Abstract

This paper proposes an algorithm namely DVPM (Dynamic Virtual Path Management) that aim to adjusting the virtual path (VP) pool in ATM networks. The objective of the adjustment is to match the VP pool with the forecast traffic behavior to maximize revenue and minimize network transient which occur when there is a failure of a network element such as a link. A comparison is made between DVPM and FVPM (Fixed Virtual Path Management), comparing the performance achieved by each. The achieved revenue of DVPM and FVPM is compared to the optimal revenue. The simulation example illustrates how DVPM adapted the VP pool to handle the incoming traffic to achieve maximum revenue in the situation of a link failure. The result show that the revenue from DVPM is better than the revenue from FVPM when the network failure. It is about 20.84% different and close to the optimal revenues within 2.42% different.
