    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
