Algorithm 2 Processing Data Packet
	OnData (data)
1	// Check whether the probe-response is empty. if data.probe-response != 0 then
2	// Check the probe in FIB  if FIB (data.probe) == 0 then
3	Create a FIB entry for data.probe
4	else Update the entries in FIB by data.probe-response

7	if PIT (data) != 0 then
8	if CS (data) == 0 then
9	Cache data
10	end if
11	if FIB (data) == 0 then
12	Create a FIB entry for data
13	else Update the entries in FIB by data
14	end if
15	Forward data, remove the entry named data in PIT and break
16	else drop data
