ABSTRACT:
Example methods and apparatus to deploy and monitor network layer functionalities are disclosed. A disclosed example method includes receiving an Internet Protocol (IP) packet at an input of a server, the IP packet being received from a communicatively coupled router, identifying the IP packet as a production IP packet or a non-production IP packets, when the IP packet is the non-production IP packet, manipulating data within the IP packet to monitor network layer functionality, forwarding the manipulated non-production IP packet to the router, and when the IP packet is the production IP packet, forwarding the production IP packet to the router without manipulating data within the IP packet.
