Abstract:
1. An Internet communication infrastructure comprising: a first end point device having a unique identifier; a second end point device that using the unique identifier packetizes target data into a plurality of packets, the target data having at least one target bit sequence, and the packetization of the target data comprising segmentation of the target data; a service module that receives at least an indication that an attempt to exchange the target data is underway; a switching device comprising processing circuitry, storage, a first port that participates in a first pathway to the first end point device, and a second port that participates in a pathway from the second end point device; the storage containing both a first template corresponding to a first portion of the at least one target bit sequence, and a second template corresponding to a second portion of the at least one target bit sequence, the first template and the second template being spatially related to compensate for the segmentation of the packetized target data; the processing circuitry receives at least one of the plurality of packets via the second port and performs a first comparison followed by a second comparison if the first comparison fails, the first comparison comprising an attempt to match the at least one of the plurality of packets with the first template, and the second comparison comprising an attempt to match the at least one of the plurality of packets with the second template; and the processing circuitry, upon a successful first comparison or a successful second comparison, delivers to the service module the at least the indication that the attempt to exchange the target data is underway.
