摘要:
An example of a device comprises a storage which stores data which is input from outside and to which tracking information is added, a section which detects a first reading event of first data from the storage to which the tracking information is added, a section which detects, after the first reading event, a first writing event to part of character string data to the storage, a section which detects, after the first writing event, a second reading event of second data from the storage to which the tracking information is added, a section which detects, after the second reading event, a second writing event to part of the character string data to the storage, and a section which adds, when the first reading/writing event, second reading/writing event are detected, the tracking information to data to be written to the storage by the first and second writing event.
摘要:
A data transfer apparatus and a data transfer system are provided that can reduce the cost of installing communication equipment compatible with each of several dissimilar communication protocols in one exchange office and can reduce the cost of constructing the network. The data transfer apparatus includes a data reception device (110) that receives packets that comply with dissimilar communication protocols from upstream data transfer apparatuses (51, 52, and 53); a content data extraction device (120) that extracts content data included in the packets; a line selection information storage device (130) that stores the line selection information for selecting communication lines that comply with dissimilar communication protocols; a line selection device (140) that selects the communication line compatible with content data based on the line selection information; and a data transfer device (150) that transfers data to downstream data transfer apparatuses (61, 62, and 63) that are connected to the communication line that has been selected by the line selection device.
