The Application And Implementation Of TMS Traffic Management Technology In CDN System

With the rapid development of mobile Internet, CDN for the development of mobile Internet business has become more important, speed and stability of the network has become a key factor in retaining user, Tencent, Alibaba, Baidu and other major Internet companies have developed their own CDN system to resolve user pain points because of the rapid development of the mobile Internet has brought the network, such as delay, network congestion, cross-regional information synchronization slow and so on.Large audience site or customer service website in Chinese specific network environment is inseparable from CDN and user scheduling. The CDN and user scheduling involves intelligent DNS resolution and user positions.TMS traffic management system is part of a global CDN traffic scheduling dispatch and is a DNS-based global load balancing service. Support transparently route traffic to the public network scheduling CDN (including third-party CDN) or any server, implementation is fast and reliable flow through the CDN (or server) between distributed scheduling.In this paper, the rapid development of CDN networks at home and abroad as the background, a domestic carrier based on open source simulation test prototype CDN joint declaration of the project, describes the role of the DNS service to the core of the TMS traffic scheduling system in the global CDN traffic scheduling The first chapter introduces the status quo rise CDN technology development at home and abroad; The second chapter introduces the key technology TMS traffic scheduling systems and single node CDN system applied; third chapter introduces the single-node CDN system architecture and functionality, including content library node section from the underlying code perspective on the introduction; chapter describes the architecture and policy features TMS traffic scheduling system, and implementation of various functions; the last chapter demonstrates part of the system, showing the use of the system, configuration and scheduling effects.Through the system functional testing and performance testing, TMS user traffic scheduling system can quickly respond to user requests for precise scheduling, greatly enhance the user Internet experience, with good market prospects and value.
