Abstract :
This paper proposes k-regular and k-connected (k&k) structure against multi-faults in ultra-high capacity optical networks. Theoretical results show that pre-configured k&k structure can reach the lower bound on logical redundancy. The switching time of k&k protection structure is as quickly as ring-based protection in SDH network. It is the optimal protection structure in ultra-high capacity optical networks against multi-faults. We develop the linear programming model for k&k structure and propose a construction method for k&k structure design. Simulations are conducted for spare spectrum resources efficiency of the pre-configured k&k structure under multi-faults on representative COST239 and NSFnet topologies. Numerical results show that the spare spectrum resources efficiency of k&k structure can reach the lower bound on logical redundancy in static networks. And it can largely improve spare spectrum resources efficiency compared with p-cycles based protection structure without reducing protection efficiency under dynamic traffics.
