Abstract
A system and a method are described that reduce or eliminate inefficiencies caused by double encryption in network tunnel communications. In particular, a set of virtual tunnels may be established that require a lower level of encryption in comparison to a full-encryption tunnel. Upon determining that a session is end-to-end encrypted, the system and method described herein may assign the session to one of the virtual tunnels instead of the full-encryption tunnel. By intelligently assigning sessions to virtual tunnels when encryption has already been applied, double encryption may be avoided, which will improve throughput and decrease processor usage. However, in cases where a session is not end-to-end encrypted, the full-encryption tunnel may be utilized to ensure secure communications are maintained between gateways.
