Abstract: The present invention discloses a scalable flow-control mechanism. In accordance with the present invention, there is provided a switching device for transporting packets of data, the packets being received at the switching device based on flow-control information, the device comprising a memory for storing the packets, a credit counter coupled to the memory for counting a credit number of packets departing from the memory, and a scheduler unit coupled to the credit counter for deriving the flow-control information in response to the credit number. Moreover, a switching apparatus and a method for generating flow-control information is disclosed.

Abstract: The present invention discloses a memory sharing mechanism based on priority elevation. In accordance with the present invention, there is provided an apparatus and method for transporting packets of data in a communication device, wherein each packet is assigned one of several priorities and received based on memory state information. The method comprises the steps of storing the received packets in a memory and modifying the assigned priority of any of the packets causing congestion within the memory.
