The Design and Implementation of WiMAX Base Station MAC Based on Intel Network Processor

The paper provides WiMAX BS (base station) MAC design, implementation discussion with performance analysis based on Intel IXP2350, which include MAC design key issues discussion, base station usage model and architecture, MAC hardware and software high level design and relevant performance analysis. Especially, the WiMAX base station is user-specific, and WiMAX MAC software is one of the most important base station components, so we discuss in details about MAC data plane software design and performance pre-analysis based on IXP2350 micro engines. Current hardware GE forwarding test and data plane software pre-analysis shows that the design scheme can meet WiMAX base station system performance requirement.
