ABSTRACT:
The inventive packet transmitting apparatus transmits packets to receiving nodes located on a network, the packet containing at least one data block composed of at least one event sequence data and a timestamp added per a predetermined number of data blocks. In the packet transmitting apparatus, the packetizing section arranges the event sequence data into data blocks and adds thereto a timestamp so as to sequentially produce packets. The transmitting section sequentially transmits the packets. An error processing section operates when an error is detected during production of the packets for stopping transmission of a regular packet containing event sequence data and for generating and transmitting a special packet containing a message indicative of occurrence of the error. The error processing section includes a computation section that computes an input timing period of the data block based on a time of the timestamp, so that the error processing section operates when the computed input timing period deviates from a predetermined time period over an allowable range for detecting the error.
