Hi Sarvesh, Richard
In general any router is not supposed to re-order the packets, even when the
packets are received from outside.In this case, the packets are created
internally only. So as such UDP protocol makes no difference.
One reason i can think is the use of multiple queues, or threads for
transmission.

Hi Sarvesh,
UDP is not a reliable protocol, not even for the order of packets you receive.
You have to re-order them when you receive them. For example using a sequence
number to index them into a circular buffer.
Wireshark does not re-order UDP packets but merely shows them in the order they
were captured.

Richard
