Patent ID: 8340092

Claim:
A switching system for transferring data, the data including destination information specifying a destination, the switching system comprising: a data collection device of a plurality of data collection devices in which first data is collected, the first data being subject to specific processing among the data; and a plurality of switching devices directly or indirectly connected to the data collection device, wherein at least one of the plurality of switching devices comprises: a determination module that determines whether received data is the first data or is second data, the second data not being subject to the specific processing; and a marking module that puts a first marking on the received data determined to be the first data, wherein each of the plurality of switching devices comprises: a storage that stores first path information and second path information indicating a transfer destination of the received data; and a transferring processor that executes a first transfer process for sending the received data to the data collection device, based on the first path information, when the received data has the first marking, and a second transfer process that sends the received data to the specified destination, based on the second path information, when the received data does not have the first marking, wherein the first data is data which is possibly abnormal, wherein the specific process is process of determining whether or not the first data is abnormal, wherein the data collection device comprises an inspection module that inspects the gathered first data and determines whether or not the first data is abnormal, wherein the data collection device removes the first marking from the first data determined not to be abnormal and sends the first data determined not to be abnormal to any one of the plurality of switching devices, and wherein the data collection device removes the first marking from the first data determined not to be abnormal and also puts a second marking on the first data determined not to be abnormal, the second marking indicating that data having the second marking is not abnormal; wherein the first path information includes a plurality of types of path information to transfer data to each of the data collection devices; wherein a plurality of types of the first marking corresponding to the plurality of types of path information included in the first path information are used, wherein the transferring processor, among the plurality of types of path information, references path information corresponding to the first marking type on the received data to execute the first process.
