1 Gigabit 以太网中的巨型数据包 - 帮助
我想了解 1 Giga 以太网中使用 UDP 的巨型数据包。
这种系统有哪些延迟？
我考虑在我的系统中使用巨型数据包，因为我需要在两台计算机之间传输大量数据。
我试图查找有关延迟的信息以及使用 1 GB 巨型数据包的缺点是什么 - 但我没有找到很多。 （我发现很多优点，但我也想知道缺点）
非常感谢您的帮助，
I would like to know about Jumbo Packets using UDP in 1 Giga etherent.
What are the delays in such system?
i think of using jumbo packets in my system because i need to transfer a lot of data between 2 computers.
i tried to find information about the delays and what are the disadvantages using jumbo packets in 1 gigabit- i didn't find a lot.
(I find many advantages but i would like to know also the disadvantages)
Thank you very much for the help,

您实际遇到的最大问题是硬件不支持巨型帧。请记住，如果您有一个大型网络，不支持巨型帧的交换机或路由器将丢弃它们，因为标准以太网帧大小是 1518 个八位位组 - 不知道巨型帧的硬件将假设之后的内容八位字节数是数据的 CRC，在不匹配后丢弃该帧。
此外，据说较大的帧可能会损害需要短响应时间的多媒体应用程序。这对我来说似乎很奇怪，因为将最大 MTU 设置为大于标准的值不会改变接口上的最小帧大小，因此仍然可以安全地发送小帧。
The largest problem that you can actually run into is the hardware not supporting the jumbo frames. Keep in mind that, if you have a large network, switches or routers which don't support jumbo frames will drop them, since the standard Ethernet frame size is 1518 octets - hardware that's not aware of jumbo frames will assume that what follows after that number of octets is the CRC of the data, and drop the frame after getting a mismatch.
Also, it is said that larger frames may hurt multimedia applications which require short response times. This seems rather weird to me, because setting the maximum MTU to something larger than the standard doesn't change the minimum frame size on an interface, so small frames can still be safely sent out.
