Resource Allocation Scheme Based on Complete Planning Process for Immediate and Advance Reservation in SDM-EONs

Immediate reservation (IR) and advanced reservation (AR) become two common traffic models for future space division multiplexing-elastic optical networks (SDM-EONs). However, it is crucial to reduce conflicts between different types of requests and to accommodate more requests with limited resources...
