针对当前在网络传输中普遍存在的延迟问题,结合Wireshark的抓包分析技术来解析基于TCP协议的可能出现的延迟成因。不同的延迟情况,在网络线路、客户端以及服务端所表现出的特征是不同的,特别是在数据包的传输时间方面,在TCP三次握手前后,会表现出显著差异。这样就可以依据传输时间的差异来定位出网络延迟的成因,从而进行进一步检测,以排除网络问题,让数据更好地进行传输。 Aiming at the current delay problem in network transmission, Wireshark’s packet capture analysis technology is used to analyze the possible causes of delay based on TCP protocol. Different delay situations show different characteristics in network lines, clients and servers, especially in terms of data packet transmission time, before and after TCP three-way handshake. In this way, the cause of network delay can be located according to the difference of transmission time so that further detection can be performed to eliminate network problems and allow data to be transmitted better.
