The WLC (Weighted Least-Connection) scheduling algorithm is a widely adopted scheduling algorithm in cloud computing systems. However, it has the following shortcomings: one is that using the WLC scheduling algorithm, it is not easy to modify the weight of each server instantaneously once it is determined; the other is that merely using the number of tasks connected to each server to indicate the server load is not accurate. In this paper, they propose a DWLC (Dual Weighted Least -Connection) scheduling algorithm, which is an improved algorithm based on WLC scheduling algorithm and overcomes the above mentioned shortcomings.
