Exploiting the Vulnerability of Flow Table Overflow in Software-Defined Network: Attack Model, Evaluation, and Defense

Algorithm 1

FIFO inference algorithm.

Require:

Packet-Sending Function: ;

List of IP: ;

Ensure:

The flow table capacity: ;

The number of other users’ flow entries: ;

while    do

SENDPACKET

if Flow table is full then

continue

end if

if One of our flow entries is deleted then

break

end if

end while

return ,
