Network Protocols for Applications of Shared Virtual Reality

Abstract

Files are usually used for exchange of 3D data between graphical applications, but this approach is not feasible for applications of shared virtual reality. Thus a network protocol is used for this purpose. Two antithetical requirements are claimed for such protocol. Protocol has to be partially or completely reliable. Neither delay jitter nor too high delay are acceptable. This paper explains and analyzes new version of protocol called Verse. This improves shortcomings found in UDP, TCP, SCTP and DCCP transport protocols. The Verse protocol was designed for sharing 3D data between applications of shared virtual reality. This paper also contains results of experiments comparing suitability of network protocols for application of shared virtual reality.
