变电站综合信息传输中的网关流量管理实现

Gateway-based flow management realization of integrated information transmission in substation

为解决变电站综合信息传输中的流量冲突问题,设计了基于Linux平台的网关流量管理系统。分析了变电站综合信息业务类型,提出依据各种信息的QoS(Quality)要求,对不同的信息流规范其传输带宽和优先级。系统阐述了Linux平台的流量管理机制,并给出变电站综合信息传输中的网关流量管理的具体程序实现。经系统实测表明,该网关流量管理系统可以有效解决变电站综合信息传输中的流量冲突问题。

In order to solve the problem of flow collision in integrated information transmission of substation, this paper proposes a Linux-based gateway flow management system. The types of integrated information are analyzed, and the bandwidth and priority grade are set by the information flow management system according to the QoS requirements of information transmitting. The principle of Linux-based flow management is expatiated, and the realization of gateway-based flow management in integrated information transmission of substation is explained in detail. Also,the programming code is given. The relevant test indicates that the proposed flow management system can effectively solve the problem of flow collision in integrated information transmission of substation.
