问题描述
我已阅读完整的RFC 2030,其中描述了简单的网络时间协议.现在,我正在使用C语言实现sntp客户端和服务器.
我的疑问是如何计算根延迟,根分散和精度. sntp服务器将如何通过使用引用标识符来联系无线电时钟或其他同步源.我想将sntp客户端消息格式的轮询间隔设置为5,然后将其发送到sntp服务器,然后服务器将如何与sntp客户端联系5次.请给出所有这些事情的详细描述.
I have read complete RFC 2030 which describes abt simple network time protocol. Now I am implementing sntp client and server using C language.
What''s my doubt is how can I calculate root-delay, root-dispersion, precision. How sntp server will contact the radio clock or other synchronization source by using reference identifier. I suppose to set poll interval as 5 in sntp client message format, then I would send to sntp server, then how server will be able to contact sntp client 5 times. Please give detailed description about all these things.
