PTN中LAG技术研究与实现

Research and implementation of LAG technology in PTN

为了满足用户对通信速率和质量的需求,文中提出了一种LAG链路聚合功能的实现方案。该功能能够在提供更大带宽同时提供冗余保护且保护倒换时延相对较小。文中论述了LAG技术的原理及典型应用场景,提出逻辑设计思路和物理实现方案。实验结果证明该方案在PTN交换设备中实现了链路聚合功能,并能有效进行负载均衡。

In order to meet users’requirements for communication rate and quality,this paper proposes a scheme to realize LAG link aggregation.This function can provide more bandwidth while providing redundant protection and relatively small protection switching delay.In this paper,the principle of LAG technology and typical application scene are discussed,and the logic design idea and physical implementation scheme are put forward.Experimental results show that this scheme can realize the link aggregation function in PTN switching equipment,and can effectively carry out load balancing.
