Experimental Study of Symmetric Computer Model of Http-Filter

Filtering of users' requests to Internet resources allows to regulate an access to them. The paper presents a symmetric computer model of filtering device for HTTP-requests at the packet level using filtration method on the basis of URL address. The device is equipped by two symmetric connection points and is mounted into the gap of the connection between the Web-client network and Web-server. Proposed model contains two equivalent channels that provide passing of packet traffic through the device and its filtering. We propose the technique of test bench studying of HTTP-filter characteristics based on simulation of filtering process for a Web-system. The technique was applied to the proposed model. The results of experimental testing are presented.
