Repeater
First Claim
1. A repeater for organizing a communication network, the repeater comprising:
- a port section having a plurality of ports, the port section configured to transmit and receive frames;
a memory configured to store communication efficiency information and connection information for each of a plurality of communication nodes on the communication network; and
a repeat processor configuredto retrieve a destination address of a frame received by the port section,to select one of the plurality of the ports of the port section to transmit the received frame based on the destination address and the connection information stored in the memory, andto transmit the received frame from the selected port, whereinthe repeat processor is further configured to perform a distribute-transfer process when a plurality of frames having a same destination address is received by the port section, bydefining a plurality of communication paths to the same destination address by referencing the connection information stored in the memory,selecting one or more of the plurality of communication paths as a broadest path based on a preset communication efficiency parameter, the communication efficiency information stored in the memory, and the connection information stored in the memory,selecting one communication path as the broadest path having a high communication efficiency when more than one of the plurality of communication paths are selected as the broadest path,distributing one of the plurality of frames having the same destination address and having a highest communication speed to a port in connection with the broadest path, whereinthe communication efficiency information indicates a communication efficiency of each of the plurality of ports of the repeater and of each of a plurality of other ports associated with the communication nodes, and whereinthe connection information indicates connections among the communication nodes on the communication network.

Abstract
A repeater efficiently transfers frames addressed to the same destination address when the frames are received at the same time by a plurality of ports, by performing a distribute-transfer process, when a difference between a size of each of the frames received by a normal port and an average size of those frames is within a preset range for all the frames, or an actual-measured communication speed of each of two ring ports is greater than a threshold. The distribute-transfer process distributes and transmits the frames to two communication paths from the two ring ports after receiving the frames at the two normal ports. The highest actual-measured communication speed of a ring port among other ring ports of the repeaters is considered as a communication efficiency parameter for selecting a broadest communication path for transmitting the frame. The frame(s) having the highest communication speed is/are distributed to the ring port connected to the broadest path.
