Elephant Flow Detection Mechanism in SDN-Based Data Center Networks

Algorithm 1

Process of ADU-Server.

	Input: Packet_in
	Output: elephant flow info
(1)	When wait for Packet_in
(2)	If package.src_ip == ADU-IP
(3)	data = getTcpData (package)
(4)	elephant_flow.src_ip = data [0: 3]
(5)	elephant_flow.size = data [4:]
(6)	return elephant_flow
(7)	Else
(8)	return NULL
