Foreign agent

Abstract: Strategic public diplomacy, once commonly called propaganda, has existed since the twelfth century, when Richard I, crusading sovereign of England, plucked the eyes from his prisoners and returned them to his arch-rival Saladin-an unmistakable message intended to mold the image that Richard's foreign enemies had of him. Although their methods have grown more sophisticated and gentrified since the Middle Ages, the goal of governments employing strategic public diplomacy has remained essentially the same: to influence public or elite opinion in a foreign country for the purpose of turning the foreign policy of the target country to advantage. The first systematic analysis of the growing foreign public relations industry in the U.S., this remarkable text traces the impact that the political "image management" of other nations has had on the American foreign policy agenda. Documenting the evolution of these campaigns in both scale and sophistication, this book includes an analysis of the Justice Department's foreign agent registration records, numerous interviews with journalists, consultants, and key government officials, and a systematic assessment of media content to gauge the effectiveness of these attempts at news management. The author presents and tests elements of a general model of agenda-related communication effects, presenting case studies that illustrate the extent to which the American media are saturated with foreign diplomatic messages, including the recent effort of the Kuwaiti government-in-exile to influence public opinion in the U.S. during the Gulf War, and concludes with an inventory and discussion of the issues raised by the "export" of the knowledge-base and skills underlying new, sophisticated communication strategies now being employed on behalf of foreign interests. Based on fifteen years of exhaustive research, this book is ideal for courses in foreign policy, media, and politics.

Abstract: Methods and apparatus for enabling a node that does not support Mobile IP to roam from a first Foreign Agent to a second Foreign Agent are disclosed. In a Foreign Agent that supports Mobile IP, a method of registering a node that does not support Mobile IP with a Home Agent that supports Mobile IP includes detecting a node in a vicinity of the Foreign Agent, composing a registration request specifying a node ID associated with the node, and sending the registration request to the Home Agent. When the Home Agent receives the registration request from a first Foreign Agent, the Home Agent updates a mobility binding table to associate the first Foreign Agent with the node. In addition, the Home Agent notifies a second Foreign Agent to update its visitor table to reflect roaming of the node from the second Foreign Agent to the first Foreign Agent.

Abstract: A network system which provides each terminal user with differentiated service, dynamically changing service profiles even in the middle of a communication session. A service control database maintains service profile definitions. When a mobile node registers with a foreign agent to initiate a communication session, a service profile setting controller in the mobile node's home server sets up a service profile for the mobile user. When an event occurs within a service profile updating controller, it indicates that some control condition specified in the service profile is met. The service profile updating controller then makes access to the service control database to obtain a new service profile. The mobile node's foreign server forwards it to the foreign agent, to which the mobile node is attached. The service profile that has been established in relevant network nodes, including the home agent and foreign agent, is dynamically updated with the new one.

Abstract: A tunneling optimization is described in which packets are forwarded from a home agent to a mobile device by co-locating a foreign agent corresponding to a mobile device at the mobile device. When a mobile device acquires a new foreign agent, the mobile device notifies the home agent as to the corresponding foreign agent address. A packet received at the home agent having the mobile device as a packet header destination address is parsed and the foreign agent address is substituted for the mobile device address, and the packet is forwarded to the foreign agent. The foreign agent, upon receiving the packet, removes the foreign agent address and replaces the mobile device address as the packet header destination address. The packet is then forwarded to the mobile device.
