Automatic network optimization
Systems and methods for automatic network optimization are provided. One embodiment comprises receiving a first data packet including an unenhanced payload from a first network device. A portion of the first data packet is then modified, the portion being outside the unenhanced payload of the first data packet, to indicate that a first optimization device is capable of enhanced communication. Next, the modified first data packet is sent from the first optimization device to an endpoint device. An indication of a capability of enhanced payload processing may be received. Based on the indication, an enhanced payload of a second data packet addressed to the endpoint device based on the indication may be generated. Finally, the second data packet including the enhanced payload may be sent to the endpoint device.
