Domain name resolution making IP address selections in response to connection status when multiple connections are present

Abstract:
Methods, configured storage media, and systems are provided for resolving domain names into IP addresses in a path-sensitive manner, namely, a manner that may consider information about a link to a server and/or information about routers and other path components. The IP addresses given in response to domain name resolution requests are selected to provide increased reliability and/or dynamic load-balancing over paths.

Selective encryption with parallel networks

Abstract:
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.

Tools and techniques for directing packets over disparate networks

Abstract:
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. It protects the tools and techniques for directing packets over multiple parallel disparate networks, based on address and other criteria. The invention helps companies who are utilizing point-to-point, frame relay or MPLS networks to achieve the highest level of reliability for Wide Area Network (WAN) connectivity by aggregating data lines from private networks with public Internet lines using VPNs and/or other Internet-based networks. The patent protects the methods used to allow frame relay, MPLS and/or point-to-point networks to co-exist with VPN and other Internet-based networks for redundancy and the ability to failover from one disparate network to the other transparently.

Combining routers to increase concurrency and redundancy in external network access

Abstract:
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.

Tools and techniques for directing packets over disparate networks

Abstract:
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.

System and method for transmitting a user's data packets concurrently over different telephone lines between two computer networks

Abstract:
Methods and systems are provided for transmitting a user's data between two computer networks over physically separate telephone line connections which are allocated exclusively to the user. The user's data is placed in data packets, which are multiplexed onto the separate connections and sent concurrently to a de-multiplexer. The data packets contain a computer network address such as an Internet protocol address. A dynamic address and sequence table allows the de-multiplexer operation to restore the original order of the data after receiving the packets. The set of connections constitutes a virtual "fat pipe" connection through which the user's data is transmitted more rapidly. Additional users may be given their own dedicated "FatPipe" connections.
