Virtual reality transfer protocol (VRTP): implementing a monitor application for the Real-time Transport Protocol (RTP) using the Java Media Framework (JMF)

The Real-time Transport Protocol (RTP) supports the transmission of time-based media, such as audio and video, over wide-area networks (WANs), by adding synchronization and quality-of-service (QoS) feedback capabilities to the existing transport protocol. RTP has been widely used in the Multicast Backbone (MBone), a virtual network that has become a shared worldwide medium for Internet multicast communications. This work presents the design patterns, architecture and implementation of an RTP monitor application using the Java Media Framework (JMF), a new Java Application Programming Interface (API) for multimedia support. An RTP monitor is an application that receives packets from all participants in a multicast session in order to estimate the quality of service for distribution monitoring, fault diagnosis and both short and long- term statistics. This new RTP monitor is available as a component of the Virtual Reality Transfer Protocol (vrtp), a protocol being developed to support large- scale virtual environments (LSVEs) over the Internet. Initial test results are satisfactory for audio and video streams, as well as prototype RTP-compliant Distributed Interactive Simulation (DIS) protocol streams. Future work includes automated monitoring across WANs and standardizing structured data formats to comply with Management Information Base (MIB) requirements using Extensible Markup Language (XML) target set definitions.
