摘要： A failure is detected in a middle path of communication information received from one communication network. When the communication information received from the one communication network is relayed to another communication network, information is output to the other communication network by storing information about the failure detected from the communication information received from the one communication network in a header of communication information to be output to the other communication network.

摘要： An MPLS-VPN (MultiProtocol Label Switching-Virtual Private Network) service network of the present invention includes an interface identifying device. The Interface identifying device includes a virtual router belonging to a preselected VPN and an MPLS label operating section for stacking or removing MPLS labels on or from an IP packet received from the virtual router. The label operating section is made up of a first-stage label operating section for stacking on an IP packet received from a customer an MPLS label for transferring the packet over the network and a second-stage MPLS label operating section for executing label operation for identifying a virtual interface. The network constructs a virtual interface at each virtual router for allowing a routing protocol to operate between user sites that belong to the same VPN.

摘要： In a trunk network, each node, when notified from another node of a change in the state of a group to which external connection ports belong, changes the states of the external connection ports to cause external devices to detect the failure of the transmission route. A port state monitor unit classifies external connection ports into groups in advance and stores the correspondence of the external connection ports and the groups. The port state monitor unit then detects changes in the states of external connection ports. When a change of the state of any external connection port is detected in the port state monitor unit, a group state management unit reports state information that includes the states of groups that correspond to the external connection port to other nodes that make up the trunk network. Upon receiving state information from any other node, the group state management unit, in accordance with the states of groups that are included in the state information, changes the states of external connection ports that belong to these groups.

摘要： A color separation optical system for a color television camera of relay lens type in which a set of color separating optical elements are provided between a single first relay lens and three second relay lenses for three primary colors. The first relay lens is located substantially on the image plane of the taking lens of the television camera. A field lens is provided between the taking lens and the first relay lens. The power of the field lens is determined according to the focal length of the taking lens. The field lens is removed when the exit pupil of the taking lens is registered with the entrance pupil of the first relay lens. In this case, the first relay lens is axially moved toward the taking lens to make the front focal plane of the first relay lens registered with the image plane of the taking lens. The axial movement of the first relay lens is conducted by means of a mechanism which is operable from outside of the television camera.

摘要： In a data transmission system having a plurality of transmitters connected in a ring configuration, a band monitoring unit in each of the plurality of transmitters monitors the bandwidths of a first and a second transmission path between one of the transmitters that comprise the ring and a first and a second transmitter on both sides of said transmitter, respectively. A protection execution unit executes protection processing by setting up a bypass path for each of the first and second transmission paths. Further, when the bandwidth of the first or second transmission path acquired by the band monitoring unit decreases below a threshold, and only when any one of the transmitters comprising the ring and the other transmitters is not executing protection processing, the protection execution unit executes protection processing for the first or second transmission path which is determined to have a bandwidth smaller than the threshold.
