Description

The invention relates to the field of telecommunications and can be used to implement user search information requests and operational identification of information in packet-switched data networks, as well as in distributed information and reference (search) systems and in storage systems for electronic educational resources, on information resources of electronic libraries, data processing centers and cloud services. A device known from Russian Patent No. 2115952, "Information Retrieval Device," IPC G06F 17/40, published July 20, 1998, includes boundary registers, summing and subtracting counters, comparison circuits, memory units, and computing units. This analog, when receiving a digital message and searching for a specific digital sequence, allows for determining the parameters and compliance of the transmission sequence with the data exchange rules established for a given protocol. The disadvantages of this device are the relatively long time required to identify packets (since identification is performed by sequentially analyzing feature values) and its narrow scope of application—it's limited to analyzing the TFTP protocol to ensure the observed packet sequence complies with the rules established for that protocol. All of this limits the use of this analog device for protocol analysis in modern high-speed computing networks. A device known from Russian Patent No. 2313128, "Information Retrieval Device," IPC G06F 9/46, published December 20, 2007, Bulletin No. 35, is described.
