In the area of network monitoring, I work on the Chatter system. The Chatter system, a lightweight, real time, distributed monitoring system aimed at converged networks. The Chatter system monitors critical resources for possibly very large networks but requires no central server. The Chatter system can be configured to maintain multiple process control charts and to trigger alarms when various conditions are met. The Chatter system includes a powerful visualization tool which is designed to show various aspect of the network at a glance. In the area of reliability, I work on Orbit. Orbit is a very elementary overlay network technology that can be used to improve the reliability of IP telephony on any network. The idea is to circumvent local network problems by using ricochet on cooperating network elements that are called Orbit relays. The function of Orbit relays could be played by Avaya phones or gateways, for example. |
