“…Data center network research has become a popular aspect in academia and industry. Scholars have proposed many data center networks, for example, Fat-Tree [3], DCell [4][5][6], BCube [7,8], VL2 [9], CamCube [10], Ficonn [11], FSquare [12], BCDC [13,14], and so on. Because of its desirable features, such as symmetry, small diameter, high fault tolerance, and so on, BCube has become a main data center network.…”
