A Study Of Bandwidth Sharing Mechanisms In Connection Oriented Networks

Our second book-ahead mechanism called Varying-Bandwidth Delayed Start (VBDS) is for data-type (file transfer) requests. By having applications specify file sizes in their reservation requests, a VBDS scheduler is able to assign a varying-bandwidth allocation for different time ranges instead of a single fixed-rate. Through simulations, we show that this approach improves system performance when compared to fixed-bandwidth schemes significantly.
