摘要
传统的数据上报,大多采用发送方作为客户端,向上级服务器发起连接请求,采用主动推送的方式完成数据传输。当电站数量巨大且上报数据种类和通信条件都不尽相同时,这种方式无疑为上级服务器打开了一个后门,带来了一定的安全隐患。提出了一种接收方发起的电站数据传输控制方法,由上级数据中心发起请求、电站响应并完成数据传送的反向拉动模式,使得中心侧不再暴露通讯端口,降低了中心侧网络遭受攻击的可能性。有此,设计了配套的应用层数据可靠传输协议ADRTP(Application-layer Data Reliable Transport Protocol),通过一系列控制机制和调整最大数据包长度L_(max),提高数据传输的效率。
Traditionally,data uploading mostly uses the sender as a client to initiate a connection request toward the upper-level server by using the active PUSH to complete the data transmission.However,when there are a large number of power stations and various types of data with different communication conditions,this way undoubtedly opens a back door for the upper-level server,which brings certain security risks.In this paper,a receiver-initiated method is proposed for power station data transmission control,in which the upper-level data center initiates the request,the power station or branch center responds and completes the data transmission in a reverse PULL mode.The communication port on the central side is no longer exposed,which reduces the risk of the central side network being attacked.Consequently,the Application-layer Data Reliable Transport Protocol(ADRTP)is designed to improve the efficiency of data transmission through a series of control mechanisms and adjusting the maximum packet length Lmax.
