A method and apparatus for maintaining a communication link through a NAT or other boundary device. Keep-alive messages (keep-alives) are transmitted and received by the boundary device to maintain the link therethrough. Address information of a keep-alive purports that keep-alive has traversed or is to traverse a predetermined portion of the communication link, such as a wireless 'over the air' portion. However, the keep-alive is inhibited from traversing the predetermined portion. This may be accomplished by one or more of: spoofing the origin of the keep-alive such that it only appears to have traversed the predetermined portion; and causing the keep-alive to be discarded before traversal of the predetermined portion. Discard may be facilitated by configuration of the TTL field of the keep-alive or by use of a filtering device.

Method and apparatus for management of network communications

The present invention provides for method, system, and apparatus for facilitating communication between a first set of networked devices, such as client devices, and a second networked device, such as a server. A query message is transmitted from a representative device of the first set of networked devices, to the second networked device. The representative device may be selected in several ways. A response message may be transmitted from the second networked device, the message comprising an indication of devices from the first set of networked devices for which communications are pending. The response message is processed and devices identified in the response message are notified.

Method and system for aggregating communications

Systems and methods are described for establishing credentials at a device and at a device management server for the purpose of exchanging secure credentials in order to mutually authenticate the device and the server. A credential generation algorithm is described which uses a plurality of seeds, including the hardware identity of the device, the server identity, and a shared private key, to generate two sets of credentials, one to be used by the device and the other to be used by the device management server. The credentials are exchanged between the device and the server during any session, thereby assuring mutual authentication.
