Abstract: A methodology for operating an authoritative DNS server includes receiving a DNS query from a DNS client, in response to the DNS query, traversing a label tree stored in the authoritative DNS server to find a resource record that matches the DNS query, while traversing the label tree, encountering a LINK record in the label tree that is configured to redirect the traversing to a different branch of the label tree, and in response to the LINK record, redirecting the traversing to the different branch of the label tree, wherein the LINK record is a resource record type that is hidden from DNS clients and is configured to redirect for an owner of the record type and subordinates thereof.

Abstract: A method and system are provided for transmitting information in a Mobile Internet Protocol (IP) environment, which includes a home agent (HA) provided at a home network, a base station (BS) broadcasting a pilot signal, a foreign agent (FA) provided at or associated with the BS, a mobile node (MN) providing the ability to detect and identify itself to a BS, a proxy mobile node (PMN) Identifying the MN wherein the PMN is provided at the BS. If the PMN identifies the MN, the PMN retrieves an IP address for each of the MN, FA and HA and sends a registration request to the FA. The FA relays the registration request to the HA, and the proxy MN is registered with the HA. Thus, the MN functionality is provided transparently to the MN by the PMN. This significantly simplifies the configuration of the MN and the Mobile IP network.

Abstract: A method and system is provided for transmitting information from a mobile computer to a server utilizing point-to-point protocol (PPP). The system enables a PPP session to be maintained between a mobile user device and a PPP termination device. A Mobile IP address is assigned to customer premise equipment (CPE) associated with the user device, e.g., a PC. The CPE includes a Mobile IP Mobile Node and L2TP access concentrator (LAC). The Mobile IP address is registered with a Home Agent. The PC initiates a PPP session to the LAC, which initiates an L2TP session to an L2TP Network Server (LNS) via a tunnel between the Home Agent and the a Foreign Agent. The Mobile IP Mobile Node registers with the Home Agent each time it detects a new base station. Thus, the Home Agent is informed of the new location to forward IP packets for the mobile computer.

Abstract: The present invention is directed to a unique method of retailing electronic multimedia in a controlled environment, and to a system which enables such a retailing method. Such an environment is generated by requiring the creation of portable and/or hard copies of such multimedia files to be generated only in specific retail locations. Such retail locations would physically contain no pre-recorded media files. Rather, they would comprise one or more local servers located in the retail locations and connected via a network to one or more remote sources. Such remote sources may comprise servers, libraries, databases, and the like. While no pre-recorded electronic media is stored on the local server, it can be downloaded and held in a cache on the local server. From the local server, the media can be saved onto a portable storage medium. Eliminating local storage of the electronic media files increases control over their distribution and maximizes distribution efficiency.
