This system protects against policy violations that are not detected by traditional systems without requiring alterations to the source and destination applications or the network traffic between them.

Abstract: A novel method that uses the source port field in the transport or connection layer (L4) header to encode control plane information is provided. Specifically, the method encodes control plane information in UDP or TCP source port field of data plane tunnels in an overlay network such as VXLAN.

This semantically richer information is used to allow receivers of proxied traffic to learn the address of the original sender. The semantically richer information can also be used to enable ECMP for the transmitted packets.

Abstract: A local device, such as a field-programmable gate array, has a local state machine and a local interface component for communicating with a remote device that implements a remote state machine. The local interface component receives a new set of incoming data from the remote device and determines whether the new set is good data or bad data. If good data, then the local interface component causes the new set of data to transmitted internally for use by the local state machine. If bad data, then the local interface component does not forward the new set of data to the local state machine, which instead continues to use a previously received set of good data. Although the clock rate of the local and remote state machines may differ from the frame rate of the local interface component, their operations are nevertheless synchronized.
