It would probably be worth a reasonably long slot=20 to present this (20mins or more?). We will also=20 be asking to present it in the tcpm where it=20 addresses a chartered IETF work item, but we=20 ought to present its "research enablement" angle in more depth in the IRTF. The original problem we addressed was motivated=20 by the flawed feedback scheme in DCTCP and the needs of ConEx. However, we have designed it to be a generic=20 feedback reflector that will allow new sender=20 behaviours to be deployed unilaterally without=20 having to deploy new receiver behaviour each time=20 too. We're looking for feedback on whether it is=20 generic enough for all the ideas people might=20 have for using it (I'm working on 5 myself).

Title: Network Virtualization Infrastructure (NVI): A Scalable and Interoperable Cloud Network

Abstract:
Today’s technologies for constructing large scale cloud network, or “virtual private cloud” (VPC), unanimously resort to network tunnel protocol technologies by labelling and encapsulating network packets. This style of tunneling has a strong flavor of physical wiring hardware machines, really belonging to pre-cloud networking for physical machines. Unfortunately, packets labelling/encapsulation based tunneling technologies have quite poor scalabilities and probably little hope for cloud interoperability as a result that a tunnel protocol is forced to run at fixed "virtual tunnel endpoints (VTEPs)" . Cloud computing as service must operate in economy of scale and therefore follow the established principle of distributed computing for scalability. We propose a novel network virtualization technology: Network Virtualization Infrastructure (NVI). NVI creates and maintains context flow based virtual channel for communication nodes only when they are in communication. Without physical wiring style of tunneling, can not only network forwarding resource in NVI be better utilized, but more importantly cloud overlay networks be decoupled from the underlying physical network, e.g., be decoupled from fixed "virtual tunnel endpoints" like traffic hot and/or choke points. These properties translate to an unbound scalability and interoperability for cloud networks.
