Strategies for Dynamic Network Management
Åke Arvidsson · 1993
We study management of transport networks based on virtual paths, i.e. rearrangable end-to-end transport network \\highways". Among its main advantages are found cost savings, network operation simpli cation and enhanced network management capabilities. Virtual paths networks are readily implemented in any network using the synchronous digital hierarchy and/or the asynchronous transfer mode. Algorithms for virtual path designs are reviewed and found to have a few shortcomings. A new algorithm is therefore proposed and it is found to compare favourably with the algorithm providing the most similar features. Applying the proposed algorithm to a large number of networks, we discuss operational considerations associated with recon gurable networks and investigate simple tra c estimation procedures and their performance in this context. Finally, the choice of recon guration parameters such as updating frequency, and the impact of network design time are examined. 1 Recon gurable Virtual Path Networks for ATM 1.1 Description
