Scope

Ensure GENI includes the technology to support cross-layer communications, specifically, the ability to incorporate a diverse set of real-time measurements in networking protocols. The project addresses the GENI challenge of architectural experimentations across diverse heterogeneous technologies by supporting real-time cross-layer communications and measurements. Our objective is to develop networking capabilities within the GENI infrastructure that enable deeper exposure of cross-layer information and user access to real-time measurements.

Milestones

ERM: GENI requirements for real-time measurements Completed 3/1/09
ERM: Develop specifications and networking protocols Completed 3/1/09
ERM: Perform discrete-event network simulations Completed 3/1/09
ERM: Develop a software architecture Due 6/1/09
ERM: Support the GPO in developing an experimental use-case Due 9/1/09
ERM: identify a candidate control framework Due 9/1/09

Milestone 1:

The capabilities of GENI's (future) infrastructure with respect to real-time measurements are evaluated and we assess the GENI requirements for real-time user access to measurement data across a diverse set of technologies.

Technical Note MS1

Milestone 2:

A set of specifications for enabling real-time measurements within the substrate and specifications for networking protocols based on the GENI requirements for real-time user-accessed cross-layer measurements is developed. We identify a set of specifications for the implementation of a unified, integrated measurement framework with the ultimate purpose of limiting the hardware and software overhead and complexity associated with accessing measurement data.

Technical Note MS2

Milestone 3:

To enable and perform discrete-event network simulations and quantitatively evaluate performance impact under several scenarios of cross-layer information exchange based on real-time measurements we developed new simulation modules for the ns-2 open source network modeling environment and make them available to the GENI community:
