Data-Intensive Cloud Control for GENI: Processing Weather Radar Data on Amazon EC2

Demo Participant: Emmanuel Cecchet
This demo will show how Orca can be used to manage Amazon Web Services (AWS) resources including servers (EC2) and storage (S3). Data from a weather radar will be uploaded to S3 and processed by an EC2 server to produce images. A limited budget of AWS resources will be allocated and the processing will stop as soon as the budget limit has been reached. This will showcase the DiCloud? proxy aggregate manager for Orca.

GENI Pathlets

Demo Participants: Mark Berman, Brighten Godfrey
Source-controlled routing is a promising architectural approach to improve reliability, efficiency, and overall flexibility of the network. We will demonstrate a streaming media application weathering "storms" on the network via source-controlled adaptive routing, running on top of pathlet routing, a flexible interdomain routing and forwarding substrate.

NetServ (GENI Alpha project)

Demo Participants: Jae Woo Lee, Jan Janak, Roberto Francescangeli, Suman Srinivasan, Salman Baset, Eric Liu, Michael Kester and Henning Schulzrinne
We present NetServ, an extensible platform for deploying in-network services. NetServ-enabled network nodes provide a common execution environment, where network services implemented as modules can be dynamically installed and removed. Our demonstration shows how NetServ can help solve some of the issues faced by content and real-time service providers. We show how NetServ-enabled nodes can help content providers disseminate content and how providers of real-time services, such as voice and video calls, can use NetServ-enabled nodes to make their systems more scalable and reliable. GENI allows us to deploy NetServ-enabled nodes in the network.

OpenFlow at Stanford: Packet and Circuit Convergence

Demo Participants: Saurav Das, Yiannis Yiakoumis
Packet and Circuit switched networks are typically planned, operated and managed separately, leading to substantial management overhead, functionality & resource duplication, and increased Capex & Opex. We propose and demonstrate a converged network, where OpenFlow is used to control both switching technologies in a common way, allowing the service provider maximum flexibility in using the correct mix of technologies while designing and operating their networks. Specifically, we will demonstrate how circuit flow properties (guaranteed bandwidth and delay, no jitter, bandwidth-on-demand) can be used to provide differential treatment to different types of aggregated packet flows - voice, video and web traffic.


Demo Participant: Jad Naous
We started by asking the question, "Is there a simpler control framework that has a milder learning curve and that is less complex and brittle than today's GENI control frameworks?". Expedient provides a pluggable control framework that leaves the specification of APIs to the resource developers themselves. It simplifies authorization and authentication, and allows resource providers to choose to delegate these operations to Expedient if they want to. It allows developers to design rich user interfaces by providing access to an object-oriented database that describes resources and aggregates.

The demo shows federation of PlanetLab and OpenFlow resources at Stanford with similar resources at BBN, and the ability to create a slice that spans these resources through a user interface plugin. Links:

OpenFlow at Stanford: Aster*x

Demo Participant: Nikhil Handigol, Srini Seetharaman
Effective load-balancing systems for services hosted in unstructured networks need to take into account both the congestion of the network and the load on the servers. In this demonstration, we illustrate a comprehensive load-balancing solution that works well for such networks. The system we showcase, called Aster*x, tries to minimize response time by controlling the load on the network and the servers using customized flow routing. The demonstration shows how Aster*x works over a combined network and computation slice spanning multiple campuses across the country. Besides the base behavior, we show the effect of dynamically adding and removing computing resources to the system, increasing the request arrival rate, altering the CPU or network load of each request, and changing load-balancing algorithms. Collaborating campuses: UWash, Indiana, Princeton and BBN

OpenFlow at University of Wisconsin: Mobile Application Migration in Enterprise Metworks

Demo Participants: Aaron Gember, Aditya Akella
Smartphones are becoming an important element of enterprise computing, but new applications are putting increased demands on limited hardware resources. We propose an offloading framework that takes advantage of local resources in enterprise networks to simultaneously address the resource, performance, and security demands of mobile applications. We demonstrate the application migration component of our in-progress offloading system prototype. An application is launched on a Google Android smartphone, then migrated to an idle desktop (laptop) over an OpenFlow network. We also demonstrate offloading applications to a remote cloud by offloading a running application from the smartphone to the University of Wisconsin-Madison campus OpenFlow network.

OpenFlow at University of Wisconsin: Packet Level Redundancy Elimination (RE) on Network Elements

Demo Participants: Ashok Anand, Aditya Akella, Athula Balachandran, Srinivasan Seshan
Internet traffic is increasing at a tremendous rate. We propose a framework of deploying packet level redundancy elimination (RE) on network elements (e.g., routers) ) and show that it can serve as an effective way to improve network efficiency without expensive upgrading of network links to higher bandwidths. In the demo, we first show the current scenario of Internet video transmission in terms of link loads.We then show the impact of RE, and how it reduces link loads by eliminating redundant content. We have RE enabled software routers, which are configured by a Nox controller.

Specifically, we will show how early experimenters can setup and use the OnTimeMeasure software in their own ProtoGENI slices. We will also show the newly developed/enhanced features (e.g., researcher web-portal, user slice registration, distributed on-demand measurement, centralized on-going measurement, handling monitoring objectives, user customizable dashboard, admin interface). Lastly, we will show our early efforts in integrating the OnTimeMeasure software with other GENI projects such as Instrumentation Tools (Integration screenshots).

ORCA/BEN: A Prototype GENI Control Plane (ORCA) and a Metro-Scale Optical Testbed (BEN)

Demo Participants: Ilia Baldine (RENCI), Yufeng Xin (RENCI), Anirban Mandal (RENCI), Namgon Kim(GIST), Anjing Wang (NCSU), Michael Wang (Columbia), Balagangadhar Bathula (Columbia)
We demonstrate:

  • Capabilities of ORCA control framework to create cross-site slices using resources from multiple distributed resource providers (BEN, Duke University, NLR, StarLight facility, UMass Amherst). The slice is stitched from VMs on Duke campus, multiple VLAN segments and another VM at UMass Amherst that collects sensor feeds from ViSE testbed. In this demo ORCA actors (authorities, brokers and experiment controller) exchange NDL-OWL formatted substrate descriptions and requests to form the slice.
  • Capabilities of ORCA to provision OpenFlow slices: ORCA provisions OpenFlow slice on OF testbed located in Korea and connects them to VMs running in BEN network (North Carolina). The experiment demonstrates an OF controller capable of performing VLAN translation.
  • We show a poster and demo for GENI-IMF project demonstrating integration of physical layer measurement capability and programmatic in-stack (protocol stack) consumption of such measurement data for cross-layer control. Physical layer measurements from BEN network are relayed via pubsub IMF system to an application running experimental SILO modular networking protocol stack. The SILO cross-layer controller consumes the measurement data and is able to dynamically control the SOA (Silicon Optical Amplifier) on the link connecting the two parts of the application. This dynamic control allows the application to actively compensate for the loss of power on the link introduced by a programmable attenuator.
