Pluggable transceiver to facilitate network traffic analysis
A pluggable transceiver receives, from a client, a first message that indicates a first source IP address as being an IP address of a client, a first destination IP address as being an IP address of the pluggable transceiver, a first source port as being a port of the client, and a first destination port as being a port of the pluggable transceiver. The pluggable transceiver updates the first message to indicate the first source IP address as being the IP address of the pluggable transceiver, the first destination IP address as being an IP address of a server, and the first destination port as being a port of the server. The pluggable transceiver sends the updated first message to the server.
