Virtual cluster is a useful resource descriptive model, in terms of virtual machines (VMs) and link bandwidth, for many data center applications that require predictable performance. Bandwidth-constrained data centers often use reservation schemes to statically allocate underlying physical resources to virtual clusters. However, due to highly varying workloads, existing reservation schemes may place VMs improperly, causing a waste of bandwidth reservation and eventually leading to rejecting new… CONTINUE READING
