Switch supports rate and storm limiting functions,which have significant application value in the smart substation network.Based on an analysis of network structure,message types and the flow characteristics of the smart substation, problems brought about by the networked process layer and their solutions are discussed.The storm limiting function and its inadequacy are described,and the functional requirements for rate limiting of smart substation network are proposed.In accordance with the data processing flow chart of the switch,the rate limiting technology based on the content aware processor (CAP) and its features are analyzed in detail.The rate limiting solution based on CAP is verified through tests in the simulation environment of three-in-one net for smart substation.The prospects for application of the rate limiting solution in smart substation are discussed.
