  1. GENI Summer Camp Project Team Member: Xinjie Guan, University of Missouri Kansas City; XiliWan, University of Missouri Kansas City; RuilingGao, Tufts University; Date: June 2, 2012

  2. Background -- OpenFlow White Paper

  3. Project Target • Investigate the impact of unknown flows • Computational resources on controllers • Network resources

  4. What We Have Done • Build the network topology • Reserve two nodes: one in GPO, another in Clemson • Reserve an additional node in protoGENI to play as the controller • We choose a protoGENI node to be the controller since it can be dedicated ONLY for our project • We use flake to reserve this node and configure it as controller in request rspec file • Reserve network resources: set one datapath (VLAN 3715)

  5. What We Have Done • Insert traffic • Install traffic generator -- iperf • Generate UDP packets

  6. What We Have Done • Observe CPU changes on controllers (Pox) • Pox costs the majority of the CPU source • 300 flows in one second can crash the Pox Started Pox Insert traffic with Iperf Without Pox

  7. Future Plan • Change the rate of unknown flows • Change the network topology • Observe switch performance • Next – • What can we do to limit the impact of large number of flows
