S3MONITOR Project Status Report

Period: Fourth quarter 2009

Title: Scalable, Extensible, and Safe Monitoring of GENI Clusters

Authors: Sonia Fahmy, Purdue University
Puneet Sharma, HP Labs

Major accomplishments

Milestones achieved

The Purdue contract with BBN was finalized on November 30th, 2009, and the first milestones and deliverables stated in the contract are scheduled for January 2010.

We are currently developing the system design document, and investigating how to port the Scalable Sensing Service onto the ProtoGENI platform.

Deliverables made

During the sixth GENI Engineering Conference, held in Salt Lake City, Utah, Sonia Fahmy gave three presentations about the project:

ProtoGENI cluster meeting

Experiment Workflow and Services working group

Measurements working group

Description of work performed during last quarter

Activities and findings

We are currently investigating the porting of sensor pods onto the ProtoGENI platform. A sensor pod is a web-service enabled collection of lightweight measurement and monitoring sensors that collect information at a machine. This information spans both network properties such as network connectivity, latency to some other machine in the system, bandwidth to another machine, and machine attributes. These sensors gather information actively (e.g., send some packets on a network link to detect available bandwidth) or passively.

The project PIs Sonia Fahmy and Puneet Sharma held telephone calls to discuss how to extend sensor pods and port them to ProtoGENI. The PIs also held a conference call with Robert Ricci to discuss challenges with integration with ProtoGENI.

Project participants

Sonia Fahmy, Purdue University Puneet Sharma, HP Labs

A graduate student at Purdue University will join the project in January 2010.

While the subcontract with HP is still being negotiated, Puneet Sharma has started reviewing resumes for an additional participant in the project, with an anticipated start date in early January 2010. This participant will help port the scalable sensing service measurement pod to ProtoGENI.

Publications (individual and organizational)

The following publication which is under revision is related to this project:

On the Cost of Network Inference Mechanisms, by Ethan Blanton, Sonia Fahmy, Greg N. Frederickson, Sriharsha Gangam, under revision for publication in IEEE Transactions on Parallel and Distributed Systems.

The following publication from HP is under submission for review:

On Correlations between Capacity and Available Bandwidth.

Outreach activities

Sonia Fahmy discussed the project with participants attending the IEEE International Conference on Network Protocols (ICNP) 2009, and the Computer Communication Workshop (CCW) 2009, both held in October 2009.

Sonia Fahmy also served on the technical program committees (TPCs) of SIGMETRICS 2010 and INFOCOM 2010, and reviewed several measurement and testbed-related papers.

Puneet Sharma served on the TPC of COMSNETS 2010 and reviewed several measurement architecture-related papers.


During the sixth GENI Engineering Conference, held in Salt Lake City, Utah, we discussed the project with other measurement projects that started in spiral 2 and those that had started in spiral 1. We discussed common aspects with the teams from University of Kentucky, University of Wisconsin, and the Ohio State University. We also discussed the project with additional ProtoGENI teams, including the team from University of Washington.
