Hi all,
 I am Shikha Thakur pursuing post graduation from Pune University in  Computer Engineering.Recently, I started my research in Xen hypervisor for my curriculum project.I am enjoying working with Xen. Being newbie i want to get more familiar with Xen.

So, I request all please tell me that my idea for this research is valid or not?

Research Topic::
I am working on "Improving Network I/O virtualization of Xen for Cloud Computing."

Xen Hypervisor ::
 The driver domain based model of Xen for network I/O virtualization exhibits poor networking performance.Two Experiments are carried out and they are:-

1)Network Performance analysis has been carried out to analyze the virtualization over- head and analyze the baseline reception, transmission and forwarding performance of the VMs(shown in fig 1).

2)Experiment has carried out to find the hardware bottlenecks and it is observe that the memory latency is the problem for costly driver domain - virtual machine communication (shown in fig 2).

Inline image 3Solution::
  As Memory latency is the bottleneck,Can Packet aggregation be applied to overcome this?

I would be awaiting for the reply.

Many Thanks.
