用wireshark抓一下我博客的包,可以看到TLS1.2中需要两个RTT(round-trip time)来完成握手, (这里TCP segment of a reassembled PDU是指tcp对过大的数据分包发送,wireshark用此来标记同一个包,我把其他隐藏了方便看) 过程: 客户端向服务器发出请求,提过支持的密码算法列表, 服务器收到后决定加密和散列函数,发送...

摘要:TCP segment of a reassembled PDUTCP segment of a reassembled PDU是什么意思,其实主机响应一个查询或者命令时如果要回应很多数据(信息)而这些数据超出了TCP的最大MSS时,主机会通过发送多个数据包来传送这些数据(注意:这些包并未被分片)。对wireshark来说这些对相应同一个查询命令的数据包被标记了“TCP segme...
