    摘要: Methods, devices, and systems for efficient secure parallel data transmission are disclosed. Data from a local source is divided, with one portion being encrypted and then sent over an open public network, and another portion being sent over a private network without any such supplemental encryption. The portions are thus transmitted at least partially in parallel over networks having different security characteristics, in a manner that helps compensate for the lower security of the open public network without imposing unnecessary encryption overhead on packets being sent over the more secure private network.

    摘要: Tools and techniques are provided to provide Voice-over-IP (VoIP) communications. On receiving a user request to initiate a telephonic connection from a local site, at which the user is using a VoIP telecommunication device which has no link failover functionality, a system establishes over wide area network links at least two tunnels between a controller at the local site and another controller. Then the system transmits VoIP traffic over at least one of the tunnels from the controller at the local site to the other controller. The system also detects failure of the primary tunnel during the call and performs failover by changing a data path during the call to transmit packets over at least one non-failed tunnel.

    摘要: A controller is provided for increasing bandwidth between a local area network (“LAN”) and other networks by using multiple routers on the given LAN. Data packets are multiplexed between the routers using a novel variation on the standard SYN packet synchronization protocol, and other components. On receiving data destined for an external network, the controller or gateway computer will direct the data to the appropriate router. In addition to providing higher speed connections, the invention provides better fault tolerance in the form of redundant connections from the originating LAN to a wide area network such as the Internet.

    摘要: To help maintain secure and convenient connectivity for users when IP addresses change, devices connected between sites by using multiple virtual private network security associations update one another when the security association IP addresses change. The device whose WAN interface IP address changed transmits an address change notification message to the other device over a WAN interface whose IP address did not change. The message indicates which IP address(es) changed and new value(s) to use. The devices can then continue the same secure virtual private network session (from a user point of view above the security association level) by using the new value(s) for the changed IP address(es). Use of the new value for the changed IP address is transparent to (unseen by) VPN applications that are running in the LANs. IPSec sessions and load balancing may be provided.

    摘要: Methods, configured storage media, and systems are provided for communications using two or more disparate networks in parallel to provide load balancing across network connections, greater reliability, and/or increased security. A controller provides access to two or more disparate networks in parallel, through direct or indirect network interfaces. When one attached network fails, the failure is sensed by the controller and traffic is routed through one or more other disparate networks. When all attached disparate networks are operating, one controller preferably balances the load between them.
