达县分公司广电城域网出口终端带宽优化设计

Output Bandwidth Optimization about MAN in the Broadcasting and Television Administration of Daxian

对达县分公司广电城域网现有业务和防火墙QoS配置进行了分析,认为部分客户反映的网速不理想除了总出口带宽有限之外,总带宽没有充分利用是主要因素。结合智能流控技术中的分层CAR和动态CAR两个关键技术,在不增加任何硬件成本和出口带宽的前提下,提出了对现有业务IP规划和防火墙QoS优化配置,实现不同业务出口终端带宽相对公平分配,解决了带宽资源闲置问题。

Current business and QoS configuration about firewall are analyzed in MAN at the Broadcasting and Television Administration of Daxian, for the complaint from some customers about bandwidths badness, that the total bandwidth is under utilization is regarded. Combined with two key techniques（ layered CAR and dynamic CAR） intelligent flow control, and under condition of not adding any hardware and output bandwidth, current IP business replanning and configuration about QoS optimization is proposed in order to implement fair allocation output bandwidth for different business, and finally free resource bandwidth is resolved.
