Hi, Suhail
Do you want to get the total bytes with the Packet In header, or without
the header?
If you want to get with the header, msg_len returns the bytes including
its header.
You can get this filed and add it to the total count:
@set_ev_cls(ofp_event.EventOFPPacketIn, MAIN_DISPATCHER)
def _packet_in_handler(self, ev):
print(ev.msg.msg_len)
Or if you want to get without the header, FlowStats may be enough to get
the total byte count.
The "byte_count" in OFPFlowStatsReply represents the total bytes in a flow.
If you want to know only the total byte count, it may be enough for you.

Hi All,
At the moment I have modified my switch to use packet In for every
packet entering the switch. What i want to attain is to get flow
statistics for every packet.
Let me explain a bit. A flow keeps track of how many packets have
passed in a flow, also how many bytes have passed.
Now what my target is to get the bytes based on each packet.
For example, First packet comes in with 2 bytes, the second packet
with 3 bytes, so my byte count goes to 5.
Third packet of 2 bytes and byte count goes to 7. Is there a way to
track byte count and other statistics like this?
Regards,
