Wed 09/24 (week 4) Network Virtualization



  • Is there any reason that the research network should be distributed across the world?
    –> In a large country, such as America, the time of different province may be different. Think about DTN deployment scenario.

Difference from previous systems such as NOS or ONIX is that the user of FlowVisor does not need to consider about other users. That is because previous systems run multiple applications on single controller but FlowVisor supports multiple controllers. In an one word, virtualization.

Why we should use FlowVisor instead of Emulab or VINI? –> You can do distributed system experiments but no network experiment since all the nodes are end-nodes not switches or routers.
