SD-WAN在广电网络中的应用研究

Application Research of SD-WAN in Broadcast & TV Network

“大禹治水”证明堵是不行的,疏导才是上策。各地广电网络公司对于网络优化还停留在几年前流控的思路,去抑制大流量应用和大流量用户,这往往会引起用户投诉,现在新的思路是网内自建缓存(Cache)和引入大互联网公司的CDN,但对于高端客户需要的游戏、总部专线和SAAS云,如何解决一直是一个难题。探讨如何使用SD-WAN技术去帮助广电网络解决这些问题,留住高端客户,提高ARPU值,以及如何选择SD-WAN产品。

Broadcast & TV Network companies around the country still stay in the idea of flow control a few years ago to suppress large-volume applications and users, which often leads to user complaints. Now the new idea is to build cache in the network and introduce CDN of big Internet companies. But for high-end customers, they need the game, headquarters line and SAAS cloud, how to solve the problem has always been a difficult problem. This paper discusses how to use SD-WAN technology to help Broadcast & TV Network companies solve these problems, retain high-end customers, improve ARPU value, and choose SD-WAN products.
