Tools to support the evaluation of distributed documents

This part of the project is focusing on developing software tools to assist in the process of evaluating distributed documents. While the collection of tools continues to grow, the cornerstone of this part of the project remains a set of tools called WANDS. WANDS stands for Wide-Area Network Delay Simulator.

The WANDS tools allow document designers to view their documents locally while experiencing realistic network delays similar to those their users may experience if they are across the hall, across the country, or across an ocean. The WANDS tools work by collecting statistics about real network delays, processing the data, and using the results to drive an instrumented WWW server.

Using these tools, designers can:

This is only a partial list of the questions that can be answered. As more tools are developed, more questions can be addressed.
