An Active Controller Selection Scheme for Minimizing Packet-In Processing Latency in SDN

Algorithm 1

ACS active controller selection algorithm.

	REQUIRE: //set of controllers and their corresponding server load, server load is a set which includes response time and packet-in queue length
	REQUIRE: client inputs:
	//request list, m is the size of the list

(2)	m  sizeof(V)
(3)	2m randomly selected member from V
(4)	sortedList  sort in decreasing order of ServerLoad
(5)	while do
(6)	K
(7)	L
(8)	-K
(9)	(
(10)	[]
(11)	[]
