Title: Bus optimizing method and communication node
Inventor: ARIMA YUKIO
IPC: H04L12/64
Filed: 2001-07-24
Abstract: PROBLEM TO BE SOLVED: To logically invalidate a port at a place to cut a loop by specifying such a place while considering signal transfer efficiency on a network when the loop is erroneously formed in a communication protocol to inhibit a loop- shaped connection. SOLUTION: When a signal cable is newly connected between communication nodes 0 and 1, the information of a port, with which the connection is detected, such as a loop test signal LT having the information of a transfer rate between ports, for example, is transmitted from the communication node 0, with which this signal cable connection is detected. A communication node 2, which receives such a loop test signal LT, applies information P(2,1) 62 of the present receiving port to the received loop test signal LT and repeats the loop test signal LT. The communication node 1 similarly applies information P(1,0) 63 of the receiving port to the loop test signal LT as well. Based on the port information stored like this, the communication node 0 specifies the place suitable for cutting the loop such as a port of the low transfer rate between ports, for example.
