a survivable embedding based on lightpath reliability and spectrum integration factor-aware (SE-LRSIF) algorithm is proposed for virtual optical networks in space-division multiplexing elastic optical networks. During virtual node embedding
a weight evaluation criterion is designed to comprehensively consider the attributes of physical nodes. During virtual link embedding
a working lightpath selection strategy that jointly considers spectrum resources and reliability is designed
and a working lightpath spectrum partition allocation method based on spectrum integration factor-aware is designed to make network spectrum resources more integrated. Moreover
a protection lightpath selection strategy is designed to increase the protection bandwidth sharing. The simulation results show that the proposed SE-LRSIF algorithm can significantly improve the acceptance ratio of virtual optical network requests and reduce the bandwidth blocking probability.
