摘要： PURPOSE:To improve a message communication speed between processors by indicating message storing and reading areas by pointers to prepare the prescribed number of message transferring areas. CONSTITUTION:At the time of detecting the existence of a free area in a transmission area 11 based upon the values of 1st and 2nd pointers 12, 21, a transmitting side processor 13 stores a transmission message in a storing area 11-1 indicated by the 2nd pointer 21, sets up a flag 10 in the area 11-1 to an untransmitted state and updates the 2nd pointer 21 to a value indicating the succeeding storing area 11-2. When the flag 10 in the area 11-1 is turned to a transmitted state, the 1st pointer 12 is updated to a value indicating the area 11-2. On the other hand, a receiving side processor 25 transfers a message in the are 11-1 to a receiving area 24 through a data transferring mechanism 23 at the time of confirming the untransmitted state by a 3rd pointer and then updates the 3rd pointer to a value indicating the succeeding storing area.

摘要： PURPOSE:To decide a frame relay destination at a high speed by receiving a frame to decide a relay destination network and rearranging the connection of plural relay table entries depending on the frequency of use. CONSTITUTION:Every time a repeater 1 receives a frame and an entry retrieval device 3 retrieves a relay control table entry, an entry revision device 42 rearranges a control table entry of a relay control table entry group 4 or a grouped relay control table entry. That is, when a frame of same destination address is continuously received, the rearrangement of the relay control table entry is executed by the reception of one frame. The relay control table entry used to retrieval of the destination network of this frame is rearranged to be retrieved with priority from next time. Thus, the relay destination network in the reception frame is decided at a high speed.

摘要： PURPOSE:To attain efficient relay by transferring each information between the network and a communication module to a corresponding destination based on destination information through the control of transmission reception or storing the information to a buffer and managing addresses of reception and transmission information. CONSTITUTION:Each bus control circuit 104 controls transmission reception via a module bus 109 between networks 108a-108d and communication modules 102a, 102b whose transmission reception is controlled by each port control circuit 107. An information processing circuit 103 transfers the information received by the circuit 107 to a corresponding communication module based on additional destination information and stores it to a buffer 105 while dividing the information into fixed length blocks. Addresses of reception and transmission information in the buffer are managed by transmission reception management tables 116, 117, 148, 149 corresponding to the network and in the port side modules for each block. Thus, the re-transmission due to deficient capacity of the buffer 105 is avoided without reducing the relay processing performance of the packet and the relay efficiency is improved.

摘要： A user terminal sends a resource reservation request message in which time information indicative of time to perform a communication is designated to a switching node to which the self user terminal is linked. The switching node manages a reservation state of each of resources which can be used by the self switching node among resources of a network together with time information indicative of time when a communication using the resource is performed. When the resource reservation request message is received, an unreserved resource is obtained at a time indicated by the time information designated in the resource reservation request message, the obtained resource is reserved, and a resource reservation result notice message indicative of the reservation result is returned to the user terminal. A resource management server is also provided so as to reserve a network resource with a simple operation. The reservation can be performed in consideration of priority and cost of a communication. Reservation information can be always recognized by a client. When resource reservation is failed, an alternative plan is automatically calculated and presented.

摘要： PROBLEM TO BE SOLVED: To discriminatingly use the environments of one application according to an IPv6 address in a single end terminal. SOLUTION: The end terminal 100 manages a plurality of environments of applications by making the application identifiers and user identifiers correspond to each other, and when prefix information is distributed from a CPE router 101, the end terminal generates the addresses by the managed application identifiers and user identifiers, makes the environments and the addresses correspond to each other through an address generation management table 900, and sets an address assigned to a socket for communication as its own address. Consequently, the environments of one application can be used discriminatingly depending upon the IPv6 address. COPYRIGHT: (C)2005,JPO&NCIPI
摘要翻译：要解决的问题：根据单端终端中的IPv6地址区别地使用一个应用的环境。解决方案：终端100通过使应用标识符和用户标识符彼此对应来管理多个应用环境，并且当从CPE路由器101分发前缀信息时，终端终端通过被管理的方式生成地址应用标识符和用户标识符通过地址生成管理表900使环境和地址彼此对应，并且将分配给用于通信的套接字的地址设置为其自己的地址。因此，一个应用程序的环境可以根据IPv6地址区分使用。版权所有（C）2005，JPO＆NCIPI
