GEINIVIOLIN: In-Network Suspend and Resume for GENI Experiments

1. Brief demo description

GENI-VIOLIN's goal is to build an In-network suspend and resume infrastructure for GENI experiments. This project is part of the GENI-alpha plenary session for GEC9. Current GENI experiments cannot be suspended/resumed, and often have to be restarted from beginning, if failures occur in the infrastructure. GENI-VIOLIN solves this problem, by providing "live snapshot" capability to GENI experiments running in GENI slices for fault tolerance, debugging and slice management. GENI-VIOLIN provides the suspend/resume functionality to GENI experiments, with minimal disruption to application performance, while being completely transparent to the application and guest operating systems.

During GEC9, we will show suspend/resume functionality that is completely in the network by exploiting Openflow. GENIVIOLIN requires minimal hypervisor support from the end-hosts. We will show a demo of suspend/resume over two sites (Utah and BBN Emulabs) that are geographically separated.

2. List of equipment that will need AC connections (e.g. laptop, switch hardware prototype, monitor). (Just put in the number of connections needed if your demo description already lists the equipment)

3 laptops, 2 monitors

3. Number of wired network connections (include required bandwidth if significant)


4. Number of wireless network connections (include required bandwidth if significant)


5. Projector (y/n) Monitor (y/n, specify VGA or DVI. Specify resolution only if your software has resolution restrictions) Bring your own projectors if feasible.

Projector - y Monitor - y

6. Number of posters (poster boards are 20" x 30")


7. Number of static addresses needed (if any)


8. Description of any special requests (There will be no layer 2 I2 or NLR VLANS to the GEC9 demo floor--only production Internet service)
