Abstract
A LAN-WAN-LAN communication method and apparatus for performing communication between a LAN on a transmitting side and a LAN on a receiving side via a wide area network within limits of an allocated band includes a demultiplexer/multiplexer unit for demultiplexing data, which has been received from the LAN on the transmitting side, into data constituting the smallest units of information and transmitting this data via a plurality of lines. Then, data, which is sent to the receiving side via each line, is multiplexed on the receiving side and the multiplexed data is sent to the LAN on the receiving side. A traffic monitoring unit is provided for monitoring traffic between LANS. A band is obtained, which is required for communication between LANs based upon the traffic. Communication between LANs is performed by increasing, decreasing or maintaining the number of lines, which are used in communication between LANS, based upon the obtained band.
