Abstract: We analyze the unique features that arise from the bufferless property in OBS networks and design efficient schemes to route and configure connections considering these features. We study the feature called "streamline effect". It is that, due to the bufferless core nodes, if some connections share a link, there is no contention among them on the outgoing links. We present a loss estimation formula considering this effect. We also study the feature called "link residual capacity estimation". The method of computing residual bandwidth is not applicable to bufferless OBS networks. We propose a more accurate metric called residual admission capacity (RAC). The streamline effect is used to design effective offline route optimization algorithms for best-effort traffic. RAC is applied to develop solutions for routing end-to-end loss guaranteed connections and two problems in configuring end-to-end loss guaranteed connections, which are the loss budget partitioning problem and the loss threshold selection problem.
