摘要： PROBLEM TO BE SOLVED: To properly assign a line with a guaranteed communication quality to a terminal.SOLUTION: When switching to a first line is requested from a terminal, a communication apparatus determines whether the number of presently connected terminals that is the number of terminals connected presently to the first line exceeds the upper-limit number of terminals connectable to the first line. If the number of presently connected terminals exceeds the upper-limit number, the communication apparatus cuts off the connection, to the first line, of at least one of the terminals presently connected to the first line, and thereafter assigns the first line as the connection destination of the terminal which has requested the switching.

摘要： PROBLEM TO BE SOLVED: To obtain band reduction in tunnel communication.SOLUTION: In order to establish tunnel communication between a client device located in a first communication area and a server device located in a second communication area, a relay device transmits and receives packets to/from a tunnel communication establishment device located in the first communication area. The relay device includes: a decision unit for deciding the necessity of the degeneration of a real payload part in a reception packet transmitted from the client device or the server device on the basis of a preset threshold information; a conversion unit for, on decision that the degeneration of the real payload part in the reception packet is necessary, generating pseudo payload identification information to set a pseudo payload part, including the generated pseudo payload identification information and information indicative of a degeneration existent state, in substitution to the real payload part of the reception packet; and a transmitter unit for transmitting the packet including the pseudo payload part to the tunnel communication establishment device.

摘要： PROBLEM TO BE SOLVED: To prevent concentration of load on a distribution server by holding the equal number of data blocks in peers distributed on a network, in a peer-to-peer streaming delivery method, a distribution server apparatus, and a client apparatus.SOLUTION: Actual content data is divided into plural data blocks. The data blocks are held by the distribution server 10 and the peers 21 to 25. The data block of the content is distributed to a client 11 from each of the peers 21 to 25 or the distribution server 10. The client 11 requests each of the peers 21 to 25 to distributed the data blocks. When the peers receives a reply indicating that the data blocks are undeliverable, the client 11 transmits a request to distribute the undeliverable data blocks to the distribution server 10. Upon receipt of the request to distribute the data blocks, the distribution server 10 distributes the data blocks to the client 11, and at the same time, instructs the client 11 to hold the data blocks.
摘要翻译：要解决的问题：通过在对等流传送方法，分发服务器装置和客户端装置中保持在网络上分布的对等体中保持相等数量的数据块来防止分发服务器上的负载集中。解决方案：实际内容数据被分成多个数据块。数据块由分发服务器10和对等体21至25保持。内容的数据块从对等体21至25或分发服务器10中的每一个分发给客户机11.客户端11请求每个对等体21到25分发数据块。当对等体接收到指示数据块不可投递的回复时，客户端11发送分发不可投递数据块的请求到分发服务器10.在接收到分发数据块的请求时，分发服务器10分发数据到客户端11的块，并且同时指示客户端11保存数据块。

摘要： PROBLEM TO BE SOLVED: To perform leveling control of signal traffic for updating a registration effective time of registration information set from a terminal to a SIP server and a presence server within an effective time about a traffic leveling control method and a server in a telephone system through an IP network by SIP (Session Initiation Protocol) or SIMPLE (SIP for Instant Messaging and presence Leveraging Extensions) protocol. SOLUTION: A server for preforming service control is configured so as to store a service request including registration information and a registration effective time from a user terminal in a table, calculate a relative time with the present time as reference from the registration effective time, calculate the scheduled number of receiving update signals corresponding to the relative time from the table, calculate a time corresponding to the relative time, calculate a limitation value of the number of receptions per unit time in each time difference from the table, and determine the registration effective time to be a base of the relative time as a proper time when it is detected that the calculated scheduled number of receptions is less than the limitation value of the number of receptions.
