Precomputation Schemes for QoS Routing

Free registration required

Executive Summary

Precomputation-based methods have recently been proposed as an instrument to facilitate scalability, improve response time and reduce computation load on network elements. The key idea is to effectively reduce the time needed to handle an event by performing a certain amount of computations in advance, i.e., prior to the event's arrival. Such computations are performed as background processes, thus enabling to promptly provide a solution upon a request, through a simple, fast procedure.
