Attenuate is an 'add-on' for Microsoft's Internet Information Server (IIS). Attenuate facilitates the imposition of a variety of bandwidth constraints (throttling) without rejection of service. These include:

• Total server download rate.
• Total server upload rate (asp).
• Individual (connection) upload rate.
• Rule based assignment of download rate constraints. Rules are specified as wild-card strings. Constraints can be specified as both/either connection or total.

Attenuate II - V2.5 and V3.0 are here!

Examples of use include limiting download rates of .zip and .exe files on a per directory basis, limiting .jpeg and .gif download rates sitewide, and preserving bandwidth where streaming media is used. These techniques permit valuable server capacity to be stretched.

Request based constraint imposition provides a great deal of flexibility. Attenuate examines each server request, as typed into the browser, and assigns download rate constraints based on a user specified list of wild-card strings. Attenuate successively compares each request to these list entries and assigns constraints based on the result of any match.

Attenuate dramatically increases the number of options available for controlling a web site. Any file, or group of files, can be limited to preserve bandwidth for other purposes. With Attenuate you can, for instance, limit download rates of all zip files in all logical sites/directories to levels guaranteed to preserve bandwidth for other users.

A few power users, downloading gif and jpg files, can seriously impede the performance of the server for other users. New, with the introduction of Attenuate II, is the convenience of remote administration. A single Attenuate client can administer any number of Attenuate installations on the TCP-IP network

Attenuate III is now available. The totally new architecture provides for lower overhead and more robust performance in high load application. An Attenuate product key will work for either Attenuate II or Attenuate III.
