Connectionless communication system
First Claim
1. A communication system for use with a network for communicating between a terminal on a first side and a terminal on a second side, comprising:
- a local network, connected to a plurality of terminals on said first side, to transmit fixed length cells from one of said plurality of terminals on said first side to said terminal on said second side via a virtual connection in said local network;
buffer capacity monitoring means in said terminal on said second side for monitoring a capacity of a buffer receiving said fixed-length cells and for outputting an alarm signal at the time of detecting a congestion state of said capacity of said buffer;
congestion state alerting means in said terminal on said second side, responsive to said alarm signal from said buffer capacity monitoring means, for setting a congestion bit on said fixed-length cells to be transmitted to said one terminal on said first side and for outputting said fixed-length cells with said set congestion bit to said one terminal on said first side; and
traffic transmission control means in said one terminal on said first side, responsive to said fixed-length cells from said congestion state alerting means in said terminal on said second side, for controlling a transmission of said fixed-length cells to be transmitted to said terminal on said second side in the other of said plurality of terminals on said first side.

Abstract
A communication system for use with a network for transmitting fixed-length cells from a transmitting terminal via a virtual connection in the network to a receiving terminal. The communication system includes a converting device, connected to the transmitting terminal or the receiving terminal, for performing a bi-directional conversion between a variable-length packet and the fixed-length cells, the transmitting terminal or the receiving terminal outputting the variable-length packet, a buffer capacity monitoring device in the receiving terminal for monitoring a capacity of a buffer in the receiving terminal receiving the fixed-length cells and for outputting an alarm signal at the time of detecting a congestion state of the capacity of the buffer, a congestion state alerting device in the receiving terminal responsive to the alarm signal from the buffer capacity monitoring device for outputting an alert signal to the transmitting terminal, and a traffic transmission control device in the transmitting terminal responsive to the alert signal from the congestion state alerting device in the receiving terminal for controlling a transmission of the fixed-length cells to the receiving terminal.
