A recently granted patent (Publication Number: US11909609B1) discloses a method implemented by a network traffic management system involving network traffic apparatuses, client devices, or server devices. The method includes generating a cloned network packet with the same header and payload as a received network packet, along with creating metadata containing state information for the received packet. This metadata, which includes data related to the session history of the packet, is inserted into the cloned network packet. The received network packet is then sent to a destination device without the metadata, and a network diagnostic operation is performed solely on the cloned packet. Additional steps involve creating an extra network packet for the received one, inserting metadata, and conducting the diagnostic operation on the cloned packet.

Furthermore, the patent describes a non-transitory computer-readable medium storing instructions for inserting metadata into a data stream, which involves generating a cloned network packet, creating metadata with state information, and sending the received packet to a destination device without the metadata. The network diagnostic operation is carried out only on the cloned packet. The patent also covers a network traffic manager apparatus and system, detailing similar processes of generating cloned packets, inserting metadata, and performing diagnostic operations. These inventions aim to enhance network traffic management efficiency by selectively analyzing cloned packets, thereby optimizing network diagnostic procedures and improving overall network performance.
