Quality-adaptice methods dor elastic real time applications

这项工作的广泛目标是开发新的系统和网络技术，以支持时间敏感的分布式应用程序，使用尽力而为的商品基础设施。这项工作的研究目标是相关的质量适应的一般主题，其动机是解决时间敏感的应用程序和最大努力的服务模式，仍然是唯一的选择提供给绝大多数互联网用户之间的冲突。我们还旨在探讨如何应用上下文感知计算的原则，以提高面向用户和社区的视频制作和分发的过程。

The broad goal of this work is to develop new systems and networking techniques to support time-sensitive distributed applications, using a best-effort commodity infrastructure. The research objectives of this work are related by a general theme of quality adaptation, the motivation of which is to address the conflict between time-sensitive applications and the best effort service model that still remains the sole option available to the vast majority of Internet users. We also aim to explore how to apply principles of context-aware computing to enhance the process of user and community oriented video production and distribution.
