改进流量性能的高可用性无缝冗余在变电站通信网中的应用
Application of High-availability Seamless Redundancy with Improved Flow Performance in Communication Network of Substation
摘要
Abstract
High-availability seamless redundancy is widely used in industrial control network but copy frames may be recycling in the network and returning to the originating node which is probably producing unnecessary flow,reducing network per-formance and causing jam or break-off of the network.Therefore,this paper proposes a kind of quick removing method to solve this problem that is to remove copy frames from the network when all network nodes have received copy frames of transmit frames and are going to accept another copy frame.By calculating,it proves that this method is able to effectively reduce redundant flow in standard HSR network and in limiting case,it is able to reduce about 50% redundant flow.Finally, by using HSR network with improved flow performance,it discusses establishment of high-reliability digital substation com-munication network.关键词
