Abstract

We consider the problem of selecting an appropriate LSP (label switched path) for a new connection request from several possible LSPs which can satisfy the QoS of the new connection. We propose an active measurement approach where a probing stream is sent along each LSP. Based on the end-to-end delays of the packets of the probing stream, we estimate the mean delays and the throughput the new connection can get. Our approach allows the effect of the new connection also to be included in estimating the mean delay and the throughput. The new connection may use TCP or UDP.
