摘要： According to the present invention, an information network wherein, packets can be forwarded between entities on a network along a plurality of lines, each line carrying separate copies of information. If a portion of one copy of the information is lost due to line failure, for example, other copies flowing along different lines can be used to reconstruct the lost information. In a representative embodiment, a plurality of LAN lines respectively connect between terminals and LAN-to-LAN forwarding devices or between two LAN-to-LAN forwarding devices. The terminals or the LAN-to-LAN forwarding devices are respectively provided with multiple line transmitting units for respectively transmitting the same packets to the plurality of LAN lines substantially contemporaneously. There are also provided multiple line receiving units for respectively selecting any of the same packets sent from the plurality of LAN lines and receiving it.

摘要： A network apparatus according to the present invention is connected to a single server apparatus or a plurality of server apparatus via a link. The network administrator sets in advance the band volume to be used by a frame transmitted from each of the server apparatus within the range of the communication band volume possessed by the link. The network apparatus has a band controller that instructs each of the server apparatus to transmit a PAUSE frame. The network apparatus is also provided with a transmitter that transmits a PAUSE frame to each of the server apparatus via the link according to the instruction of the band controller. Each of the server apparatus receives the PAUSE frame transmitted from the network apparatus. Each of the server apparatus suspends frame transmission to the network apparatus for the suspension period set in the received PAUSE frame.

摘要： To reliably detect a failure even when the failure occurs at a part of a line or in a mating apparatus, a transmission control portion transmits a link-up signal for confirming connection by the mating apparatus to a transfer path during the period in which data is not transmitted, in accordance with the instruction from a line control portion. Receiving the link-up signal flowing through the transfer path, the reception control portion confirms that no failure exists in the mating apparatus and in the transfer path or in the apparatus, and sends this notice to the line control portion. When not receiving the link-up signal, the line control portion reports the failure to the mating apparatus by intentionally stopping transmission of the link-up signal through another transfer path. To examine the operation condition of the line, a specific signal that can be sent during the period in which the data is not transmitted, and represents whether or not the line is utilizable is used as the link-up signal.
摘要翻译：为了可靠地检测故障，即使发生在线路的一部分或匹配装置中的故障，发送控制部分在数据为期间的期间内发送用于确认由配对装置连接到传送路径的链接信号不发送，根据来自线路控制部分的指示。接收控制部分接收流过传送路径的链接信号，确认配对装置和传送路径或设备中不存在故障，并将该通知发送给线路控制部。当没有接收到链接信号时，线路控制部分通过有意地停止通过另一个传送路径的链接信号的传输来报告配对装置的故障。为了检查线路的运行状况，可以使用在不发送数据的期间可以发送的特定信号，并且表示线路是否可用。

摘要： In a method of distributing frame to a line during line aggregation communications, a transmission side data processing apparatus selects a line to which a frame is transmitted, so that the transmission data amounts of respective lines become uniform. Order information is inserted into the transmission frame and the frame is transmitted to the selected line. A reception side data processing apparatus sequentially executes a reception process for a received frame in accordance with the order information derived from each received frame.

摘要： The present invention provides techniques to increase the efficiency of communication between computer systems. One embodiment of the present invention provides a method for communicating a first information item having a first data length of a plurality of data lengths, from a first device to a second device via a local area network. The first data length is determined based on a first data length restriction of the second device. Another embodiment enables a high-speed transfer of a large volume of data on a server to another server, without stopping the communication between the server and a client. This embodiment uses the limitation on data length of the destination system to limit the length of the data sent by the source system. In addition while standard length data is exchanged between client and server, extended length data is exchanged between servers.

摘要： In an information network having a complex structure made of a logical network and also a physical network, such an information network is constituted so as to realize a multicast service capable of not increasing an amount of a network traffic larger than a necessary traffic amount. This information network contains a plurality of information relay apparatuses for relaying information among a plurality of VLANs (Virtual Local Area Networks), a network for connecting these information replay apparatuses to each other, a multicast server and a plurality of terminals, belonging to an arbitrary VLAN of these VLANs. A multicast relay processing unit, a multicast address learning processing unit, and a multicast learning table are provided in each of these information relay apparatuses so as to register a predetermined relay destination of a multicast communication. Even in such a case that the VLAN structure is made complex irrespective of the physical network structure, it is possible to distribute such a multicast packet suitable for the physical network structure.

The network relay device includes: a control module that sends and receives a control frame signal to and from the specific network device, selects either of a master mode and a backup mode based on at least the control frame signal sent from the specific network device, and changes a working state according to a result of the selection; and a communication module that is under control of the control module to open a port and enable data transmission via a line linked to the port in the case of setting a master state to the working state, and to block off the port and disconnect the line linked to the port in the case of setting a backup state or another non-master state to the working state. The control module changes the working state from the backup state to a first intermediate state in response to selection of the master mode, determines whether the specific network device is in the backup state, based on the control frame signal sent from the specific network device, and changes the working state from the first intermediate state to the master state after confirmation that the specific network is in the backup state.
