This paper presents an approach to speed up and enhance matching of virtual network requests to available resources in virtual network provisioning frameworks. The method consists of introducing a weight or score expressing the importance of the resources, their attributes and the values taken by these attributes. The scores are obtained through statistical analysis of the requests for virtual network...
Most of the link rate adaptation algorithms reduce transmission rate on a failed transmission assuming the cause of the loss to be due to radio channel impairment. However, if this failure is due to collision, then lowering the transmission rate in response is unnecessary. This paper proposes a solution to address this problem by augmenting the rate adaptation algorithm with a loss classification...
Packet classification is an important topic for high speed routers nowadays. There are many packet classification algorithms based on decision tree like Hicuts, Hyper cuts and Hyper split. Because Hicuts and Hyper cuts divides the rule sets by cutting the address space into equal-sized subspaces, their cutting efficiency is not good. Although Hyper split proposed a good end-point-based cutting scheme,...
