摘要: 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.

摘要: Methods for controlling a data packet flow through a switch having first, second and third stage switch modules. Each switch module has a number of data inputs, a number of data outputs, and a data packet buffer. The data outputs of the first stage switch modules are connected to data inputs of the second stage switch modules, and data outputs of the second stage switch modules are connected to the data inputs of the third stage switch modules. A data packet received at one of the first stage switch modules is forwarded to a specific data output of one of the third stage switch modules. A method for controlling a data packet flow comprises: A storing credit information associated to each of the second stage switch modules indicating a number of free data packet buffer locations in the respective second stage switch module; selecting one of the second stage switch modules in dependence on the credit information; forwarding the received data packet from the first stage switch module to the selected second stage switch module; forwarding the received data packet from the selected second stage switch module to the respective third stage switch module, from which the received data packet is to be sent; after sending the data packet from the respective third stage switch module, delivering a credit information about the freed data packet buffer location from the third stage switch module to the second stage switch module, wherein the respective second stage switch module is chosen by a credit return strategy.
