BGC Group has been granted a patent for a network tap system that monitors and replays packets between two networks. The system allows for the duplication of packets from a first network to a second network, even when nodes share identical IP addresses.

Network tap for monitoring and replaying network packets
The patent US12052149B2 describes a network tap apparatus designed to facilitate the monitoring and duplication of network packets between two distinct networks. The apparatus includes multiple network interfaces and at least one processor that receives packets from a source device intended for a destination device within a first network. The processor is responsible for sending the original packet to its destination while simultaneously generating a duplicate packet. This duplicate is forwarded to a corresponding destination device in a second network, which shares the same IP address as the destination device in the first network. The apparatus can be configured as an optical fiber network tap or utilize switched port analyzers (SPAN or RSPAN) for effective packet management.
Additionally, the patent outlines features that enhance synchronization and timestamping between the two networks. The internal clocks of the destination devices in both networks can be synchronized using a time server, which may include a global positioning satellite antenna and a grandmaster precision time protocol clock. The processor can also receive timestamp values from the time server, ensuring that both the original and duplicate packets carry identical timestamp information. The apparatus is capable of storing representations of packets in a database, allowing for efficient transmission of duplicate packets based on stored data. The claims further specify that the duplicate packet can either be an exact replica of the original or differ in its signal representation when communicated to the second network.
