摘要： An external network relay device measures group movement parameters that are used to determine whether the need exists to change the group affiliation of internal network relay devices. When the results of measuring the group movement parameters meet conditions that have been set in advance, the external network relay device transmits group movement notification messages instructing group movement to the internal network relay devices of its own group and causes the internal network relay devices to change to other groups.

摘要： A phase adjustment circuit for display apparatuses operates to vary the phase of an input sync signal to produce a pseudo sync signal for use in positioning an image at the center of a display screen. The circuit comprises a voltage comparator (50) having two input terminals thereto maintained at the same d.c. voltage, and one input terminal thereto is supplied through a d.c. blocking capacitor (C.sub.2) with a saw-tooth wave signal (P.sub.1) obtained by integrating the input sync signal, whereby a pulse having an edge of its pulse waveform situated always at the midpoint position between the two input sync signals. Pseudo sync signal generation means (101, 102) are triggered by the edge of the pulse waveform so that the pseudo sync signal of a phase different from that of the input sync signal is formed.

摘要： Estimation is carried out with high accuracy based on flow quality information in a situation where, although a set of links that may have a flow passing through is known, which of such links the flow passed through cannot be identified, such as multi-paths routing, load distribution routing, and the like. A device for estimating a quality-degraded location includes a flow quality information collecting section that collects communication quality of a flow of a network, a routing information collecting section that collects routing information of the network, a determining section for determining a quality-degraded flow and a quality-non-degraded flow based on the flow quality information to determine a link through which the flow passes from the routing information of the network, a non-degraded link elimination section that eliminates a link not configuring multi-paths as a non-degraded link without eliminating a link configuring multi-paths as a non-degraded link, for a link on a path of the flow, with respect to the quality-non-degraded flow, and a degraded link determining section for determining a degraded link from links not eliminated as the non-degraded links.
