Paper Abstract

The ILP based on source formulation is newly proposed in recent literatures. This paper firstly applies the ILP based on source formulation into the current popular Waveband switching (WBS) network. Our research shows that the ILP based on source formulation can effectively improve the network performance. Two optimized WBS network scenarios are discussed in this paper, including the networks constructed with multi-granular OXCs (MG-OXC) and the networks which is not limited to MG-OXCs but constrained by the condition that all wavebands only contain lightpaths to the same destination. Numeric results show that source-formulation ILP can require less computational effort compared to flow-formulation ILP.
