目前,针对应急通信网络的新形势,新特点,设计了以IXP425网络处理器为核心的数据应用采集卡,该板卡集成PCI接口同时具备了网卡的相关功能,可以链接到主机中用于网络通信系统。系统采用SNMP协议和网络探针两种方式采集网络的状态信息,在实际应用中该系统性能相对稳定,采集的数据可靠性也较高。 At present, according to the new situation and new characteristics of emergency communication network, a data acquisition card based on the IXP425 network processor is designed. The PCI interface integrated with the card has the functions related to the network card and can be linked to the host for network Communication Systems. The system uses the SNMP protocol and the network probe to acquire the state information of the network in two ways. In practical applications, the system performance is relatively stable, and the data collected is also highly reliable.
