Abstract

A method is taught 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 the monitor circuitry. The method includes segmenting the information packets of the first and second pluralities of information packets into information cells to provide corresponding first and second pluralities of information cells and interspersing the information cells of the first and second pluralities of information cells with each other to provide interspersed first and second information cells. Intercepting a portion of the interspersed first and second information cells to provide intercepted interspersed information cells using an interceptor coupled to the traffic link and stripping an information layer from the intercepted interspersed information cells by the monitoring circuitry to provide a remaining information signal including portions of the intercepted interspersed information cells are also set forth. The intercepted interspersed information packets of at least one of the first and second pluralities of information packets within the remaining information signal are reassembled to provide a plurality of reassembled information packets by the processor circuitry. An analysis is performed on the plurality of reassembled information packets by the server.
