Tel-Aviv University - Computer Science Colloquium
Sunday, January 10, 14:15-15:15
The fast growth of the Internet and the introduction of new services introduce new challenges to the network management domain. New and more sophisticated tools are needed in order to efficiently use the new functionality, and to deliver a better quality of service to the end users. In this talk I will describe this new challenge, and present some of the work I have done to address it.
I will start by describing an SNMP management payload address translator. This tool enables the management of IP networks with colliding addresses from a single management station.
Then I will describe a work that addresses one of the substantial drawbacks of current network management systems. Many of these systems perform periodic polling that imposes a significant load on the network. We proposed methods for efficient monitoring of data network. In this work we presented a new model that allows quantifying the efficiency of polling, and developed new heuristics for efficient polling.
A third research project I will describe is a novel approach for application level management of IP networks using active networks. Active networks is a framework where network elements, (e.g., routers) are programmable. Using this technique, we designed and implemented a system that allows users to design their own management applications, and execute them on the network routers. In this ongoing research we also define a model that allows quantifying the complexity of performing management tasks using various frameworks of active network.
This talk is based on joint work with B. Denison, J. Jiao, P. Krishnan, S. Naqvi, Y. Shavitt, and B. Sugla.
