The scope of work on this project is to develop a prototype mechanism that allows researchers or enterprise network managers to direct campus/enterprise traffic to/from the public Internet through GENI infrastructure in a way that meets opt-in requirements for GENI.

Priority activities that contribute to this scope include the following items:

1) Produce an opt-in requirements document covering this mechanism for the GENI Spiral 1 prototype environment.

2) Produce a reference design showing how a planned Spiral 1 project(s) opt-in can be implemented with Spiral 1 end-to-end connections.

3) Demonstrate how GENI could use this local opt-in mechanism to manage test and background traffic loads at GENI scales.

Project Technical Documents

Opt-In Requirements doc This document outlines requirements for a strong wholesale opt-in mechanism for GENI. When fully deployed it would permit GENI experimenters to request that ISPs redirect traffic from a huge population of innocent users through GENI infrastructure. These users are innocent in the sense that they do not have to do anything at all to participate, and might not even be aware that they are doing so. Key to wholesale opt-in is that it fully engages the Institutional Review Board (IRB) process and that all participants are motivated by their own self interests to do the right thing.

Spiral 1 Connectivity

Initial local deployment for this project is planned at 3ROX. External addresses are TBD. This project might want to use GENI address space if it becomes available, or some other unused address space that is disjoint from current production announcements, or can otherwise tolerate potential GENI churn. IP connectivity between the Regional Opt-In prototype infrastructure and the clearinghouse that this project eventually selects will be required. ProtoGENI is a likely clearinghouse partner.

There are no special Layer 2 virtual Ethernet requirements for this project.

This project and CmuLab share some infrastructure, since they will both involve CMU students and networks.
