Innovative Architectures For Ops/obs Advanced Photonic Networks

In this work we present new architectures having new sets of link connections for mesh network (Manhattan St. type) and a for ring topology, with both using unidirectional and (one case) bi-directional links. For the comparative analysis we adopt two types of optical node configurations for both ring and mesh topologies, using 2x2 and 3x3 input/output connections. Other node functionalities such as add/drop do not impact directly on optical layer performance considered here. The traffic was analyzed in these new network topologies in terms of average number of hops and throughput under uniform traffic distribution. Our results are based on analytic studies and computer simulations. ©2009IEEE.673677Yoo, S.J., Optical Packet and Burst Switching Technologies for the Future Photonic Internet (2006) J.
