An improved energy efficient quality of service routing for border gateway protocol

Global routing performance and saving energy are critical for Internet applications. Internet service providers use the internal Border Gateway Protocol for the distribution of external routes within the autonomous system. The balance between the trade-off relationship of energy efficiency and quality-of-service is necessary for autonomous systems in green networking. Past studies have shown that energy saving schemes exacerbate quality-of-service. However, the optimum use of resources balances the trade-off between energy efficiency and quality-of-service. Therefore, we propose a Green BGP model that balances the trade-off between energy efficiency and quality-of-service by optimizing the internal Border Gateway Protocol path selection policy. Border Gateway Protocol routers select a path considering the quality-of-service attributes and energy efficiency of the path within the autonomous system. The proposed model is compared with related techniques, and the results confirm the advantages of the Green BGP model that improves energy efficiency and maintains quality-of-service.
