Due to the lack of deployment of a network-layer multi-cast service, many overlay multicast protocols have been designed and deployed across the Internet to support content distribution. To our knowledge, however, none have provided a rigorous analysis of the problem or the effectiveness of their proposed solutions. Here, we set aside the engineering(More)
Many overlay multicast protocols have been designed and deployed across the Internet to support content distribution. To our knowledge, however, none have provided a rigorous analysis of the problem or the effectiveness of their proposed solutions. We define the <i>Overlay Network Content Distribution</i> (OCD) problem to allow such analyses.
conference reports straints, energy concerns, flexibility for application to choose policies, and the noninteractive nature of applications, which makes it different from traditional mobile systems. Q: The first generation of sensor systems are not powerful, but with powerful future sensor systems will the abstractions change? A: Some of the constraints and(More)
