초록 ▼

An interface device having a storage function is interposed between each of connections between node devices and transmit/receive stations. When input signals from one transmit/receive station and one node device are received at almost the same time, the input signal from the node device is temporarily stored in the interface device. The input signal stored in the interface device is read therefrom and output after the input signal from the transmit/receive station ends.

대표청구항 ▼

A method of controlling a communications network which includes a plurality of node devices connected so that a tree-like hierarchical structure is formed, each of said node devices having a single high-order direction port and a plurality of low-order direction ports, the communications network including a plurality of transmit/receive stations each being connected to one of the node devices via an interface device, each of the transmit/receive stations having an input port and an output port connected to the node devices via the interface and transmitting a signal when there is no signal at the input port, a highest-order node device out of the node devices in the communications network broadcasting a first-arrival signal which is received by said highest-order node device, said first-arrival signal being one of signals which are transmitted by some of transmit/receive stations at almost the same time, signals other than the first-arrival signal being discarded, said method comprising the steps of: (a) storing, in a buffer provided in said interface device and arranged so as to receive a signal via said one of the node devices, a first input signal received by said interface device from said one of the node devices approximately concurrently with a second input signal received by said interface device from one of the plurality of transmit/receive stations; and (b) transmitting the first input signal received from said one of the node devices and stored in said buffer in the step (a), to a destination transmit/receive station after the second input signal from said one of the plurality of transmit/receive stations is no longer received; wherein the buffer comprises a FIFO memory and further comprising the steps of: (c) storing said first input signal received from said one of the node devices into a first input of the FIFO memory provided in the interface device, said FIFO memory having a second input parallel to the first input; (d) writing a space signal into the second input of the FIFO after the first input signal ends; (e) transmitting a collision presence signal from the interface device to said one of the transmit/receive stations which transmits the second input signal when the first input and the second input signal arrive at the interface device at almost the same time; and (f) transmitting the first input signal written into the first FIFO input to said one of the plurality of transmit/receive stations which transmits the second input signal in response to receipt of the collision presence signal.
