One of the major reasons that hinder ISPs to provide DiffServ is that the service level cannot be guaranteed when a specific traffic flow traverses a number of DS and non-DS domains. The issue of the impact of non-DS domains or non-DS routers in a hybrid multi-domain DiffServ network on the performance of Premium Services and Assured Services has been largely ignored by the research community. In this paper, we first present a preliminary queueing analysis of the hybrid multidomain DiffServ network based on a tandem queue model. Then we propose a performance metric called SPI (Service Provision Index) to measure the service level degradation of preferred services in a hybrid multi-domain DiffServ network with respect to an All-DS network. Network simulations and emulations are conducted on a variety of scenarios with different parameter settings to explore the performance of a hybrid multi-domain DiffServ network. Based on the quantitative analysis, the simulation and emulation results, we make some observations on the underlying problem, which could help ISPs or researchers determine the major factors of service degradation, as well as possible directions to improve the services.","PeriodicalId":302787,"journal":{"name":"Proceedings.

In addition to bandwidth limits, the delays have an apparent \"random\" component due to the complicated dynamics of the network traffic. We consider that the messages sent over the network are subjected to three types of delays: (a) propagation delays along the links, (b) delays due to bandwidth availability on the links, and (c) \"other delays\" at the intermediate nodes which are randomly distributed according to unknown distributions. We propose an overlay network of in-situ instruments on such a network to collect delay measurements, and to compute and implement paths for message transport. We propose an algorithm to compute a path whose message delay is close to the optimal expected delay with a high probability, based entirely on measurements. We then present a multiple path method for achieving low end-to-end delays, which is implemented over the Internet using user-level daemons. These daemons realize multiple paths among themselves without explicit support from the underlying network routers, and achieve higher aggregated bandwidths compared to the usual transport methods.","PeriodicalId":302787,"journal":{"name":"Proceedings.

Support for multicasting is an important requirement in collaborative applications and several multicast frameworks supporting different ordering semantics such as FIFO, causal and total ordering have been studied. In this paper, we study the ordering requirements imposed by the modular, compositional structure of a protocol on the underlying multicast communication service (MCS). Collaborative protocols often consist of multiple functions, and techniques for designing multifunction protocols can be used for their development. The modular structure of such multifunction protocols may impose certain ordering requirements on the underlying MCS. We propose a scheme that allows a protocol to specify its ordering requirements and a technique to implement these requirements using an underlying MCS. We show that protocol design and composition is simplified if the messages are delivered in the application-specified order. We also show that the underlying MCS can exploit the structured communication pattern imposed by the modular structure of a protocol to improve the performance.","PeriodicalId":302787,"journal":{"name":"Proceedings.

The traditional hierarchical view of data, information and knowledge as various stages of (artificial) intelligence sidesteps a significant stage, namely \"experience\", which is the main concern of artists. With digital multimedia taking a more prominent role in arts and entertainment, we have much more opportunity to create unique experiences, as well as new challenges to overcome. Of particular interest are those experiences which provide the observer the opportunity to participate in and respond to events. Immersive virtual reality experiments aspire to achieve this, but generally for one specific user. Should we generalize this concept to performances involving multiple artists and multiple audiences, we will then have a distributed media system for performing arts. At the heart of this idea are several questions, such as how digital presentations may affect experiences, or how information may be presented to create a specific experience. From a technology standpoint, a number of research and development issues must be overcome. These provide the means for data to be accurately collected, measured, tested, proven, and delivered, in conjunction with artistic, contextual, and user specific concepts. Progress in this area has been made at a new laboratory for distributed media and the arts.","PeriodicalId":302787,"journal":{"name":"Proceedings.
