Abstract

Virtualization technology is the backbone of Cloud Computing. Virtualization provides efficiency, flexibility and scalability in cloud computing. Virtualization in cloud computing can be done through different virtualization platform such as VMware, Kvm, UMLinux, VirtualBox, Xen. Xen is an open source hypervisor; a virtualization tool for cloud computing that is widely used among cloud providers. Since, Xen yields poor throughput for network I/O virtualization. To overcome this problem; number of hardware and software enhancement solutions are proposed. Packet aggregation mechanism is one of the solutions that can improve the performance of driver domain based model of Xen. Packet aggregation mechanism results in increased throughput at a cost of maximized packet delay and jitter. Here is the proposed self-adaptive buffering jitter control mechanism that dynamically tunes the aggregation to achieve best trade-off between throughput and delay. It finds the mean release time of a container according to dynamic traffic load. Thus, an aggregated model of Xen would improve performance resulting in strong foundation of virtualization for cloud providers.
