A new congestion control algorithm for active networks

This paper discusses and analyses different congestion control schemes for active networks and proposes a new one. The proposed scheme strikes a balance between the number of errors considered and the waiting time before taking action. The scheme implemented works on "Choke packet" concept, where the source is instructed to reduce the transmission rate. Reasonable reduction of transmission rate is maintained at the source as the intermediate nodes in active networks platform take actions instead of the usually acting destination nodes. The proposed scheme was simulated using OPNET and simulation results are reported. Results indicate that the source-quenching technique implemented in the intermediate nodes of the active network reduces congestion drastically and improves overall network performance

Optimizing The Search Of Access Control Lists For IP Packet Filtering Applications

A highly secured network with improved network performance in transmission control protocol internet protocol (TCP IP) is the main aim of this research. Diffrent parts of this theses are devoted to the study and analysis of security and performance of the IP packet filtering. We have studied networks of varying sizes in order to make research results applicable to computer networks in general. The network for checking IP packet filtering rules was designed and analyzed for security aspects using expert system and neural networks. Further the performances of such secure rules were improved using parallel system and active networks
