Scope

This project will develop and integrate the GENI Integrated Measurement Framework (IMF) for optical communication substrates into the ORCA control framework prototype, and integrate the FIND SILO framework into the ORCA control framework prototype, and IMF and SILO with each other, to enable cross-layer experimentation involving the physical layer of an optical network.

This will enable (a) measurements from an optical substrate to be passed to a measurement consumer inside a slice; this is a valuable capability since the optical substrate characteristics may be important to the experimenter in the slice although the substrate itself is not directly observable by the experimenter, and (b) enable the automated (in-stack) consumption of measurement data; this is important for an experimenter who does not merely want to see the optical substrate measurement data after the experiment, but would like to experiment with reactive protocols designed to run inside the stack and react in real-time to measurements.

Initial deployment will be in the Breakable Experimental Network (BEN), a regional optical network located in North Carolina.

The IMF will utilize deliverables from the Embedded Real-time Measurements (ERM) project, including its Unified Measurements Framework (UMF).

The IMF will provide a single point of access to various devices in the optical substrate. The IMF will include a software module that interfaces with the UMF to gather measurements from the optical substrate, and that communicates with SILO (and other software modules) over a specified communication protocol, also to be developed in this project.

The interface between the IMF and the optical devices in BEN will be leveraged from the UMF of the ERM project. The IMF will gather measurements from devices with performance monitoring capabilities already incorporated into the BEN, including: the Infinera DTN, a remotely configurable optical add/drop multiplexer (ROADM); and the Polatis 24 port fiber switch. This will be guided by the output of the Data Plane Measurements project, that identified measurement capabilities in a wide range of equipment. In addition, the use of programmable measurement nodes and performance monitors will be assessed.

The Services Integration, controL and Optimization (SILO) framework was previously developed and prototyped in the NSF Future Internet Design (FIND) project. It will be extended to provide the tools for the experimenter to enable cross-layer experimentation. New SILO services will be developed to interface with the IMF and to introduce optical substrate measurement capability into custom protocol stacks.

Both the IMF and SILO will be integrated with ORCA, so that they can be assigned to the slice of a researcher, who can then configure and run them to conduct an experiment. This project will collaborate with the ORCA Augmentation project on an ontology for measurement capabilities.

This project will collaborate with other GENI projects on the development of a common GENI instrumentation and measurement architecture.

Current Capabilities

The overall architecture of the project has been articulated. The first diagram below shows the experimenter view of the proposed system; realization of this is part of our Year 2 goals. The second diagram below shows the component systems interaction architecture.

Experiment View (Feb 2010)

Architecture (as of July 2010)

At the end of Spiral 2, we are ahead of our goals with respect to the main vision of the project, and have demonstrated real-time reactive use of optical substrate measurements to allow in-slice protocols to react by tuning optical substrate parameters. A detailed description is available in the GEC8 demo report. The diagram below shows the essentials of the demo setup.

The IMF project uses the BEN facility for its physical realization. See the ORCA/BEN project .
