tcp maximum segment sizeCoinvestigator, New
理论上来说是没错的,UDP中就不存在MSS,UDP生成任意大的UDP报文,然后包装成IP报文根据底层网络的MTU分段进行发送。MSS存在的本质原因就是TCP和UDP的根本不同:TCP提供稳定的连接。假设生成了很大的TCP报文,经过IP分段进行发送,而其中一个IP分段丢失了,则TCP协议需要重发整个TCP报文,造成了严重的网络性能浪费,而相对的...
Tcp Maximum Segment Size 【计算机】PPP模式中常用的名词(与联机速率有关,一般默认值为1460) Maximum Segment Size 最大区段尺寸指两个网络主机之间,彼此用来协调传输的最大资料量。 maximum segment address 【计】 最大段地址 maximum floatable size 最大可浮粒度 maximum limit of size 最大极限尺寸 re...
A. TCP_MAXSEG(Maximum Segment Size):它指定在TCP连接中所使用的最大分段大小(即每个TCP报文段中的数据大小)。通过调整该选项可以影响TCP连接的吞吐量和延迟。较小的分段大小可以减少网络拥塞情况下的丢包率和重传时间,但会增加协议开销。 B. TCP_NODELAY:该选项用于禁用Nagle算法,它可以提高小数据包的实时性,适用...
TCP最大传输段，简称MMS。就是一个TCP报文段的最大长度（包括TCP头部和TCP承载的数据）。MSS
MSS defines "segment" as only the length of the payload, not any attached headers. MSS is measured in bytes. MSS is determined by another metric that has to do with packet size: MTU, or the maximum transmission unit, which does include the TCP and IP (Internet Protocol) headers. To ...
MSS计算方式: THE TCP MAXIMUM SEGMENT SIZE IS THE IP MAXIMUM DATAGRAM SIZE MINUS FORTY.(RFC879) 即MSS = MTU - IP HEADER(20字节) - TCP HEADER(20字节) RFC6691关于MSS的说明: When calculating the value to put in the TCP MSS option, the MTU value SHOULD be decreased by only the size of...
MSS(Maximum Segment Size)指TCP段中应用层数据的最大长度,不包含TCP头部和其他传输层开销。题目明确指出"MSS指段中最大__层数据量",而非包含头部的整个TCP段大小。 选项分析: - A. 应用层:正确。TCP将应用层数据封装至传输层段中,MSS限制的正是这部分数据长度。 - B. 传输层:错误。传输层头部属于传输层自...
To resolve the ambiguity in the TCP Maximum Segment Size option definition the following rule is established: Postel THE TCP MAXIMUM SEGMENT SIZE IS THE IP MAXIMUM DATAGRAM SIZE MINUS FORTY. The default IP Maximum Datagram Size is 576.
So if the ip packet is 3000 bytes long,then network layer has to perform fragmentation of the packet in case of ethernet. The question remains what would be maximum data could be put in the tcp segment as it is data field 's size is not fixed. Thanks and have a great weekend. ...
