This paper investigates the virtual machine packing problem in cloud data centers. A cloud tenant expresses computation requirement for each virtual machine (VM) and bandwidth requirement for each pair of VMs. A cloud provider places the VMs and routes the traffic among the VMs in a way that minimizes the total number of servers used while providing both computation and bandwidth guarantees. We formulate...
Streaming media applications require acceptable levels of quality of service (QoS). Appropriate rate control mechanism is needed to make streaming media applications to adapt to dynamic network conditions. This paper discusses a window-based weighted-fairness AIMD (WF-AIMD) congestion control algorithm which allows competing flows to share a common bandwidth according to their weights. By making flows...
