Abstract

See full text

In an ATM communication control device, a cell transmission timing via a virtual channel is determined based on peak rate instructed in a received predetermined ATM cell, such as a received RM cell. Upon determining the transmission timing, a next transmission time for a virtual channel is stored in a CAM, and when a counter value agrees with the stored transmission time, the virtual channel corresponding to an address storing the agreed transmission time is determined as a virtual channel for transmission. The CAM may be replaced by a combination of comparators and a normal storage device.
