Static Multipoint to Multipoint Buses Placement in Transparent Optical Networks

We propose a node architecture supporting the packet-oriented multipoint to multipoint (MP2MP) transparent optical passive buses. The main goal of the bus concept is to minimize costs by maximizing resources utilization in transparent optical mesh networks. We first formulate the problem of MP2MP passive optical bus placement (OBP) as an ILP problem with linear constraints in case of static traffic demands. We propose next a heuristic named Maximizing Resources Utilization (MRU). We use further the MRU dimensioning with two traffic models. We compare the concept of MP2MP bus to the multipoint-to-point (MP2P) passive optical bus and an active MP2MP bus (MP2MP with online optical packet erasing) called also Optical Packet Switching (OPS). We finally derive conclusions from the numerical results on the performance of both the passive and active MP2MP optical and the MP2P bus as well as on the MP2MP passive bus and the OPS active one.
