Abstract

The Data Exchange Executive is a network studies application with the ability to take automated action using an appropriate network management protocol based on the network management domain or domains to be controlled. The fundamental concepts involved are described in [*]. The Data Exchange Executive depends on the Data Exchange and associated Protocol Domain Managers as shown in Figure 1. The Data Exchange is the means for gathering and disseminating data to the Protocol Domain Managers. The Protocol Domain Managers perform real-time management of one or more homogeneous networks or apparently homogeneous networks through the use of agents.

Data Exchange Executive

      The Data Exchange Executive is a network studies application
with the ability to take automated action using an appropriate
network management protocol based on the network management domain or
domains to be controlled.  The fundamental concepts involved are
described in [*].  The Data Exchange Executive depends on the Data
Exchange and associated Protocol Domain Managers as shown in Figure
1.  The Data Exchange is the means for gathering and disseminating
data to the Protocol Domain Managers.  The Protocol Domain Managers
perform real-time management of one or more homogeneous networks or
apparently homogeneous networks through the use of agents.

      The Data Exchange Executive provides the capability to define
"Domain management Policies (DMPS)" and to dynamically update these.
DMPS can be defined that provide support for all network management
disciplines, including in part:

o   Fault
o   Performance
o   Configuration
o   Accounting
o   Inventory
o   Asset Management
o   Installation and Migration
o   Distribution
o   Hardware Product Unique Support
o   Microcode Product Unique Support
o   Software Product Unique Support

      The Data Exchange Executive gives "policy" guidance to the
entire communications and application network.  The relationship
parallels the human management structure found in organization, i.e.,
the executive makes policy decisions considering the entire set of
corporate interests, while the manager makes operational decisions
within the policies but tailored to immediate conditions.

The interface between the Data Exchange Executive and the domain
manager provides:

o   Definition of a "policy"
o   States that a policy can be in
o   Syntax and semantics for expressing policies and information
    about policies

      If a manager manages and an executive sets policies, then what
is a "policy"?  A policy is a set of choices that a manager can
choose to take under appropriate conditions.  Also, when a policy is
set, the executive also specifies what kind of reporting is required
about compliance to that policy.  One executive might "micro-manage"
and require frequent compliance reports.  Another executive might be
"laissez-faire" and want infrequent reports.

      Policies are defined using the ISO/CCITT GDMO/ASN.1 language.
However, note that SNMP SMI and other protocol-domain-specific
languages that are subsets of GDMO may also be used.

      The following describes four example policy objects using the
ASN.1 language subset used with SNMP objects.  Not that these
examples are also valid for GDMO since it is a proper superset of the
SNMP subset language.

The four objects described here provide for the following:

o   Definition of a Class of Service (COS)

          A Class of Service is defined by an enterprise or
    establishment.  For example, with telephone service, some
    customers provide a CO...
