Title:
COMMUNICATION NETWORK CONTROL METHOD
Document Type and Number:
Japanese Patent JP3160350
Kind Code:
B2
Abstract:
PURPOSE: To prevent a breakdown of an input signal, and to obtain an ideal throughput characteristic at the time of high load by interposing an interface device having a storage device between each transmitting/receiving terminal and each node device.
CONSTITUTION: Even when a collision occurs in either of between a transmitting/ receiving terminal 2 and an interface device 4, and between the interface device 4 and a node device 1, a signal is detected by both of a terminal side input port and a node side input port. In this case, when the signal of the node side input port is detected, a preamble is deleted by a 47-bit portion and written in a receive register 10. On the other hand, when the signal of the terminal side input port is detected, its signal is outputted to the node device 1 from a node side output port, and also, turned back and outputted to the transmitting/ receiving terminal 2, as well from a terminal side output port by controlling an output gate circuit 13. Thereafter, after the signal of the terminal side input port is gone, the signal written in the receive register 10 is outputted to the transmitting/receiving terminal 2.
