拿最常用的 4 层协议 TCP 来说,如果 MTU 是 1500,那么 IP 层就要保证 IP 层的 Packet 数据不超过 1480 bytes (1500 bytes – 20 bytes IP header), 对于 TCP 来说,它要保证每一个 Segment 数据大小不超过 1460 bytes (1460 bytes – 20 TCP header). 那么TCP 层要怎么知道 2 层的 MTU 是多少呢?
特别是在某些链路上,例如 VPN 和隧道接口,MTU 值可能小于标准 Ethernet 帧,因此 clamping MSS 是一种常见的做法。 示例命令 假设您想要将此规则应用于您的系统,可以在终端中输入以下命令: ip6tables-A FORWARD-p tcp-m tcp--tcp-flags SYN,RST SYN-j TCPMSS--clamp-mss-to-pmtu 请注意,在使用此命令之前,...
Why would I request that (1500 bytes MTU) while there is TCP MSS clamping?! Unfortunately i have come to understanding that enabling Mikrotik's TCPMSS Clamping PPP profile in addition to IPv4+IPv6 clamp-to-pmtu rule;does not work in both ways. How did I find that? Added filter rule wi...
MTU最佳是自动，正常情况下会根据下层设备设置ppp接口的MTU。然后开启MSS Clamping，会根据接口的MTU自动...
This is because the physical interface will see IPsec-encrypted packets, not TCP packets, and MSS clamping will not apply to those. A few questions regarding this: What or is there a command that could be run on the ASA to see the current MSS value of the IPSEC tunnels? Since our ...
UniFi – Enabling UPnP on Ubiquiti Security Gateway / Adjusting MTU and MSS Clamping 文章结合安徽省SDH专线网络建设的实践经验,对复杂网络中影响传输性能的MTU值和MSS值设置等因素进行了分析、研究,并提出了优化解决方案,从而解决了运行中发现的问题,提... GNaschenweng 被引量: 0发表: 2017年 MTU/MSS导致网...
UniFi – Enabling UPnP on Ubiquiti Security Gateway / Adjusting MTU and MSS Clamping This paper compares throughput performance of TCP and SCTP in a variety of network environments. For experiments, we construct a Linux-based testbed and consider a set of performance metrics such as MSS(Maximum ...
