Ariba: Seamless Connectivity that "Just Works"

Ariba provides what services and applications seek: seamless connectivity that "just works". Providing this connectivity introduces increasing challenges, e.g., wireless network access, mobility, heterogenity, and, middle-boxes (e.g., firewalls, or NAT gateways) impede end-to-end communication and, therefore, the development of new services and applications. Each of those challenges has its tailored solution. However, most of the solutions need dedicated support by the infrastructure, require manual configuration and do not adapt to changing network conditions. Furthermore, they often do not run across heterogeneous networks (e.g., pure IPv4, IPv6, or different networks behind NAT-gateways).

To ease development of services and applications, and, to deploy them spontaneously, we developed the ariba framework which is part of the spontaneous virtual networks (SpoVNet) project. Ariba provides service and application developers, a simple, yet extensive, interface which addresses the challenges described above. To this end, ariba itself uses Peer-to-Peer (P2P) techniques, to be independent of dedicated infrastructure. Therefore, it uses the resources of the end-systems only. Ariba deploys an P2P overlay network for each application. Self-organization of this overlay minimizes configuration overhead. Furthermore, the structure of the overlay adapts to changing conditions in the underlying network. Thus, applications do not need dedicated mechanisms to handle communication interruptions, or mobility, for example. To operate upon different networks ariba uses other participants as "relay" to provide connectivity between all end-systems.

Ariba is developed by the ​Institute of Telematics (research group of Prof. Zitterbart), ​Karlsruhe Institute of Technology (KIT) as part of the ​SpoVNet project. The ​Baden-Württemberg Stiftung kindly funds this project within the Förderprogramm Informationstechnik Baden-Württemberg (BW-FIT) program.

Ariba is under active development and open to contributions.

Ariba + MCPO + VLC = overlay based scalable video streaming We have published our Ariba/MCPO based VLC streaming plugin. VLC is the well-known multimedia player for video and audio. It comes with a number of streaming modules, but none that supports overlay-based application layer multicast streaming. The Ariba/MCPO streaming plugin called AribaMC provides scalable overlay-based application layer multicast streaming with all features that Ariba gives you: handling of NAT, mixed IPv4/IPv6 support, Bluetooth support, mobility handling, automatic bootstrapping ...

• Ariba was 2nd best demo at ACM SIGCOMM'09

The Ariba Group attended this year's ACM SIGCOMM 2009 in Barcelona to present the demo "Reconnecting the Internet with ariba: Self-Organizing Provisioning of End-to-End Connectivity in Heterogeneous Networks". The demonstration covered a scenario in which several heterogeneous protocols and devices were connected in face of network changes and reconfigurations. There was a huge interest in the topic and fruitful discussions.
The demo was awarded a Honorable Mention by the committee and therewith made it 2nd best demonstration out of 25.
