That's a pretty vague question. In what context? What protocol are you
talking about?

If you're talking about TCP, in a reset packet, the RST bit in the header
is set. In an Ack packet the ACK bit is set.

Iam talking in the sense of programming, when received a packet in my
program it strips off all the header content, then how can I know the
packet is a RST packet

You just have to check if the RST bit (which is, i think, the 142 bit in the tcp header) is 1 or 0.
