What is PEERING

PEERING is a system that provides safe and easy access for researchers and educators to the Internet's BGP routing system, enabling and inspiring transformational research. The system is in part funded by grants from NSF, Google, and GENI. The project, from Columbia University, University of Southern California and Universidade Federal de Minas Gerais (and, formerly, Princeton University), fosters Internet research and innovation. Traditionally, the barriers to conduct Internet routing experiments hindered progress. Most research on interdomain routing is either based on passive observation of existing routes, which cannot capture how the Internet will respond to changes in protocols or policies, or based on simulations, whose fidelity is restricted by known limitations in our understanding of Internet topology and policy. To move beyond these limited experimental approaches, the PEERING testbed connects (via BGP) with real networks at universities and Internet exchange points around the world. Instead of being observers of the Internet ecosystem, researchers become participants, running experiments that announce/select routes and send/receive traffic directly with these networks. The testbed can multiplex multiple simultaneous research experiments, each of which independently makes routing decisions and sends and receives traffic. Researchers can submit proposals to use PEERING. PEERING has enabled research that appeared at top academic and industrial conferences. Without this testbed, none of this research would have been evaluated on the actual Internet, blunting its impact.

Objectives

The long-term goal of the PEERING system is to enable on-demand, safe, and controlled access to the Internet routing ecosystem for researchers and educators:

Result Publication

The core results of the experiments using PEERING must be published in publicly accessible documents. Detailed data produced by experiments, such as ping and traceroute command outputs, must be shared with researchers in accredited higher education institutions.

Experimentation Practices and Conditions

The Internet routing system supports connectivity for people worldwide. The PEERING testbed ensures that experiments produce no noticeable impact on the Internet. PEERING applies the following rules to all experiments:

Please see guidelines on how to submit an experiment and our complete Acceptable Use Policy.

Technical Coordination

The PEERING testbed is operated by researchers at Columbia University, University of Southern California, and Universidade Federal de Minas Gerais. In a very unlikely event of PEERING sending BGP announcements that are not consistent with the policies described above, please email the team immediately, at noc at peering.ee.columbia.edu.
