  • Patent number: 7061911
    Abstract: An edge device is disposed at an entrance of a MPLS domain. The edge device, when receives a packet attached with a local label from a communication device of users side, extracts a destination label corresponding to the local label from a label learning table, rewrites the local label in the packet with the extracted label, and transmits the packet to a neighboring LSR corresponding to the extracted label within the MPLS domain.

  • Patent number: 6813245
    Abstract: A method for detecting a congestion state in an ATM network without modifying the ATM network. A transmitter-side endsystem sends. to a receiver-side endsystem an amount of transmission data transmitted to a logical connection in the ATM network. The receiver-side endsystem counts an actually received amount of reception data, and compares the amount of transmission data with the actually received amount of reception data to detect the congestion state. Instead of the amount of the transmission data, a notification of completion of transmission of a predetermined amount of data may be sent to the receiver-side endsystem. In this case, the predetermined amount is stored in advance in both the transmitter-side and receiver-side endsystems, and receiver-side endsystem compares the predetermined amount with the actually received amount of reception data to detect the congestion state until the notification is received after a previous notification.

  • Publication number: 20030167343
    Abstract: A communications system which switches from an active server to a backup server without delay or interruption, thus achieving better quality of Voice over IP (VoIP) service. The system employs a first server to centrally manage client address information and a second server to back up the first server. They serve a plurality of clients, each having a client address registration unit and a communication controller. The client address registration unit registers the client with both the first and second servers by sending client address information thereto. The communication controller receives a resolved destination IP address and an allocated network bandwidth from the first server in normal situations, and from the second server when the first server is unresponsive.

  • Patent number: 6125123
    Abstract: A signaling method for a communication uses a signaling protocol, and includes the steps of making a re-connect request with respect to a receiving side end system from a certain system which is coupled to the receiving side end system, in place of a transmitting side end system, when the receiving side end system rejects a call connect request from the transmitting side end system, so that there is no need for the transmitting side end system to make a re-connect request even when the connect request from the transmitting side end system is rejected by the receiving side end system, and the connection can be established within a relatively short time.
