Abstract: Methods, non-transitory computer readable media, network traffic manager apparatuses, and systems includes receiving a plurality of network packets. Metadata comprising state information for the received plurality of network packets is generated. The generated metadata is inserted into the received plurality of network packets or a cloned version of the plurality of network packets. A network diagnostic operation is performed on the received plurality of network packets based on the inserted metadata into the received plurality of network packets or the cloned version of the plurality of network packets.

Abstract: Methods, non-transitory computer readable media, network traffic manager apparatuses, and systems that assist with mitigating DDoS attack using a hardware device includes determining when a received network packet in an established connection between a client and a destination server includes a connection identifier cookie. A connection validation cookie is generated based on at least data in the received network packet, when the determination indicates the received network packet includes the connection identifier cookie. The connection identifier cookie is compared against the generated connection validation cookie. The received network packet is dropped when the comparison indicates the connection validation cookie fails to match the connection identifier cookie.
