摘要：The widely used protocol based Simple Network
Management Protocol (SNMP) is today particularly limiting
due to the client-server centralized and static paradigm. The
approach is centralized as it relies on a limited set of
capabilities at network nodes while management processing
has to be performed at the network management station.
This requires transferring of large amounts of management
data between the manager and the managed nodes. In this
paradigm, the system does not auto respond to changes and
modifications in the network as hard coding is required to
make the necessary changes making the system inflexible.
Significant attempts have been made to develop solutions like
Remote Monitoring (RMON), Cisco Discovery Protocol
(CDP), Cisco Net flow Accounting and Monitoring by
Delegation (MbD), as an attempt to address the underlying
challenges faced. Distributed Object based approaches like
the Common Object Request Broker Architecture (CORBA)
and later by Remote Method Invocation (Java-RMI) have
been developed to address some of the underlying problems
of the SNMP protocol [17]. These solutions do not however
address dynamism, interoperability and responsiveness
required of current networks [13]. The MOMENT
(Monitoring and Measurement in the Next Generation
Technologies) makes bold contributions about the things that
ensure that network researchers will gain a better
understanding of current networks as well as of The
Network of the Future. But in our approach we use software
agents to collect and propagate statistics from different
Points of Presence to the Network Operations Center;
Update changes in the Network; process and present results.
With the agent paradigm in our system, the approach is able
to increase system’s responsiveness; to increase system
flexibility; to take advantage of distributed computing
resources, and to introduce interoperability, modularity and
dynamism into the monitoring system. In this paper, we
describe the system architecture and implementation of the
responsive model. In our MAS model, the system is seen to
reduce the time taken to initiate and update client
parameters in the system; releases time for the
administrators that can be used in other productive
activities; eliminates mistakes that could be done by the
administrators as the system has controls that ensure the
agents only use the exact information as provided from the
database; the system optimizes responsiveness by ensuring
changes done on the database are automatically updated to
the agents database which makes the relevant changes on the
graphs and monitored parameters of the clients. This
ensures the system is responsive to changes, increases
flexibility and dynamism.
