Internet packet routing: Application of a K-quickest path algorithm
Clímaco, João C. N.; Pascoal, Marta M. B.; Craveirinha, José M. F.; Captivo, M. Eugénia V.This paper describes a study on the application of an algorithm to rank the K-quickest paths to the routing of data packets in Internet networks. For this purpose an experimental framework was developed by considering two types of random generated networks. To simulate values of the IP packet sizes, a truncated Pareto distribution was defined, having in mind to reflect a key feature of Internet traffic, namely ...
An algorithm for ranking quickest simple paths
Pascoal, Marta M. B.; Captivo, M. Eugénia V.; Clímaco, João C. N.In this paper, an algorithm for ranking loopless paths in undirected networks, according to the transmission time, is presented. It is shown that the worst-case computational time complexity of the algorithm presented is , which is also the best-known complexity to solve this problem. The worst-case memory complexity is , which improves the existing algorithms. Finally, comparative computational results, with o...
