The program is intended to work between a caching proxy-server and computers of the LAN, effectively regulating a degree of congestion of the channel of connection with the global network over the HTTP-protocol.

The current version of the program (1.6.3) carries out the following functions:

• Automatically limits speed of the data downloading to IP-address up to the specified value.
• Limits size per week of data which are downloaded to IP-address.
• Limits the number of simultaneous connections from the browsers and other HTTP-using programs that users use for surfing in the Internet
• Logs the all HTTP-requests in the file in the Apache-like format
• With the help of a special client-side program "BSB Client Informer" the users can receive the information about their size of data downloaded for current week, current restriction of speed and etc.
