摘要
地震数据处理系统和分析系统对实时数据的高可靠性和低延时要求,决定了组建地震实时数据传输共享应用平台必须采用可靠性传输协议,并兼顾安全性。提出了采用改进的传输控制协议、虚拟专用拨接网络(VPDN)、带宽适应算法在CDMA1x网络中构建地震实时数据传输共享平台,将传输率提高了近10%,达到了99.95%,RTT延时从平均1200ms降到了250ms左右,满足了地震数据处理系统的要求。
Requiring high reliability and low delay of real-time data in earthquake data disposal system and analysis system, it is demanded to establish real-time data transferring and sharing platform with reliable transport protocol, and given attention to security. One solution is provided that utilizes enhanced TCP, VPDN, bandwidth adaptation algorithm to build the platform in CDMAlx networks, as result, it increases successful rate about 10 percent, reachesover 99.95 percent, reduces delay 1 200 ms to about 250 ms, and satisfies all requires about earthquake data disposal system.
