摘要： When load balancing (LB) for SIP message communication is performed across multiple SIP servers, the number of messages that must be processed by an LB server is reduced. The SIP LB server includes an LB management means which, if the previous hop source of a received request message is a terminal in the local domain, determines which SIP server to serve the terminal, and a redirect function which notifies the message source terminal in the local domain of the address of the serving SIP server. The SIP LB server further includes an LB management table which, if the previous hop source of a received request message is other than a terminal in the local domain, is searched to find a SIP server serving communication with a destination terminal in the local domain, and a stateless forwarding function which statelessly forwards the received request message to the resolved SIP server address.

摘要： Erroneous detection of a failure in spite of the absence of failure on the route on account of a communication delay is to be prevented. A node device detects a failure on the route to a remote node device is detected by a failure to receive a packet from the remote node device after the elapse of a determined detection time. The node device sets “remote system transmission interval×detection multiplier” to be a first detecting time on the basis of a packet transmission interval determined by negotiation with the remote node device. It also sets the sum of “remote system actual transmission interval ×detection multiplier” and “tolerable delay time” to be a second detecting time. The first detecting time and the second detecting time are compared, and what is longer is determined as the detecting time to be applied to actual operation.
摘要翻译：考虑到由于通信延迟而导致路由不存在故障，故障的错误检测是可以防止的。在经过确定的检测时间之后，通过从远程节点设备接收到分组的故障来检测节点设备检测到到远程节点设备的路由的故障。节点设备基于通过与远程节点设备协商确定的分组传输间隔将“远程系统传输间隔×检测乘数”设置为第一检测时间。它还将“远程系统实际发送间隔×检测乘数”和“可容忍延迟时间”的和设置为第二检测时间。比较第一检测时间和第二检测时间，将更长的时间确定为要应用于实际操作的检测时间。

摘要： If interaction between signaling gateways frequently occurs, it is possible that extended processings are executed redundantly on a path of signaling messages. To avoid such a redundancy, a consistent method is necessary for deciding a signaling gateway to execute an extended processing from among the signaling gateways. The signaling gateways, each time they receive a signaling message, calculate information about a path through which it is transferred. By passing the path information in addition to the signaling message to an extended processing program, the signaling gateways decide whether to execute the extended processing on the signaling gateways, on a session basis. A signaling gateway that has executed an extended processing adds information indicating a processing status to the signaling message to notify other signaling gateways of it.

摘要： A session relay apparatus for preventing the packet relay delay by detecting the start and end of the policy settable peer-to-peer communication is disclosed. The session relay apparatus for relay a session control message transmitted and received between communication terminals to control the peer-to-peer communication detects the start and end of the communication from the session control message, and acquires the information for identifying a session and the information on the peer-to-peer communication carried out on the session. Upon generation of a policy indicating the packet relay control process by a policy generating unit, edge nodes for passing the packet are searched for and the policy is distributed to the edge nodes. The policy is set in the edge nodes accommodating the communication terminals at the start of communication, and the policy setting is canceled at the end of communication.

摘要： The storage device is provided with a synchronization controller to realize synchronization control of information for the other storage devices when information is updated. This synchronization controller is further provided with a synchronization level registration table for registration and management of synchronization levels for every class of information and a synchronization interval registration table for registration and management of synchronization intervals of information pieces for the synchronization levels. Consequently, a load of communications may be alleviated by realizing common sharing/synchronization of information pieces among different systems and particularly by realizing loose common sharing/synchronization of information pieces depending on the characteristics of the information.

摘要： The multimedia call distribution system maintains call connection devices, a multimedia call distribution device, and terminal devices. When a call connection request is received, each of the call connection devices issues an inquiry to the multimedia call distribution device about a terminal device to which a call is to be connected. The call connection device connects the call to the terminal device as a response to the inquiry by the multimedia call distribution device The multimedia call distribution device monitors communication conditions of each terminal device about respective types of media, and selects one terminal device that can preform real-time communication and informs the call connection device that has issued the inquiry of the selected device as a response, when the inquiry is received from the call connection device, and when a type of media of the call connected by the call connection device that has issued the inquiry is a type of media that preform real-time communication.
