • GMRP: Generic Multicast Registration Protocol (used by GARP)
  • GVRP: GARP VLAN Registration Protocol
 

Some manufacturers, like Cisco, tried to introduce proprietary protocols solving the same problems than standard IEEE 802.1 protocols: PVST, PVST+, Rapid-PVST. You will not find them in this class diagram.
