Improving Network I/O Virtualization for Cloud Computing 1 M.Srinivasulu

Abstract:Cloud computing is a latest technology that gives platform and software as a service. A cloud platform can be either virtualized or not. the cloud platform increases the resources availability and the flexibility of their management (allocation, migration, etc.). It also reduces the cost through hardware multiplexing and helps energy saving. Virtualization is then a more and interesting technology of cloud computing. System virtualization refers to the software and hardware techniques that allow partitioning one physical machine into multiple virtual instances that run concurrently and share the underlying physical resources and devices. Virtualization is a key technology to enable cloud computing. It enhances resource availability and offers high flexibility and cost effectiveness. In our proposed scheme allows us to dynamically tune the aggregation mechanism to achieve the best tradeoff between the packets delay and throughput. The proposed I/O virtualization model hence forth satisfies the infrastructure providers to offer cloud computing services. Here I/O virtualization model based on packet aggregation to transfer packets between the driver domain and the VMs. It will Improve networking performance of VM where the access to the network device is shared through the driver domain
