Abstract
A network should deploy QoS-aware path selection algorithms for efficient routing. To this end, measurements of the various characteristics of the network can provide insight into the state and performance of the network. In this paper, we present a new QoS-aware path selection algorithm for flows requiring bandwidth guarantees based on an estimation algorithm for the available bandwidth on the links of the network. The estimation algorithm for the available bandwidth predicts the available bandwidth and also tells the duration for which the estimate is valid with a high degree of confidence. Thus, the path selection algorithm is adaptive and not very computationally intensive.
