A method for monitoring and optimizing interlayer network performance including generating network performance information data indicative of network transmission characteristics from one of a data link layer device, physical layer device, network layer device, transport layer device, session layer device, presentation layer device, and application layer device; including the network performance information data in a data packet; communicating the network performance information data in the data packet from one of the data link layer device, physical layer device, network layer device, transport layer device, session layer device, presentation layer device, and application layer device to a data link layer device; and in response to receiving the network performance information data, optimizing network performance by performing a function by the data link layer device. A system for monitoring and optimizing interlayer network performance is also included.
