山西广播电视台技术总控中心组播传送[1]至省网络公司有线总前端的十一个频道电视节目,是以二层核心交换机与总前端核心设备互联,传送IP流信号。因电视频道高清化带来数据量的增大、同时增加两路IPTV业务,需提高网络传输速度、提高网络安全性,我们选用高速度、高性能及高安全的三层交换机来替代二层交换机。本文对三层核心交换机的配置及使用进行探讨。
Shanxi Radio and Television Station Technology Control Center multicast to the provincial network company cable total front - end 11 channel television programs, is based on layer 2 core switch and the main front - end core equipment interconnection, Transmission IP stream signal. Because TV channel high - definition brings the increase of data volume, at the same time increase two IPTV services, need to improve the network transmission speed, improve network security, we choose high speed, Layer 3 switch with high performance and security is used to replace layer 2 switch.
