Abstract: A mobile Internet Protocol (IP) system and a data routing method of the mobile IP system are disclosed. According to the present invention, even if a mobile node moves from a first foreign agent to a second foreign agent while it receives data packets from the first foreign agent, the first foreign agent keeps storing the data packets it its buffer, and it sends the stored data to the second foreign agent indicated in a notification message received from the mobile node. Therefore, the host does not need to retransmit the data packets to the second foreign agent again. This will greatly increase reliability of the data transmission in the IP system and can reduce the overhead of the whole system.

Abstract: A dual-stack host (430) is provided on a multicast network (470) using first and second protocols (450, 460). The dual-stack host (430) detects a first multicast request from a source host (410) to a destination host (420) using a first protocol. The dual-stack host (430) initiates a timer. When the timer expires, the dual-stack host (430) sends a second multicast request message to the destination host (420) using each of the first and second protocols. The dual-stack host (430) monitors whether the destination host (420) responds using one or both of the first and second protocols and determines whether protocol translation is necessary to allow the source and destination hosts to communicate. If required, the dual-stack host (430) then invokes protocol translation to provide the source host (410) with a synthesized address for communicating with the destination host (420).

Abstract: During the reception of a content delivery service, if the service is continued by switching a communication path, a temporary interruption occurs upon the switching of a session. There are cases where the same service cannot be continued if the communication speed of the communication path prior to switching is greatly different from that of a communication path after switching. Sessions for delivering two contents each encoded from the same source data, having different bit rates, and temporally synchronized with each other are established simultaneously with respect to a client terminal. The sessions are switched at the client terminal based on information on the respective times of content data from the two sessions such that a temporal continuation is provided therebetween.

Abstract: A plurality of terminals connected to a network distribution-process update notifications of information and data obtainment, thereby constructing an information notifying network which needs no server. In the network constructed by a plurality of terminals, when the user updates the information on the terminal, each terminal functions as an information provider terminal for informing another terminal that the information has been updated and transferring the updated information, and when another user updates the information on another terminal, each terminal functions as an information receiver terminal for receiving the update notification from the information provider terminal and the updated information.

The interface link layer device configured to simulate time critical self-ID packets to be effected on the first sub-network based on received information about one or more nodes local to the second sub-network.

Abstract: A method of determining a geographic location of an Internet user involves determining if the host is on-line, determining ownership of the host name, and then determining the route taken in delivering packets to the user. Based on the detected route, the method proceeds with determining the geographic route based on the host locations and then assigning a confidence level to the assigned location. A system collects the geographic information and allows web sites or other entities to request the geographic location of their visitors. The database of geographic locations may be stored in a central location or, alternatively, may be at least partially located at the web site. With this information, web sites can target content, advertising, or route traffic depending upon the geographic locations of their visitors. Through web site requests for geographic information, a central database tracks an Internet user's traffic on the Internet whereby a profile can be generated.

Abstract: Mechanisms for enforcing a message exchange pattern. When two computing systems communicate in order to accomplish a particular task, they engage in a particular message exchange pattern. Given certain progress through the message exchange pattern, the message exchange pattern may restrict which computing system may send what kind of messages. Each computing system tracks progress through the message exchange pattern by, for example, using a state transition tree in which each node represents a state of the message exchange pattern, and in which transmission or receipt of certain messages may cause state transitions. A computing system then only transmits messages if appropriate given the current tracked progress through the message exchange pattern.

The core functionality provided by the application may be preserved between the client and the server wherein improved network performance may provided along with improved offline service capabilities.

Abstract: A system and method for performing client-server transactions includes an application interface, located at a client, which manages connections between the client and a server. The application interface receives a request from an application program, opens a connection with the server, sends a message that includes the request over the connection, and holds the connection open for at least a timeout period. If the application interface receives another request destined for the server during the timeout period, it sends another message with the new request over the open connection. If the application interface receives one or more requests that are part of a transaction, the application interface assigns a transaction identifier to the transaction. The transaction identifier and a sequence indicator are included in each message with each request.

Abstract: A protocol emulator includes an executable emulation application configured for promiscuously detecting IP frames on a network interface. The executable emulation application generates response IP frames for each corresponding detected IP frame. The protocol emulator also includes a raw socket configured for outputting each response IP frame onto the network interface. Hence, the protocol emulator minimizes use of UNIX kernel resources by eliminating IP filtering of received IP frames from the network interface, and by using a raw socket for sending a response IP frame generated by the emulation application instead of the socket layer or the kernel. Hence, the minimal use of UNIX kernel resources enables scalable emulation of multiple logical IP addresses, effectively enabling an unlimited number of IP devices to be emulated without assignment of IP addresses to respective sockets.

A new XTP Protocol is proposed as another aspect of the invention, which is usable in a protocol stack for the Iu-PS (packet switched) implementation as well as over the Iu-CS, Iub, and Iur Interfaces.

Abstract: A user request processing method and apparatus, using an upstream channel, is provided, in which if a user request of predetermined processing for some predetermined nodes in interactive multimedia contents services, preferably, in an MPEG-4 binary format for a scene (BIFS) scene occurs, the user terminal forms an upstream channel message for the BIFS scene and transmits the message to the server through upstream channels, and the server processes and encodes the corresponding BIFS scene nodes and then transmits the nodes to the terminal. According to the methods and apparatuses, by properly handing events of user requests on partial elements in an arbitrary multimedia content provided for the user as interactive multimedia contents services, predetermined elements can be selectively processed. Therefore, information volume to be transmitted for restoration from an error can be minimized, and the terminal can quickly receive restored information.

Abstract: A method and system enter a correction for a previously sent message, determine whether to send a complete corrected message or a message correction specification, and send the selected message to a messaging server. The messaging server receives the message correction specification and a message identifier (ID), and sends the message correction specification and the message ID to a recipient client system if a message with a corresponding message ID has previously been sent to the recipient client system. Then, the recipient client system receives the message correction specification and message ID, retrieves the message with a corresponding message ID from its conversation log, corrects the message, updates the conversation log, and activates an alert to notify a user of an update. If the message has not previously been sent, the messaging server corrects the message and sends the corrected message and the message ID to the recipient client system.
