Abstract: PROBLEM TO BE SOLVED: To decrease the number of datagrams as little as possible and to increase data to be packed in respective datagrams as much as possible by sampling a data record out of a sequence order through a means for packing the data record into the datagram at the time of allocating the data record to the datagram. SOLUTION: A data access device 102 dispatches data to be transmitted from a storage device 101 to a data record forming device 103. The data record forming device 103 divides the data into data records in various sizes and sends them to a data packing device 104. The data packing device 104 allocates maximum non-allocated data records in a usable space to the first datagram while concentrating them to the first datagram for allocating the data records when the usable space in the first datagram is equal to or layer than that for the minimum data record not allocated to the datagram yet.

Abstract: In an asynchronous message queuing network, a data processing method of finding a lost message includes the steps of: sending a first message from an originating data processing unit to an intermediate data processing unit, the message including an indication that the message is traceable; sending a tracer message from an originating data processing unit to an intermediate data processing unit, the tracer message identifying the first message as a lost message which the originating data processing unit would like to find; at the intermediate data processing unit, upon receiving the tracer message, checking to determine whether the first message exists within the intermediate data processing unit, and sending a reply message back to the originating unit if the first message is found within the intermediate data processing unit; and at the intermediate data processing unit, if the first message is not found within the intermediate data processing unit, determining whether the first message has passed through the intermediate data processing unit, and if the first message has passed through the intermediate data processing unit, determining a neighboring data processing unit which received the first message from the intermediate data processing unit and forwarding the tracer message to the neighboring data processing unit.

Abstract: Messages sent over a network may include a flag to indicate that they are traceable. When a message is received at a data processing unit the flag is checked and if the message is traceable then information identifying the message and the next data processing unit that it was forwarded to are stored. A tracer message may be sent by the data processing unit which generated the traceable message. When this is received by another data processing unit, it determines if the message identified by the tracer message is present in the processing unit and notifies the originating unit if it is, if not it determines if it has information stored about the identified original message. If it does the tracer message is forwarded to the data processing unit that the original traceable message was forwarded to, based on the stored information. The network may be an asynchronous message queuing network.

Abstract: A data communications apparatus connected to a network through which datagrams flow from the data communications apparatus to at least one other data communications apparatus also connected to the network, the apparatus having: a means for receiving data which is to be transmitted over the network, such data being broken up into data records; and a means for packing the data records into datagrams for transmission over the network, including a means for assigning data records to datagrams; wherein the means for packing takes the data records out of sequential order when assigning data records to datagrams.
