Planned Future Work n 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. n Future work requires parallelize the rules on-the- fly and allocated job to the respective routers using active networks. n To induce routing decisions using active networks. One scenario is to make Link-state protocols stabilize faster. n 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. n Future work requires parallelize the rules on-the- fly and allocated job to the respective routers using active networks. n To induce routing decisions using active networks.

Software Engineering research project n Project: Investigating Design Quality Characteristics for Refactoring and Refactoring To Patterns Using Software Metrics n Objective: to confirm or invalidate the claims that cost and time put into refactoring are worthwhile. n 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. n Using software metrics, we will quantitatively investigate whether those approaches really improve software quality or not n Project: Investigating Design Quality Characteristics for Refactoring and Refactoring To Patterns Using Software Metrics n Objective: to confirm or invalidate the claims that cost and time put into refactoring are worthwhile. n In this research we will investigate: An approach to detect the need to refactor early in the software process.
