Abstract: Along with the expansion of Internet users and the innovation of Internet applications,the scale of the Internet increases rapidly.High performance and reliability requirements of the Internet will bring in the huge power consumption and inefficient energy usage,which increases operation costs of the Internet and restricts its scale.Moreover,the rapidly increasing carbon footprint of the Internet will aggravate global warming.Researchers have proposed many energy-saving technologies in the Internet.This paper first presents the significance,feasibility and research scope of energy conservation in the Internet;We then focus on studying the energy-saving technologies for routing devices and protocols in the Internet,and survey,analyze and compare some of typical schemes in details;Meanwhile,we propose the power consumption model of routing devices and leverage the tradeoff analysis to guide the research of energy-saving routing devices and protocols in the Internet;Finally,some open issues and future directions in this area are discussed.

Key words: energy-saving technology for routing devices, energy-aware routing protocol, power consumption model, data center network
