Environment, caught the results are as follows:

Is my UDP packet is too small

On the package of it, there is no shard ah, would it make you change the nic mtu value is too large, the default should be 1500.

May be I use the same machine, there is no catch IP level package

CodePudding user response:

IPV4, click on the IPV4 Fragments could, you can see the piecewise situation,,

In theory, Mr Frame size is 1500 (standard maximum is 576), do not rule out 9000 jumbo frames, and take the example of 1500, 1500-20 (IP) - 8 (UDP)=1472, mean if ehter frame is 1500, more than 1473 will be divided, and you go to look at it, you must be shard

CodePudding user response:

MF have been position, MF is equal to 1, indicating some subsequent packets, so the paper bag is divided

MF have been, MF is equal to 1, indicating some subsequent packets, so the newspaper article is shard bag

this is the right way
