An Optimal Algorithm for Scheduling Reservations in a Bandwidth Market
An algorithm is presented which provides an optimal
solution to the problem of scheduling non-relocatable time
intervals of bandwidth in differentiated services networks.
Simulations found an asymmetry between valuing an interval’s
length and bandwidth requirement. Longer intervals requiring
less resource are favored over shorter intervals requiring more
resource. The optimal algorithm is shown to respond appropriately
to price as a mechanism of control whereas the offline
greedy and the online FCFS algorithms do not. The solution
uses integer programming, and it is shown that, except in the
general case, the problem can be solved in polynomial time.
