.... A V MPEG Player from the Oregon Graduate Institute [4] The MBone videoconferencing application vic [15] was also ported to TAO s A V Streaming Service [17] Recent work includes a video distribution application, combining the A V Streaming Service with the QuO Quality of Service framework [13]. None of these applications allows a simple adaptation for a performance analysis similar to the tests we present in Section 6. In the field of collaborative virtual reality and distributed simulation, design suggestions for CORBA based frameworks have been made [1, 7, 18] and on going projects ....

....this with the MediaNet LSs only. The priority based frame dropping configuration consists of tagging P, B, and I frames with successively higher priority, and during overload the lowest priority frames are dropped. This approximates some past approaches on intelligent frame dropping [4] [21]. The proactive frame dropping configuration also consists of intelligently dropping video frames during overload. In this case, the LS observes when frames start getting dropped for a particular link, and then adapts by proactively dropping all B frames, and then later all P frames. When ....

.... processing in the network was first inspired by the problems of digital video broadcasting in heterogeneous networks [24] 25] The goal of providing adaptive QoS for streaming data is shared by a number of systems, including Active Networks applications [26] 6] 4] QoS middleware substrates [21], 27] 28] and applicationlayer in network processors [29] 7] 30] Other projects have targeted the dissemination to mobile, wireless workstations, such as Quasar [31] and Odyssey [32] None of these systems focuses on sharing resources among many users with differing adaptation ....

....contract indicates that image receipt is early or late. Video Dissemination in a Simulated UAV Context Under DARPA s Program Composition for Embedded Systems (PCES) program and for the US Navy, we have been developing a simulated Unmanned Air Vehicle (UAV) system. The application, described in [4, 5] concentrates on the delivery of video imagery captured by a UAV to distributed control stations and the delivery of control signals back to the UAV. Figure 10 illustrates the architecture of the demonstration system. It is a three stage pipeline, with multiple UAV sending video (in multiple ....

....costs. For instance, next generation avionics mission computing systems [WSOA] must collaborate with remote command and control systems, provide on demand browsing capabilities for human operators, and respond flexibly to unanticipated situational factors that arise in run time environments [UAV]. Moreover, these systems must perform unobtrusively, shielding human operators from unnecessary details, while simultaneously communicating and responding to mission critical information at an accelerated operational tempo. The characteristics of next generation DRE systems present QoS ....

These versions have been described in earlier papers [ICDCS, UAV]. The current version described in this paper is being provided as an open source release to researchers investigating related issues. The Hiper D 2000 version used TCP and an earlier, less functional MPEG viewer, and illustrated the use of framedropping and migration of the distributor in ....

A particularly essential task is supporting the quality of service (QoS) demands of mission critical DRE systems that possess a mix of hard and soft real time requirements, such as avionics mission computing systems [1] mission critical distributed audio video processing [2] [3], and real time robotic systems [4] B. Key Challenges: Flexibility and QoS Assurance DRE systems have historically been custom developed in an ad hoc and inflexible manner. While many operational systems have been built this way, this development process failed to address the following ....

We distinguish the policy of a scheduling strategy, ....

....level network and operating system enforcement mechanisms necessary to provide the right behavior effectively and efficiently given current system conditions. Although it is possible to satisfy contracts and achieve graceful degradation to a limited degree in a limited range of systems today [Kar01], much R D work remains. The research orientation needed to deliver these goals can be divided into the seven areas described below: 1. Individual QoS Requirements Individual QoS deals with developing the mechanisms relating to the end to end QoS needs from the perspective of a single user or ....
