Patent ID: 8848522

Claim:
A telecommunications system comprising: a plurality of node equipments that constitute a network to connect a plurality of user networks, and change setting information of a logical line between the user networks in accordance with a control request; a plurality of user terminals to transmit the setting information; and a server apparatus that receives a plurality of pieces of setting information from the plurality of user terminals and transmits control requests to the node equipments, wherein each of the user terminals includes: an input configured to input the setting information of the logical line between the user networks; and a transmission unit to transmit the setting information to the server apparatus, and wherein the server apparatus includes: a reception unit to receive the plurality of pieces of setting information from the plurality of user terminals a resource storage unit to store band information of a physical line connected to each of interfaces of the node equipments; a memory; and a processor configured to: classify the plurality of pieces of setting information received by the reception unit for each of the node equipments on a route of the logical line and each of the interfaces of the node equipments; store the classified plurality of pieces of setting information in the memory for each of the node equipments and each of the interfaces of the node equipments; judge whether the plurality of pieces of setting information are admissible or inadmissible based on the band information of the physical line and the plurality of pieces of setting information of the logical line with respect to the interface of each of the node equipments; and generate at least one control request to at least one node equipment among the plurality of node equipments based on the plurality of pieces of setting information of the logical line, which are judged to be admissible, wherein the reception unit receives the plurality of pieces of setting information transmitted from the plurality of user terminals simultaneously or within a certain time range, and wherein the processor is further configured to: collectively judge whether the plurality of pieces of setting information for the same node equipment and the same interface stored in the memory are admissible or inadmissible at the same time, the plurality of pieces of setting information being received from the plurality of user terminals; and store a judgment result in the memory.
