vThe 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.
