Abstract
The present disclosure is directed to a system and method for applying unique routing rules to encrypted data packets being transmitted via a tunneling protocol. Because encrypted data packets are unintelligible at intermediary points along a secured link or “tunnel,” a multi-path router located between the tunnel endpoints is typically unable to apply unique routing rules. To enable unique routing, the disclosed method relies on a unique identifier that is associated with the secured link established between an initiator and a receiver (i.e., the tunnel endpoints). The unique identifier is transmitted with one or more encrypted data packets and is used at intermediary points to differentiate the encrypted data packets so that unique routing rules can be applied.
