Ariba: Seamless Connectivity that "Just Works"

Ariba provides what services, and application seek: seamless connectivity that "just works". Providing this connectivity has increased 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 application. Each challenge has its tailored solutions. However, most of these solutions need support by the infrastructure, require manual configuration and do not adapt to changing 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, and, therefore, shares sharing resources between end-systems. Ariba deploys such an P2P overlay network for each application. Self-organization minimizes the configuration overhead. The structure of the P2P overlay network adapts to changing underlying network conditions. Therefore, applications do not need dedicated mechanisms to handle communication interrupts, or mobility. To operate upon different networks ariba uses other participants as "relay" to provide connectivity between all participants.

Ariba is developed at the ​Institute of Telematics (research group Prof. Zitterbart), Universität Karlsruhe (TH) as part of the ​SpoVNet project funded by the ​Landesstiftung Baden-Württemberg within the Förderprogramm Informationstechnik Baden-Württemberg (BW-FIT) Program. Ariba is actively developed and open to contributions.

  • 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.
