2. tcp 或udp收发缓冲区最大值 [root@ www.linuxidc.com]# cat /proc/sys/net/core/rmem_max 131071 131071:tcp 或 udp 接收缓冲区最大可设置值的一半。 也就是说调用 setsockopt(s, SOL_SOCKET, SO_RCVBUF, &rcv_size, &optlen); 时rcv_size 如果超过 131071,那么 getsockopt(s, SOL_SOCKET, SO_...
通过合理设置Payload大小和利用Window Size进行流量控制，TCP协议能够在不同的网络条件下实现高效、可靠的数...
实际在 TCP 分析中,关于 TCP Window Full 的定义非常简单,如下,为本端发送端所发的 TCP 段大小超过对端接收端的接收窗口大小,受到对端接收窗口大小的限制,需注意的是这个标记是在发送端标记,而不是在接收端标记。 Set when the segment size is non-zero, we know the window size in the reverse direction...
既然当前案例里 TCP Window Full 的时候,Bytes in flight 跟接收窗口相等,那么在这个公式里的窗口,是否就是 Bytes in flight 呢?我们来验证一下。 还是在 Wireshark 窗口里,我们要添加这么几个自定义列,以便进行数据比对: Acknowledgement Number:确认号 Next Sequence Number:下个序列号 Caculated Window Size:计...
The window size is still limited to 216or 65536 bytes,however, a new scaling factor option has been added to allow TCP to fully utilize higherbandwidths over satellite links. This new option is used to multiply the window size value foundin the TCP header window field to obtain the true ...
size of the maximum TCP segment size (MSS) negotiated during connection setup, up to a maximum size of 64 KB. TCP for Windows 2000 also supports windows scaling, as detailed in RFC 1323, TCP Extensions for High Performance. Scaling enables TCP to provide a receive window of up to 1 GB....
it sets the receive window size globally for all TCP interfaces. However, an entry with this name is in HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\interface-namehas precedence for the interface named in its registry path, and its value, rather than whatever value might be...
In TCP, the ___ timer is needed to handle the zero window-size advertisement.A) retransmissionB) persistenceC) keepaliveD) None of the choices are correct 相关知识点: 试题来源: 解析 B 在TCP中,当接收方通告窗口大小为0时,发送方会停止传输数据。为了避免因窗口更新报文丢失导致的死锁,发送方...

The TCPWINDOWSIZE option specifies, in kilobytes, the amount of receive data that can be buffered at one time on a TCP/IP connection. The sending host cannot send more data until it receives an acknowledgment and a TCP receive window update. Each TCP pac
