Evaluating the Applicability of Bandwidth Allocation Models for EON Slot Allocation (1904.07862v1)

Abstract: Bandwidth Allocation Models (BAMs) configure and handle resource allocation (bandwidth, LSPs, fiber, slots) in networks in general (IP/MPLS/DS-TE, optical domain, other). In this paper, BAMs are considered for elastic optical networks slot allocation targeting an improvement in resource utilization. The paper focuses initially on proposing a BAM basic configuration parameter mapping suitable for elastic optical circuits. Following that, MAM, RDM and ATCS BAMs are applied for elastic optical networks resource allocation and the overall network resource utilization is evaluated. A set of simulation results and BAM behaviors are presented as a proof of concept to evaluate BAM applicability for elastic optical network slot allocation. Authors argue that a slot allocation model for EON based on BAMs may improve utilization by dynamically managing the aggregated traffic profile.
