TELETRAFFIC PERFORMANCE OF MULTI-WAVELENGTH OPTICAL CROSS-CONNECTED NETWORKS USING WAVELENGTH TRANSLATION

The teletraffic performance of regular twoconnected multi-hop datagram optical networks in uniform traffic under hot-potato routing and wavelength translation is presented. Manhattan Street (MS) Network and ShuffleNet (SN) are compared in terms of average propagation delay and throughput. We analyze a wavelength translation (WT) node architecture. Such an architecture decreases packet deflection by providing the possibility of an optimized wavelength translation routing. Packets are wavelength translated in the case of local conflict at a node to avoid deflection; otherwise they transparently traverse the node.
