全球微波互操作接入(WiMAX)基站MAC层由于协议的复杂性、不完备性和系统大量的数据吞吐量,成为系统设计的瓶颈问题。该文结合WiMAX基站和网络处理器2个关键技术,提出一种基于多核网络处理器的WiMAX基站MAC层的设计方案,并给出软硬件架构,分析了MAC层的数据流程和控制流程,为WiMAX基站MAC层的设计提供了可行的方案。
The WiMAX base stations MAC layer is becoming the system design bottleneck issue due to its protocol complexity, incompleteness and the system large data throughput. This paper contains two key technologies of WiMAX base station and the network processor, proposes a multi-core network processors based WiMAX base stations MAC layer design, gives software and hardware architecture, analyzes the MAC layer data flow and control flow, and provides a feasible solution for the WiMAX base station MAC layer design.
