Multi SLA Aware Green Provisioning Mechanism for WDM Networks

This paper introduces a simple mechanism which attempts to reduce the energy consumption and corresponding Co2 Greenhouse Gas (GHG). This mechanism couples an emission reduction method with multiple service provider Service Level Agreements (SLAs) to ensure an acceptable Service Level Satisfaction (SLS). This purpose is accomplished by formulating and solving a multi-constrained optimization problem. The results show emission reduction with acceptable SLS. This mechanism can be used in different control environments, such as Software Defined Networks (SDN) or Generalized Multi-Protocol Label Switching (GMPLS).
