Orta — an Overlay for Real Time Applications
01 November 2005 / rat
We present Orta, a new peer-to-peer network overlay protocol intended for use with interactive real-time conferencing applications. The implementation is presented as a reusable software library, that is not tied to any existing application. One application, the UCL Robust-Audio Tool, is modified to use this library rather than IP multicast as a proof-of-concept implementation. We present the protocol design, along with evaluation results describing the performance of the overlay, with focus on its usefulness for real-time applications.
Stephen Strowes — Peer-to-Peer Audio Conferencing
7 June 2005 / rat
Congratulations to Stephen Strowes on submitting his MSci dissertation on Peer-to-Peer Audio Conferencing. This dissertation proposes a new overlay multicast service, Orta, that can be used for real-time group conferencing. As a proof-of-concept, the Robust-Audio Tool has been modified to use Orta in place of IP multicast. Stephen presents implementation details and evaluation results detailing the characteristics of the overlay, with some focus on its usefulness for real-time applications.
