| Abstract: | 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. |
