Biobjective VoIP Service Management in Cloud Infrastructure

Algorithm 1

Best fit (BFit).

Input: Voice node list (VNlist) and call.

Output: Allocation of call in one voice node.

() Sort VNlist by utilization on decreasing order.

() assigned false

() node_index 1

() Do

()   node_voice get(VNlist, node_index)

()   Add call to node_voice

()   if utilization of node_voice <= 0.7 then

()    assigned true

()   else

()    remove call from node_voice

()    node_index node_index + 1

()   endif

() While (size of VNlist >= node_index and

()   assigned = false)

() If assigned = false then

()   Create new_node_voice

()   Add call to new_node_voice

()   Insert new_node_voice into VNlist
