About VINI
What is VINI?
VINI is a virtual network infrastructure that allows network researchers to evaluate their protocols and services in the wide area. VINI allows researchers to deploy and evaluate their ideas with real routing software, traffic loads, and network events. To provide researchers flexibility in designing their experiments, VINI supports simultaneous experiments with arbitrary network topologies on a shared physical infrastructure.
VINI is related to the PlanetLab project. The VINI effort has produced three main artifacts:
A testbed that is distinct from the public PlanetLab. VINI is an instance of a "private PlanetLab" that uses MyPLC to manage the nodes. The VINI nodes offer more bandwidth (1Gbps) than most public PlanetLab nodes.
A set of extensions to the PlanetLab kernel and tools called Trellis. Trellis integrates virtual network topologies and slices. Note that currently Trellis only runs on the VINI infrastructure mentioned above, not on PlanetLab.
The initial proof-of-concept toolkit, described in our SIGCOMM'06 paper, called PL-VINI. This toolkit leverages Click, User-Mode Linux, XORP, and Quagga to build routing overlays inside slices on the public PlanetLab. This prototype is no longer being actively developed, but it still works on PlanetLab.
Who can use VINI?
All PlanetLab users can now access the VINI testbed, and create virtual networks within their slices, via the SFA federation interface. For more information, see the SFA User Guide.
What's the current status?
The VINI testbed currently consists of 42 nodes at 26 sites connected to the National LambdaRail, Internet2, and CESNET (Czech Republic). The Trellis software runs on all VINI nodes.
