| 20080298370 | ROUTER - Even when session control traffic such as SIP traffic to be unitarily subjected to QoS management by a manager of a session control network such as an SIP network, and loopback traffic to be freely subjected to QoS management by users coexist, QoS processing can be appropriately performed. The edge router checks a routing table and the address information of an SIP message to derive an SIP stream direction. The edge router timely selects a table that can be set by only SIP network managers, and a table that can be set by user network managers as well, determines QoS setting information by collating other SIP/SDP message information, and sets it in a QoS function unit. | 12-04-2008 |
| 20090150567 | ADDRESS TRANSLATOR, MESSAGE PROCESSING METHOD AND EQUIPMENT - An address translator includes an SIP message detecting function. Upon detection of an SIP message, the address translator sends the SIP message to an SIP address translator. The SIP address translator extracts addresses for translation, and makes a query to the address translator. The SIP address translator translates an IP address included in the SIP message, using translation information of the address translator. Thus, an SIP communication is accomplished between terminals belonging to different regions in association of the address translator and the SIP address translator. | 06-11-2009 |
| 20100122338 | NETWORK SYSTEM, DHCP SERVER DEVICE, AND DHCP CLIENT DEVICE - When customer-premises communication equipment connected to a home gateway device is about to establish IP communication with a server on a network, the present invention enables the server to establish communication after verifying that the physical connection location of the communication equipment is authorized. When a DHCP server issues an IP address to the home gateway device, the DHCP server not only passes a circuit-ID-based identifier to the home gateway device, but also transmits the identifier and information about the home gateway device to the server. Upon receipt of the identifier through the home gateway device, a communication equipment requests to establish IP communication with the server by using the identifier and the information about the home gateway device to which the communication equipment is connected. This permits the server to check whether the connection path of the communication equipment that has requested to be connected is proper. | 05-13-2010 |
| 20100241861 | DHCP CLIENT SERVER SYSTEM, DHCP CLIENT DEVICE AND DHCP SERVER DEVICE - A conventional DHCP authentication method could not cope with a one-phase two-messages DHCP sequence involved in a Rapid-Commit option. Further, in the conventional DHCP authentication method, it is possible to replay attack at lease renewal timing and, when information used in a retransmission method between a client and a server becomes the loss of synchronization, the conventional DHCP authentication method cannot detect the loss of synchronization and has such a problem that unnecessary traffics are continuously produced. A DHCP client device includes a means that stores a user ID, a secret key, and retransmission detection method (RDM) information. A DHCP server device includes a database that is available for the retrieval of a secret key and RMD information based on a user ID as a key or an access mechanism to an external DB with the same function as that of the database. | 09-23-2010 |
| 20100293285 | Method of translating protocol at translator, method of providing protocol translation information at translation server, and address translation server - A translator is connected to a first network for transferring data in a first protocol, to a second network for transferring data in a second protocol, and to a translation server to which other translators are connected, for retaining translation information for a protocol translation between the first protocol and the second protocol. The translator generates a second address in the first protocol corresponding to a first address in the second protocol provided to a terminal accommodated in the second network. It retains a correspondence between the first address and the second address as the translation information and registers the correspondence at the translation server. | 11-18-2010 |

The SIP address translator translates an IP address included in the SIP message, using translation information of the address translator.
