  1. SDN in GENI: Outbrief Marshall Brinn, GPO July 11, 2012

  2. Discussion • What are the mechanisms for creating a ‘sandbox’ for experimenters? • What are the mechanism for an experiment to program the network within that sandbox? • What are the constraints on that sandbox? • How can we provide performance isolation in that sandbox? • The session consisted of: • Three very thought-provoking presentations by: • Joe Mambretti of ICAIR • Ilia Baldine of RENCI • Nick Bastin of Big Switch • Followed by very spirited, engaged discussion

  3. Discussion Summary • Remarkably, there seemed to be consensus on several high-level principles (“I agree with Nick”) • The GENI infrastructure should provide transport which is independent of the virtual programmable substrate provided to the experimenter • Not along side, but on top, using some ‘encapsulation’ • We should seek to maximize performance isolation • We should seek to minimize constraints on the experimenter’s view/control of the network as possible We agreed that we need a concentrated period of design and prototyping to determine a reasonable technical approach to capture (approximate) these principals, ideally within the current and envisioned H/W baseline.
