Description of Working Group:
The Distributed Management Working Group is chartered to define an initial set of managed objects for specific distributed network management applications which can be consistently developed and deployed. A distributed network manager is an applicaton that acts in a manager role to perform management functions and in an agent role so that it can be remotely controlled and observed.

Distributed network management is widely recognized as a requirement for dealing with today's growing internets. A manager application is a good candidate for distribution if it requires minimal user interaction, it would potentially consume a significant amount of network resources due to frequent polling or large data retrieval, or it requires close association with the device(s) being managed.

The working group will limit its work to distributed network management applications where the main communication mechanism for monitoring and control is SNMP. Future work (and other working groups) may be chartered to investigate other distribution techniques such as CORBA or HTTP. The objects defined by the working group will be consistent with the SNMP architecture defined in RFC 2571. The working group will especially keep security considerations in mind when defining the interface to distributed management.

The working group will complete these tasks:

Define a Scheduling MIB

Define a Script MIB

Define a Remote Operations MIB

Define an Expression and Event MIB to support Threshold Monitoring

Define a Notification Log MIB

Define an Alarm MIB

The working group will consider existing definitions, including:

o the RMON working group's work in this area

o the Application MIB (RFC 2564), SysAppl MIB (RFC 2287) and related standards.

The work on the Alarm MIB will take into consideration existing standards and practices, such as ITU-T X.733. Whether any mappings to these other standards appear in the Alarm MIB or in separate documents will be decided by the WG. The WG will actively seek participation from ITU participants to make ensure that the ITU work is correctly understood.

It is recognized that the scope of this working group is narrow relative to the potential in the area of distributed network management. This is intentional in order to increase the likelihood of producing useful, quality specifications in a timely manner. However, we will keep in mind and account for potential related or future work when developing the framework including:

o Event and alarm logging and distribution

o Historical data collection/summarization

o Topology discovery
