Abstract: The present disclosure discloses a method and device for advertising routing information and a method and system for implementing packet routing. The method for advertising routing information includes a routing information advertising device that obtains its address information; the routing information advertising device adds the address information to routing information to advertise; and the routing information advertising device advertises the routing information that carries the address information. With the technical solution of the present disclosure, the number of routing tables in a backbone network may be greatly reduced. This minimizes the rise of router costs and effectively avoids slower route convergence. In addition, a router in the backbone network can dynamically obtain address information of a core router that advertises an aggregate prefix, such that it may be easier to implement registration, update and query the mapping between a more detailed address prefix and a border router.

Abstract: A communication control system capable of reducing the traffic amount, CPU's processing load and channel bands related to a location registering process. In this system, a paging part (303) of a base station apparatus (300) receives a call request message transmitted from an access gateway apparatus (200) and addressed to a wireless terminal apparatus, and generates a call response message indicative of accommodating the wireless terminal apparatus. An MIP location registering part (304) registers an IP address established at the transmitting source of the call request message, and generates a location registration request message that requests a registration of an IP address established at the local base station. A packet combining part (305) generates and transmits a combined packet, which is obtained by combining the call request message with the location registration request message, to the access gateway apparatus (200).

Abstract: A communications network gateway receives a stream of information formatted to be compatible with a synchronous structured network.

Abstract: A gateway receives network presence information regarding a mobile station. The network presence information is based, at least in part, on status messages that a network access server, such as a packet data serving node (PDSN), sends, for example, to an accounting server. The network presence information identifies the mobile station, such as by Internet Protocol (IP) address, network access identifier (NAI), and/or mobile directory number (MDN). When the gateway receives a request from a mobile station to access a content server, e.g., an HTTP GET request, the gateway inserts identifying information, such as NAI and/or MDN, into the request to identify the mobile station to the content server.

However, the data packet is transmitted between the Home Agent and a VPN headend via a VPN tunnel.

A method is provided for permitting packet based data transmission between a first client computer C1 protected by a first NAPT or NAT firewall and a second client computer C2 protected by a second NAPT or NAT firewall to traverse the first and the second firewalls. The method can also be applied to other devices, such as routers, using NAT or NAPT.

Thus, the second network element sets its mode dependent on whether a procedure like processing of a location request has to be performed or has not to be performed, or, whether a procedure has been performed or not. The network elements can be Call State Control Functions (CSCF).

Abstract: The present invention is related to synchronizing status information of an IMPS client in a wireless communication system. A server, which manages status information using version information, compares status information of contacts stored in association with version information received from a client to current status information. The server transmits changed status information to the corresponding client. Preferably, the server stores the current status information in association with new version information and informs the client about the new version information. The server stores at least two of the latest version information and respective status information. Accordingly, when a status information response message is lost in its transmission and the server receives a request for the status information from the client, the changed status information can be obtained.

Abstract: Example embodiments allow a local network client to access information about a shared gateway to determine its actual amount of bandwidth consumption. The client can also obtain the total capacity of such shared gateway. Using its knowledge of its own bandwidth consumption, it can determine the other local network clients' usage of the shared gateway. With all of this information, i.e., total capacity of the shared gateway, the actual usage of the shared gateway, and the usage by other clients within the local network, the client can adjust or throttle background file transfers in order to keep the actual data transfers across the shared gateway within a reasonable percentage of the total capacity available. That is, a client will give priority to other local network computing machines' usage of the shared gateway by adjusting data transfers for its own background transfer system based on usage across a shared gateway.

The core router configured with an FDL performs proactive delay processing for the burst to be overlapped after predicting that the burst will be overlapped on the link to be protected, thus reducing the probability of burst conflict on the downstream link to be protected.

Therefore, the FDL configured in the network is brought into full play, and the probability of burst conflict is reduced.
