摘要： An optical receiving circuit 1 is composed of a preamplifier circuit 2, an output differential amplifier 3 and a mean value holding circuit 4. The optical receiving circuit 1 is connected to a photodetector 5 for receiving an input optical signal and outputting current. For the preamplifier circuit 2, a transimpedance type circuit may also be used. The preamplifier circuit 2 comprises a feedback resistor 21 and a resistor for detecting output voltage 22, the transimpedance gain is 55 dB &OHgr; and 3 dB bandwidth when the photodetector 5 the capacity of which is 0.2 pF is connected to its output is 8 GHz. The output differential amplifier 3 discriminates and regenerates data by regulating reference voltage Vref between the high level and the low level of the amplitude of an input signal. The mean value holding circuit 4 includes a sample-hold circuit 41 and capacity 42 for holding the mean value of voltage output from the preamplifier circuit 2. As a CR time constant based upon the capacity 42 and the resistor for detection 22 is 1 ns., the mean value level of a received signal can be detected in approximately one byte of the data of 10 Gb/s. The sample-hold circuit 41 samples the detected mean value level according to a sampling pulse from an external device and holds it. The output of the sample-hold circuit 41 is used for the reference voltage of the differential amplifier 3.

摘要： In a communications network where cross-connect nodes are organized according to geographic domains, a domain connectivity table indicates intra-domain connectivity of each domain and a domain routing table indicates a route specifying those nodes whose intra-domain connectivity is indicated in the domain connectivity table. Each node uses its domain routing table to establish a path between edge nodes. In another embodiment, the domain routing table indicates routes containing no intra-domain virtual link that terminates at an edge node and no consecutively concatenated intra-domain virtual links. A backbone routing table indicates inter-domain routes and unreachability indications between border nodes of each domain and border nodes of every other domain. The inter-domain routes contain at least one of the inter-domain physical links but contain no consecutively concatenated intra-domain virtual links.

摘要： A configuration storage unit (110) stores the constituent element identification information of each constituent element, in association with the type information indicating the type of the constituent element, the constituent element identification information of another constituent element related to the constituent element, and the type information of the another constituent element. For each piece of the type information, a rule storage unit (120) stores the type information of another constituent element, which is influenced when failures occur in the constituent element corresponding to the type information, in association with influence information indicating a content of the influence. An availability model generation unit (130) generates an availability prediction model for an information processing system, on the basis of the information stored in the configuration storage unit (110) and the information stored in the rule storage unit (120).
