Title
Online lightpath provisioning and critical services: New IA-RWA algorithms to assure QoT and survivability
Abstract
Wavelength Routed Photonic (or all-optical) Networks (WRPNs) with an intelligent control plane will play a key role in providing the proper ground for future Internet applications. However, classic Routing and Wavelength Assignment (RWA) solutions are inadequate to be adopted by WRPNs. The main issues regard physical impairments and QoT, processing time and setup delay, lightpath (LP) survivability and minimization of resource allocation. In case of critical services provisioning, LPs must have tight QoT guarantees, even in case of network instability and failures. This work presents two new impairment-aware RWA (IA-RWA) algorithms, specifically tailored for the provisioning of critical services. These algorithms guarantee absolute bandwidth and Bit Error Rate (BER) for LPs, assuring survivability in case of single network failures. A high parallelizable, combined RWA engine minimizes resource utilization without increasing setup time. The performance of the proposed algorithms are evaluated with respect to a modified version of a previously proposed IA-RWA algorithm that takes into account QoT and survivability.
