Hello I am working for my Msc thesis on computer engineering, my primary goal is to introduce scheduling with priorities over different networking interfaces, it can be very valuable on virtual machines like Xen and as far as i have studied, Xen is scheduling the virtual network interfaces in round-robin fashion, i would like to improve this and to use Deficit Round Robin, I think the better way is to integrate the DRR in tc and to make the scheduling based on virtual network interfaces which belongs to different guests as shown from the diagram in atach. I would like to ask which function on source code may be a starting point to realize that kind of scheduling? What are the opportunities to involve the DRR as a standard scheduler in tc for later use ? How can i use this scheduler or others in Xen Hypervisor to schedule different virtual network interfaces in Dom_0 backend, note that as a refernece point must be taken the vif(virtual network interface of a guest domain) not the flow. Kind regards Ronald
