Your application should be written on the assumption that it is
possible, regardless of the specifics of the hosts involved,

Hi,
If I write UDP datagrams 1,2 and 3 to network and if the receiver receives in
order 2,1, and 3, where can the sequence get changed? Is it at the source
stack, network transit or destination stack?
Any reply is highly appreciated.
Thanks
Rajib
network transit. different datagrams might go through different
routes, hence the out-of-sequence arrival.

Yes. :)
Although network transit is by far the most likely case.

Does this mean if we have 2 hosts connected back to back (there's no
network device in between), sequence is guaranteed even in UDP?
Not true. Even for back to back systems SMP can cause packets
to be delivered out

I think if you're trying to make the packets appear in order you need
to untie the Gordian knot
