Still, transfer others to write well.

Here are some of my additions:

Although the maximum length of ip packets can reach 65535bytes can be defined in the header of ip, the maximum length of IP packets is generally 1500bytes, that is, MTU (maximum transmission unit).

When the MTU is large enough (jumbo frame is generally defined as 9000bytes), the disassembly of ip packets will be reduced, but this is generally not recommended for several reasons: 1. Not all network devices support such a large MTU, such as the early device MTU or 1492 bytes. The larger the packet, it means that there will be a big delay in data transmission.
