Broadcast Objects for Effective Data Dissemination in BADD

摘要

Data dissemination systems are difficult to design properly. Since interest in this topic is relatively new, there is little excerption with methods for making performance decisions. this project has been focused on providing tools for understanding the impact of design decisions in dissemination-based data delivery. We have developed two broad classes of tools. The first is a set of simulation-based tools that allowed us to study fundamental algorithms. We have applied these simulators to the problem of information channelization. We have built a test harness for controlling the deployment of multiple experiments and the collection of results into a convenient graphical form. We see this a major step toward a commander's workbench, a tool to help commanders make resource allocation decisions. The second class of tool is a tool kit that allows us to quickly assemble prototype (perhaps in a local-area network) that mimics the ultimate deployed system. A prototype of this kind can be instrumented and performance measurements can be collected that gives us more realistic insight than a simulator. This approach provides the second line of defense.
