摘要
在网络通信系统中,流量控制器是实现通信业务量管制的关键电路,用于监视和控制信元的传输速率。针对多个连接共享带宽的流量控制使用需求,在分析虚调度算法的基础上,结合FPGA并行计算的特点,提出一个基于FPGA的实时响应多通道并行流量控制IP核的实现方法 ,进行了仿真测试,给出了资源消耗和系统最高工作频率等结果。该IP核可应用于ATM和IP网络的流量控制。
In the network communication system, flow controller is the key circuit to realize the communication traffic management, used to monitor and control the cell transmission rate. In the light of the demand of multiply-connected flow controller sharing the same bandwidth, based on the analysis of the virtual scheduling algorithm, combined with the characteristics of the FPGA parallel computing, the paper puts forward the implementation method of a FPGA-based IP core with a real-time response and multi-channel parallel flow control. Having given the method a simulation test, the paper presents the results such as the system resource consumption and maximum working frequency, etc. The IP core can be applied to the ATM and IP network flow control.
