PEERING is an environment where researchers and educators can play with BGP announcements in a real but sandboxed environment.
Description from the website:
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:
- PEERING for researchers. Today, it is hard for researchers to conduct Internet routing experiments. To perform a routing experiment, a research institution has to obtain Internet resources (IP addresses and ASNs) and establish relations with upstream networks. PEERING eliminates these obstacles and provides researchers controlled on-demand access to the routing ecosystem.
- PEERING for educators. Educators can use the PEERING infrastructure in teaching students the Internet routing architecture. The students access to live BGP sessions to multiple ISPs.
