Abstract

PURPOSE:To decentralize the transmittal confirmation processing to be concentrated onto a sender with frame multiple access by defining a multiple access frame, transferring data among nodes sequentially in the relay system, applying the prescribed processing of normal reception to the said frame in each node and allowing the sender node to confirm the reception of the multiple access frame of a prescribed form. CONSTITUTION:When a node 11 among nodes 11-1n applies frame multiple access, its own address is set to a sender node address part 102 in the frame, a node address of the node 12 being the succeeding destination node is set to a reception start node address part 103, and its own node address is set to a final reception node address part 104 respectively. Then a multiple access frame in which a data part 105 is added and the kind of frame multiple access is set to a control part 101 is generated and sent to the node 12 through a transmission line 21. Thus, the multiple address frame sent from the sender node 11 once is confirmed sequentially in each node and circulated up to the sender node and the load of the reply frame processing is not concentrated onto the sender node 11.

When node 11 of In performs frame broadcasting, node 11 sets its own node address in the source node address field 102 in the frame and the next node of the forwarding destination in the reception start node address B103. A certain node 12
, and the final receiving node address part 1
A broadcast frame is created by setting its own node address in 04, adding a data section 105, and setting a broadcast frame type in the control section 101, and transmitting it to the node 12 via the transmission path 21. The node 12 receives the broadcast frame when the reception start node address field 103 of the broadcast frame matches its own node address, and if the reception is normal, the reception start node address field 103 is sent as a delivery confirmation to the sender.
is set to the node address of node 13, which is the forwarding destination node, and the own node address is set to the final receiving node address 1104, and the other parts are exactly the same as the broadcast frame transferred from node 11. sends a message frame to node 1 via transmission path 22.
Send to 3. Repeat the same operation on each node,
The node 11 receives a broadcast frame in which the source node address 8102 is set to its own node address, and the reception start node address field 103 sets the own node address and the last receiving node address one node address earlier to vtiKB. At this point, the frame broadcast operation ends normally. If an abnormality is detected during inter-node transfer during the transfer, the abnormality detection node returns an abnormality report frame containing the final receiving node address and reception start node address information to the source node.

発信元ノードでは異常報告フレーム内の受信開始ノード
アドレスからフレーム同報動作を再開するか、異常処理
