Description of Working Group:
The base General Switch Management Protocol (GSMPv3) protocol has been submitted to the IESG with the request that it become a proposed standard. Currently the GSMP protocol provides switch configuration control and reporting, port management, connection control, QoS and traffic engineering control and the reporting of statistics and asynchronous events for MPLS label switch devices, all either from or to a third party controller.

The working group is responsible for completing the standardization of the GSMP protocol by responding to protocol issues that arise during implementation of the current specifications.

Additionally, the working group is responsible for augmenting the protocol as follows:

- Support for Optical and Other Extensions and CCAMP Features

The architecture of some optical, TDM, spatial and other switch types makes the ability to remotely control the connection state of a switch important. GSMP has been designed especially for such remote control operations. GSMP is, however, currently lacking in the specific semantics necessary for switches with some new technologies, especially in the optical space. The WG will collect requirements and define solutions to support optical and other new switching technologies, compatibly with the common control and measurement protocols WG (CCAMP) work. This work will be done in cooperation with the other Sub IP Working groups involved in this area.

The extensions will include definition of new instances of "labels" (for instance lambda identifiers) as needed, to support the usage in the new technologies. They will also include definitions of port types, of service definitions and of traffic parameters.

- Switch Partitioning

The current version of GSMP is designed to work with a static switch partition. Recently, some regulatory environments (on multiple continents) have mandated multi-provider access to the same physical infrastructure. The working group will develop extensions to GSMP to support dynamic switch portioning. This work would be to adapt GSMP to work with multiple partitions in which resource allocation is dynamic and variable between the switch partitions. This work would allow network operators to dynamically open their forwarders (optical, TDM, and other switch types) to multiple administrative domains of control. The working group will also see what is achieved by using available management tools, e.g. MIBs to monitor and control dynamic switch portioning.

- Relationship to Forwarding and Control Element Separation

The WG will conduct a brief (one-meeting) analysis of the potential use of GSMP in mechanisms that allow third party network processors in switch architectures. The output will be an agreement of the likely scope for a distinct WG that might be using GSMP for this purpose.

Goals and Milestones:
Done  Define an IP encapsulation for GSMP messages
Done  Extend GSMP message types to allow support of non-ATM Label Switch devices
Done  Refine the support for QoS models in GSMP
Done  Define an approved GSMP MIB
Done  Define approved mechanisms for security and authentication in GSMP
Done  Produce a version of the GSMP which has the consensus required for entry onto the standards track.
Done  Analyze role of GSMP for control element separation and make recommendation as to a separate WG for extending GSMP for this
Done  Document requirements for control of switches supporting optical, TDM and other CCAMP features
Done  Document requirements for switch partitioning and determine whetherto recharter to extend GSMP capabilities to meet these
DEC 02  Submit GSMPv3 extensions to include control of switches supporting optical, TDM and other CCAMP features and any updates of the base spec for Proposed Standard
JUN 03  Submit GSMPv3, its extensions and MIBs for Draft Standard
JUN 03  Conclude Working Group
