Abstract

We consider the problem of content-based routing and dissemination of highly-distributed, fast data streams from multiple sources to multiple receivers. Our target application domain includes real-time, stream-based monitoring applications and large-scale event dissemination. We introduce SemCast, a new semantic multicast approach that, unlike previous approaches, eliminates the need for content-based forwarding at interior brokers and facilitates fine-grained control over the construction of dissemination overlays. We present the initial design of SemCast and provide an outline of the architectural and algorithmic challenges as well as our initial solutions. Preliminary experimental results show that SemCast can significantly reduce overall bandwidth requirements compared to traditional event-dissemination approaches.
基于内容的流传播的语义组播
我们考虑了基于内容的路由和从多个源到多个接收者的高度分布式、快速数据流的传播问题。我们的目标应用领域包括实时、基于流的监控应用和大规模事件传播。我们介绍了SemCast,这是一种新的语义多播方法,与以前的方法不同,它消除了在内部代理中基于内容的转发的需要,并促进了对传播覆盖结构的细粒度控制。我们介绍了SemCast的初始设计,并概述了架构和算法挑战以及我们的初始解决方案。初步实验结果表明,与传统的事件传播方法相比,SemCast可以显著降低总体带宽需求。
