SRAF: A Service-Aware Resource Allocation Framework for VM Management in Mobile Data Networks

Algorithm 3

System scheduling algorithm.

(1)	procedure CLASSIFICATION METHOD
(2)	Uses the SCA in Algorithm 1 to classify ;
(3)	Puts the into the corresponding line;
(4)	End
(5)	procedure MAIN
(6)	Initializes basic VMs into two types, the high-type VM line and the normal-type line;
(7)	while the system is running and in the beginning of an interval do
(8)	Monitors , of every VM;
(9)	Calls Algorithm 2 to determine the VM migration.
(10)	Calls Horizontal-scaling algorithm; //see Algorithm 4
(11)	Calls Vertical-scaling algorithm; //see Algorithm 5
(12)	end while
(13)	while ( is coming) do
(14)	CLASSIFICATION METHOD;
(15)	while there have tasks in the three lines do
(16)	Schedules the tasks from the video-focus tasks line and file-focus tasks line on the high-type VM by the sharing mode;
(17)	Schedules the normal task into normal-type VM;
(18)	end while
