Abstract
In a packet switching network, in order to transmit a packet effectively, after transmission of a first packet from a source node to a destination node, a data for inhibiting a packet from being repeating to a specific trunk line from a node is set in a routing table associated with the node in accordance with a second packet received from the node. The associated routing table stores trunk lines for repeating in accordance with the destination node of the packet. The second packet represents occurrence of trouble on a transmission route for the first packet from the source node to the destination node. The transmission node includes the trunk line from the node. When the node has received a third packet directed to the destination node, the associated routing table is referred to determine a trunk line for repeating the third packet from trunk lines except for the specific trunk line in accordance with the destination node and the repeating inhibition data.
