Abstract
The present invention provides an apparatus and system for buffering data in a communication network with an arranged priority which enables traffic shaping. A cell buffer unit () is arranged with a plurality of queues () configured to store PDUs on-chip and off-chip. There are associated queues both on-chip and off-chip for each priority queue. A cell buffer controller () forwards PDUs to a predetermined priority queue and manages the transfer of PDUs off-chip when a priority queue on-chip is fully occupied. The controller () also manages the transfer of PDUs from the off-chip queue when the on-chip priority queue becomes less than fully occupied.
