On the amount of bandwidth allocated to virtual paths in ATM networks
Raif O. Onvural, Y.C. Liu · 2003
The virtual path (VP) concept in asynchronous transfer mode (ATM) networks is introduced to minimize the network management and control costs. A VP provides a logical connection between two end nodes. VPs have their own allocated bandwidth and each VP is mapped on to a set of physical links connecting the two nodes. Virtual channels (VCs), on the other hand, provide a logical connection between two users. Accordingly, a number of VCs are multiplexed on a VP and a number of VPs are multiplexed on physical links. The effect of multiplexing traffic on the amount of bandwidth allocated to VPs is investigated.>
