Abstract
As computer networks increase in size and expand geographically, the necessity to
monitor them becomes increasingly important. Thus, new techniques and mechanisms
for distributed network monitoring are needed to accommodate the above situation.
The intent of this thesis is to develop a platform to support real time passive distributed
network monitoring applications. The platform will use the open architecture concept for
other application developers to add functionalities or extend existing functionalities.
The platform also proposes three new concepts in real time passive network monitoring.
The first is the 3-tier architecture to ensure a complete coverage of the distributed
network as well as balancing the load among all distributed network monitoring
elements. The second concept is the innovative buffering technique that is used to handle
the high speed network traffic with minimal packet loss as well as minimizing the
processing and network overhead. Finally, the third concept is the distributed passive
data gathering with a central coordination server. Each element has intelligence built-in
to pre-process the passive gathered data and reduce the bandwidth consumption between
the central coordination server and the distributed monitoring elements.
Finally, we implement a distributed real time network monitoring application
GEnterprise) utilizing the RTDNM platform. We deploy the implemented application
into an enterprise network (Nav6). However, this implementation proves the RTDNM
platform ability to allow other applications to extend the platform cores through its
available APls and extension points. The deployment of the implemented application
further proves the ability of the RTDNM platform based application to be integrated into
heterogeneous network environments.
