Some suggestions for the nature of the experimentsThis is a featured page

  1. Regarding the topology of a network of virtual machines:
    • We know that we can organize the VM's within different subnets and in combination with how the machines are connected to each other, we effectively control the topology of the network. Given this, one particular control factor could be, by actively changing the topology of the network and observing the flow of traffic. It'd be interesting to try and find if any particular kind of topology facilitates greater efficiency in packet traffic flows, i.e. would a certain kind of network topology make the forwarding of packets easier? One particular way of approaching this experiment might be to expose the network to a controlled flooding with Link State Packets.
    • From an algorithmic viewpoint, it might also be interesting to compare different methods of producing a Minimum Spanning Tree (by Dijkstra's, Prim's, etc.) and see how they react to an evolving network topology.

  2. Looking at the working of TCP:
    • By controlling the exchange of packets and systematically introducing the phenomenon of packet loss; perhaps we can do a comparative analysis of Go-Back-N versus Selective Repeat. Would there be a difference? If so, can we extrapolate something about the nature of these protocols and their efficiency?
    • It would also be interesting to set up the VMs and have them interact in such a way so that we can perhaps come up with some new control variables or stricter bounds upon the estimation of Round Trip Times.

  3. Security Issues: It would be interesting to have the VMs behave as routers and explore ways in which we can fool the routers into forwarding datagrams incorrectly or drop them; and subsequently how could such situations be rectified?
  4. Routing Issues:If we have our VMs simulate routers, we can perhaps explore how datagrams are managed within the switching fabric of the router.
