Abstract:
A method for monitoring information traffic through a traffic link transmitting first and second differing information signals each having a plurality of information layers and first and second pluralities of information packets in a monitoring system having monitoring circuitry and including processor circuitry and a server operating cooperatively with said monitoring circuitry, said method comprising the steps of:segmenting said information packets of said first and second pluralities of information packets into information cells to provide corresponding first and second pluralities of information cells; interspersing said information cells of said first and second pluralities of information cells with each other to provide interspersed first and second information cells; intercepting a portion of said interspersed first and second information cells to provide intercepted interspersed information cells using an interceptor coupled to said traffic link; stripping an information layer from said intercepted interspersed information cells by said monitoring circuitry to provide a remaining information signal including portions of said intercepted interspersed information cells; reassembling said intercepted interspersed information packets of at least one of said first and second pluralities of information packets within said remaining information signal to provide a plurality of reassembled information packets by said processor circuitry; and performing an analysis on said plurality of reassembled information packets by said server.
