Method and system for routing traffic across multiple interfaces via VPN traffic selectors and local policies

摘要

Method and system for routing traffic across multiple network interfaces with use of VPN traffic selector as part of decision making, for example, in the context of a mobile communication network. A packet data unit (PDU) is generated in association with an application that can be selectively activated on a mobile device and carries a destination Internet protocol (IP) address representing a server that supports the application. A broker associated with the mobile device retrieves information relating to traffic selectors and determines whether the PDU is associated with an operator application or a non-operator application based on the destination IP address and the information relating to traffic selectors. The broker routes the PDU to one of the multiple network interfaces based on whether the PDU is from an operator application traffic and local policies. When the PDU is associated with an operator application and the mobile device is not connected to its operator network, the PDU is routed via a virtual private network (VPN) selector.
