- ABSTRACT
-
- In today's corporate and educational environments,
- there is an ever-growing need to provide network
- management for large heterogeneous networks. The Simple
- Network Management Protocol (SNMP) has been proposed as
- a standard by the Internet community to perform this
- function. Although SNMP has gained wide acceptance, we
- have identified deficiencies in two areas: scalability
- and manager-to-manager communication. The SNMP
- philosophy of a manager polling an agent to obtain
- information does not scale well to large networks with
- hundreds of hosts. In addition, there is no mechanism
- for one manager to communicate with or make collected
- information available to another manager. We introduce
- the concept of the AGGREGATE AGENT to solve these
- problems. The aggregate agent provides a method of
- subdividing a large task so it can be handled by
- multiple managers, allows the imposition of a hierarchy
- for the flow of network information, and supports a
- mechanism for a manager to make its information
- available to other managers. The talk focuses on
- illustrating the aggregate-agent concept by describing
- an implementation of a network-management application
- that employs aggregate agents. This application
- monitors the average packet load for an arbitrary group
- of subnets. The collection method used in the
- application is validated by graphical comparison and
- spectral analysis relative to data collected by a
- protocol analyser. An experimental deployment on a
- group of eight subnetworks comprising over 180 hosts is
- described and the data collected is presented and
- analyzed.
