Abstract

This work investigates service provisioning mechanisms to guarantee Service Level Agreements (SLA) in Elastic Optical Networks (EON). The proposed Analytical Provisioning Algorithm of Critical Hop Edge (APACHE) reduces Blocking Probability and offers service providers greater control over modulation and the number of slots occupied in the frequency spectrum. The provisioning algorithm allocates network resources based on the specific needs of transmission in each Class of Service (CoS), improving application performance. For example, a video streaming application may require a large bandwidth to transmit high-quality video. In contrast, a voice-over IP (VoIP) application may require low latency to guarantee voice communication. The contributions of this work include the development of a fragmentation and free spectrum awareness algorithm to reduce Blocking Probability and offer better treatment for different CoS, in addition to modeling and improving a simulation environment for service provisioning in EONs. These contributions are relevant to improving the efficiency and quality of services, ensuring customer satisfaction and compliance with SLAs.
