Publication number: 20140254600Abstract: A transport system comprises a transport apparatus, which is used to construct a transport network using MPLS-TP; and a control apparatus for establishing a path in the transport network. The transport apparatus is coupled to a transfer apparatus, which is used to construct a transfer network using a network protocol different from an MPLS-TP protocol and uses the network protocol to establish a path in the transfer network in an autonomous distributed manner. The control apparatus and the transfer apparatus use the network protocol of the transfer network to transmit/receive, via the transport apparatus, control messages for controlling the transfer network. The transport apparatus avoids notifying the transfer apparatus of the fact that the control apparatus is not in a normal state, in a case where the path established in the transport network is determined as the normal state, even the control apparatus is determined as the abnormal state.Type: ApplicationFiled: February 27, 2014Publication date: September 11, 2014Applicant: HITACHI, LTD.Inventors: Takeshi SHIBATA, Kiyotaka TAKAHASHI, Masahiro KIMURA

Patent number: 8817794Abstract: It is ensured to prevent a user from misrepresenting a time stamp, and to send out packets in sequence in which the packets are accepted to all users who are geographically isolated from each other. A unique time stamp impartation function is realized by respective communication devices on a net inside an administrative responsibility range of a communication common carrier, hardly accessible by a user. If a packet with a time stamp imparted by a subscriber terminal, provided thereto, is received, the respective communication devices positioned on the net inside the administrative responsibility range nullify the relevant time stamp in order to prevent misrepresentation of the time stamp, by a user outside the administrative responsibility range, and restores the packet from the subscriber together with the time stamp when transferring the packet to the outside of the administrative responsibility range.Type: GrantFiled: January 12, 2012Date of Patent: August 26, 2014Assignee: Hitachi, Ltd.Inventors: Kiyotaka Takahashi, Takumi Oishi, Yoshihiro Ashi

Publication number: 20130315251Abstract: A communication device on a time equivalence assurance network that guarantees the receiving sequence of packets sent to all users so that even if a user session is re-sent, a function operates to alleviate the resultant effects and make the send and receive timing approach the initial timing. An edge communication device on a provider network identifies the sessions of each user subscriber terminal, and stores and monitors the time information attached by a sequence information attachment function. Even if a packet is resent, the packet will at this time be resent with attached sequence information based on the past time originally attached to the packet, and not sequence information based on the current resending time.Type: ApplicationFiled: November 14, 2012Publication date: November 28, 2013Applicant: Hitachi, Ltd.Inventors: KIYOTAKA TAKAHASHI, YOSHIHIRO ASHI

Publication number: 20130272141Abstract: A transport system comprises a plurality of transport devices to be and a central control computer. The transport devices are coupled to a first communication path which is established autonomous and decentralized manner by communication devices. The central control computer establishes a second communication path in a transport network including the plurality of transport devices, and sets a correspondence between the first communication path and the second communication path to one of the plurality of transport devices. One of the plurality of transport devices transmits a coupling check request for checking coupling from the communication device to a loopback point to the central control computer. The central control computer transmits, depending on a result of the check of the coupling executed by the one of the plurality of transport devices, a coupling check response to one of the plurality of transport devices which has transmitted a coupling check request.Type: ApplicationFiled: March 1, 2013Publication date: October 17, 2013Applicant: Hitachi, Ltd.Inventors: DAISUKE MASHIMO, Kiyotaka Takahashi, Takeshi Shibata

Patent number: 8145152Abstract: A gain temperature compensation circuit producing a relatively small loss of power, and enabling modification of a variation width of the attenuation amount in a predetermined temperature range is provided. A gain temperature compensation circuit includes a circulator and a thermistor. The circulator outputs a signal being input to a first port to a second port, and outputs the signal being input to the second port to a third port. The thermistor being connected to the second port reflects the signal being output from the second port by varying the power of the signal according to temperature, so as to input to the second port, in order to adjust the attenuation amount of the signal.Type: GrantFiled: December 23, 2008Date of Patent: March 27, 2012Assignee: Fujitsu LimitedInventors: Kiyotaka Takahashi, Yasushi Seino

Publication number: 20110222541Abstract: Edge nodes form point-to-point communication paths with one another. Multiple communication paths set at one port of an edge node and/or a relay node are regarded as a group. Identification information of the port and identification information of a group that outputs a frame inputted into the port are previously stored as associated with each other. If the destination address of a frame inputted into the port is unknown, an outgoing interface search unit identifies at least one group corresponding to the port. The frame is outputted from a port corresponding to the identified group.Type: ApplicationFiled: December 28, 2010Publication date: September 15, 2011Applicant: Hitachi, Ltd.Inventors: Takumi OISHI, Norihisa Matsumoto, Kiyotaka Takahashi, Hideki Endo
