Traffic engineering has been the prime concern for Internet service providers (ISP's), with the main focus being minimization of over-utilization of network capacity even though additional capacity is available which is under-utilized. Furthermore, requirements of timely delivery of digitized audiovisual information raises a new challenge of finding a path meeting these requirements. This paper addresses the issue of (a) distributing load to achieve global efficiency in resource utilization, (b) Finding a path satisfying the real time requirements of delay and bandwidth requested by the applications. In this paper we do a critical study of the link utilization that varies over time and determine the time interval during which the link occupancy remains constant across days. This information helps in predetermining link utilization that is useful in balancing load in the network. Finally, we run simulations that use a dynamic time interval for profiling traffic and show improvement in terms number of calls admitted/blocked.
