Packet comparison and output system for electromagnetic signals
A recently granted patent (Publication Number: US11923967B2) discloses a device that includes a processing system with a processor and memory storing executable instructions. The device is designed to receive an electromagnetic signal containing multiple packets, extract and store these packets in memory, convert the signal to an optical signal, split it into two optical signals, and convert them back to electromagnetic signals. The device then compares the copied packets with the converted packets using packet comparators, determining if they are identical and outputting them accordingly. The device is positioned on a communication path between originating and destination equipment, allowing for efficient data transmission and analysis.
Furthermore, the patent describes a non-transitory machine-readable medium with executable instructions that enable the device to perform the operations mentioned above. The medium facilitates the comparison of packets using packet comparators, ensuring accurate data transmission and processing. Additionally, a method outlined in the patent involves receiving an electromagnetic signal, storing and converting packets, and performing comparisons to determine packet identity. The method utilizes packet comparators, bit comparison devices, and digital logic to ensure precise analysis and transmission of data. Overall, the patent highlights a sophisticated system for packet processing and transmission, enhancing communication network efficiency and data security.
