Abstract
Currently, with both optical and packet heterogeneous paths existing in space optical-electrical hybrid switching system, the method of independently calculating the optical/packet switching path cannot comprehensively consider the availability of the system’s path resources, which result in the possibility of selecting irrational switching path and making the path load of the switching system unbalanced, even may cause high path blocking probability. In this paper, the homogeneous path influence factor and the heterogeneous path influence factor are defined to quantitatively measure path weights, and based on the optical/packet integrated signaling, a load-balanced and heterogeneous switch path algorithm (LHSP) is proposed to calculate the internal heterogeneous switching path. Moreover, the load balancing degree and the path blocking probability are simulated based on Switching Structure Simulation Model in OPNET. Extensive simulation results show that the LHSP algorithm can reduce average load balancing degree by about 32% and average path blocking probability by about 51% with previous algorithm.
