分片头部用于IPv6源节点向目的节点发送一个大于路径MTU的数据报。对于路径MTU以及如何确定它,以后有机会在提,1280字节是整个网络中针对IPv6定义的链路层最小MTU(见[RFC2460]的第五节)。在IPv4中,这个值可能是576。在IPv4中,如果数据报大小超过下一跳MTU,任何主机或路由器可将该数据报分片,IPv4头部中第二个32位...
技术标签:IPv6Fragment Header for IPv6 上一篇博客介绍了IPv6扩展头部的路由头部类型,这篇博客介绍一下更常见的扩展头部分片头部。 分片头部用于IPv6源节点向目的节点发送一个大于路径MTU的数据报。对于路径MTU以及如何确定它,以后有机会在提,1280字节是整个网络中针对IPv6定义的链路层最小MTU(见[RFC2460]的第五节...

IPv6 modified the handling of fragmentations and introduced a specific extension header, not solving the related problems, as proved by extensive literature. One of the primary sources of problems has been the overlapping fragments, which result in unexpected or malicious packets when reassembled. To...
Parts of ipv6 are fragmentable such as the authentication header while others such as the routing header are not. Note: Despite popular opinion saying otherwise, ipsec is actually not mandatory in ipv6. One must also be careful with the fraggle rock header - j/k - was making sure you're...

Partners can specify a maximum length for SMS messages. This requires setting both the maximum number of SMS fragments per SMS message, from 1 to 255, and the maximum size in bytes of each SMS fragment, from 16 to 140 bytes.Values
