Abstract
Efficient use of an ATM transmission path becomes possible by multiplexing, into a bandwidth in the bandwidth-assured individual VP, a plurality of users whose traffic volumes are beyond a predetermined value. Installing a bandwidth-unassured common VP for low traffic users makes it possible to switch from the common VP to the individual VP or vice versa under the following conditions. (1) When the user traffic volume, monitored at fixed intervals during the communications through an individual VP, drops below a predetermined threshold value, the individual VP is switched to a common VP. (2) When the user traffic volume, monitored at fixed intervals during the communications through a common VP, exceeds a predetermined threshold value, the common VP is switched to an individual VP. (3) In addition to condition (2), when bandwidth shortage takes place in common VPs, the common VPs of heavy traffic users are switched to individual VPs.
