摘要： Herein disclosed is a data communication system in which a plurality of node equipments are linked to a common signal transmission line so that the data may be communicated between the respective node equipments. The data communication system is characterized: in that at least one of the node equipments includes means for generating and transmitting repeatedly for a predetermined period the channel which contains a data transmission bit and a validity bit for the former bit; and in that each of the node equipments linked to the common signal transmission line partly sends out the data through said channel and partly makes the validity indicating bit indicate an invalid state, when the speed of said data is so slower than the predetermined period of said channel that the data to be sent out for the predetermined period are out of time thereby to make it possible to effect the data transmission at an arbitrary speed shorter than said predetermined period.Herein also disclosed is a data communication system in which a plurality of node equipments are jointed by a common transmission loop line and in which the information of multiple channels is repeatedly transmitted for a predetermined period to said transmission loop line so that the channel information may be sent and received between terminal equipments linked to said node equipments. The data communication system is characterized in that an identical pattern for synchronization is inserted into and transmitted by the plural head channels of each period so that the synchronization is effected at each of said node equipments by detecting the synchronizing pattern received by means of a detecting circuit.
摘要翻译：这里公开了一种数据通信系统，其中多个节点设备链接到公共信号传输线，使得可以在各个节点设备之间传送数据。数据通信系统的特征在于：节点设备中的至少一个包括用于在预定周期内重复生成和发送包含前一比特的数据传输比特和有效比特的信道的装置; 并且，连接到公共信号传输线路的每个节点设备部分地通过所述信道发送数据，并且部分地使有效指示位指示无效状态，当所述数据的速度比所述数据的预定时间慢的时候在预定时间段内要发送的数据的时间是超时的，从而使得可以以比所述预定周期短的任意速度实现数据传输。这里还公开了一种数据通信系统，其中多个节点设备由公共传输环路线连接，并且其中将多个信道的信息重复发送一段预定时间段到所述传输环路线，使得信道信息可以是在与所述节点设备连接的终端设备之间发送和接收。数据通信系统的特征在于，用于同步的相同模式被插入每个周期的多个头信道并由其发送，从而通过检测通过检测电路接收的同步模式来在每个所述节点设备处实现同步。

摘要： Frontend LANs connecting plural stations are connected to plural nodes of a backbone LAN respectively. The backbone LAN is constituted by plural physical or logical links, and each node corresponds to each frontend LAN. A first data block is segmented into one or plural second data block units of fixed length and transferred to destination nodes, a bridge is provided in order to assemble the second data blocks into the first data block. The bridge can transmit the second data blocks to arbitrary links, and the receiving is performed through one link. The bridge a decoder also has a decoder for decoding whether the learning should be performed or not, based on the learning indication information existing in the second data block including the routing information.

摘要： Out of viewers of the same content, multi-user talking service is provided to only viewers who wish to enjoy the content in a large number of people. Only when an address of a terminal 4, 5 that has transmitted a request for participation in multi-user talking is registered in a viewer management DB (which manages viewers of contents), a content distribution/multi-user talking service center 1 registers the above-mentioned address into a participant management DB (which manages participants in multi-user talking) associating the address with identification information of a content that is registered in association with the address in question in the viewer management DB. Then, for each content, respective pieces of talking data received from addresses registered in association with identification information of said content in the participant management DB are synthesized to generate multi-user talking data, and generated multi-user talking data is transmitted to each of said addresses.

摘要： Switches create and manage routes with route control protocols such as BGP-4, PNNI, etc. and a route management apparatus is notified of the information of the routes, created by these protocols, and the route management apparatus verifies the validity of a route of which the apparatus is notified by a switch based on the route information of the whole network composed of the plurality of pieces of information given by respective switches and the management policy set by a network manager. In the verification of validity, it is confirmed that the transmitted data are able to arrive at the destination securely and the set route is not against the management policy, and the route-usage-permission-notice of a route confirmed of its validity by the route management apparatus is transmitted to respective switches. Thereby, in the route control of a network using a route control protocol, it is made possible to prevent the occurrence of an abnormal route caused by the difference in the speed of operations of respective switches or an erroneous setting of a switch.

摘要： In a service system including client apparatuses for issuing a service request and server apparatuses for receiving a service request and providing service, there is provided a data relaying apparatus for relaying data communication between them. In response to a service request, the data relaying apparatus establishes a connection from the client apparatus to the server apparatus (destination). The data relaying apparatus relays data communication between the client apparatus and the server apparatus by using the established connection. The data relaying apparatus manages a number of connections established to each of the server apparatuses. In response to a service request, the data relaying apparatus accepts or refuses the service request so as to make a number of connections to the server apparatus equal to or less than a predetermined number, and notifies a user refused relaying of a service request that relaying is possible.
