The System Design and Performance Analysis of WiMAX Base Station MAC Based on Intel Network Processor

This paper provides WiMAX BS (base station) MAC system design and performance analysis based on Intel IXP2350, which includes MAC design key issues discussion, base station usage model and architecture, MAC hardware and software high level design with 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 system performance requirement.
