Abstract
In this paper, we propose the design of a survivable energy-efficient and crosstalk-aware routing, spectrum, and core allocation (RSCA) scheme for online multiclass traffic in both spectral and temporal domains in SDM-EON. Multipath based protection scheme is applied to ensure survivability against single link failure. Advanced reservation (AR) connections being a part of multiclass traffic may withstand some delay in its service from its arrival. Six heuristic algorithms are developed by using three resource allocation schemes associated with both core-classified and non-core classified approaches which are presented in this paper. Extensive simulation experiments are conducted using three well-known network topologies and the performances of the heuristics are evaluated in terms of bandwidth blocking ratio, total energy consumption, and resource occupation rate versus traffic load as well as percentage of AR connections in multiclass traffic.
