基于用户数量的园区网络设计

为了便于因区网络的设计和管理，本文通过对美国FCC相关Internet带宽标准、IPTV流量测量与分析，以及经典排队理论等三种方法进行综合研究，提出了一种新的基于用户数量的因区网络设计方法．计算出网络或链路的用户的中值和下限值，并将此值与以太网链路类型直接映射，能快速计算园区网络所需的核心层、汇聚层和接入层带宽．

Campus Network Design based on the Number of User

In order to facilitate the design and management of campus networks, we study three methods： related American FCC Internet bandwidth standards, IPTV flow measurement and analysis, and classical queuing theory. After that a new design method which is based on the network user number is proposed. By calculating the mid-value and the lower value of network user number, and directly mapping the values to Ethernet link types, we can fast compute the bandwidths of core layer, convergence layer and access layer for this campus network.
