Access control using expert system, artificial neural networks and parallel rules have been tested on both active and non-active platforms.

Real-time platform• Language used: Java.

• Clustering of PCs using PVM.

• Heterogeneous platforms used.

Processing on the fly was tested by linking the C code of PVM to handle MATLAB applications.

A 16-node Active Network system with both ergodic and non-ergodic capabilities have been tested on NS Simulator.

In general, the access lists are fixed for a network and so its easy to parallelize them and then apply it using active networks approach.

Future work requires parallelize the rules on-the-fly and allocated job to the respective routers using active networks.

To induce routing decisions using active networks. One scenario is to make Link-state protocols stabilize faster.

Project: Investigating Design Quality Characteristics for Refactoring and Refactoring To Patterns Using Software Metrics

Objective: to confirm or invalidate the claims that cost and time put into refactoring are worthwhile.

In this research we will investigate: • An approach to detect the need to refactor early in the

software process.

• Two refactoring approaches: refactoring to produce design patterns, and refactoring that produces code without design patterns.

Using software metrics, we will quantitatively investigate whether those approaches really improve software quality or not
