Scope

This project will add capabilities to the VINI testbed to enable experiments to carry traffic from real users; and increase the experimental use of the VINI testbed by providing familiar experiment management functions. The deliverables for this project all comprise software for supporting external connectivity and flexible, facile experimentation on the GENI testbed. The primary deliverables are a BGP session multiplexer – a software router based on the Quagga software routing suite, software support for virtual tunnel and node creation, and integration of the above functionality with clearinghouse services developed as part of the ProtoGENI project.

In particular, this project contributes to GENI design and prototyping through BGP mux development integration with ISPs; tunnel & topology establishment & management; ProtoGENI clearinghouse integration; and support for isolation & resource swapout.

Spiral 1 Connectivity

The DTunnel system is installed in the ​VINI testbed at Georgia Tech using addresses from their IP address space. The BGPMux part of this project will eventually require external connections and addresses that are not part of VINI address space. Actual addresses for this phase are TBD. Details of IP connectivity with PSGnet for the BGPMux part of this project is TBD. Layer2 virtual ethernet connectivity is not required for this project.
