A method and computing device configured to send and receive traffic over a virtual private network (VPN) connection, the computing device having a processor; and a communications subsystem, where the method determines that a first trigger had been met, wherein the first trigger is dynamically configured based on at least one factor at the computing device; monitors whether data traffic exists over the VPN connection for a first time period; and if no data traffic exists over the VPN connection for the first time period, disconnects the VPN connection.

Method and system for managing a VPN connection

In some implementations, a method for routing communication includes determining a binding interface for a communication session based on a forwarding information base (FIB) and a destination for the communication session. The communication session is from an application running on user equipment (UE), and the binding interface is included in a virtual private network (VPN) tunnel established through an Internet Protocol (IP) security (IPsec) interface. Whether to filter the communication session is determined based on which perimeter of the UE includes the binding interface and which perimeter of the UE includes the IPsec interface.

Filtering network packets in multiple forwarding information base systems

A wireless network and associated method for providing continuous communication service for a mobile unit as it roams within a virtual wireless network. The virtual network includes home and foreign access controllers and a virtual network manager (VN manager). The VN manager is used to maintain a VN configuration record that includes all active access controllers within virtual network and to disseminate said VN configuration record to all active access controllers. A tunneling data communication connection is established between all active access controllers including home and foreign access controllers. When a mobile unit first connects to home access controller and then roams to foreign access controller, communication data is transmitted between the mobile unit and the foreign access controller to provide continuous data communication on the basis of the characteristics defined by the virtual networking services while simultaneously preserving the IP configuration of mobile unit on the network.
