Abstract:
A method of intelligently sorting packets/datagrams for sending through appropriate branches of a N-way split VPN tunnel according to embodiments of the present invention allow for efficient movement of network traffic to and from a remote network location. Intelligent sorting may be based on a wide range of criteria in order to implement different policies. For example, datagrams may be sorted for sending through the branches of a 3-way split tunnel so that all traffic from a remote network location ultimately destined to servers at a central location may be sent via a secure VPN tunnel, all traffic that matches a “white-list” of trusted external sites may be sent directly to and from these sites to the remote network location, and all other traffic may be redirected through a Web service that scrubs and filters the traffic to/from questionable sites. Furthermore, the VPN tunnel may be chosen to minimize latency, to detour around network failures, or to conserve energy by minimizing the number of routers a datagram passes through.
