This paper introduces the dissemination of Hybrid cost calculated for each route in Emission Aware and SLA Based Routing Mechanism as path attribute for purpose of inter-domain routing operation. This paper then compares the performance of the routing mechanism using this method against performance of the routing methods using other types of transmitted metrics such as energy code.
