基于动态调控的接入控制器板间通信策略

为解决用户群体不断增加、数据量日益增大而造成的网络AC(接入控制器)单个板卡处理能力不足的问题,采用了一种AC板间通信方案。介绍了AC板间通信的原理,并深入分析了影响板间通信性能的关键因素,提出了一种适合AC板间通信的方法,并介绍了编程实现过程。通过对AC动态调控,关联调控网络AC各个板卡中的模块,将业务运行在相应板卡,以达到各个数据流的负载均衡;并兼顾系统中的各个板卡的性能和运行状况,以达到提高AC系统的整体性能、降低成本的目的。

An access controller multi-board communication strategy based on dynamic regulation

In order to improve the processing capacity of single boards in network Access Controllers (AC) for accommodating the constantly growing number of users and daily increasing amount of network data, this paper adopts a multi-board communication strategy, introduces its basic principle and analyzes in-depth the key factors affecting its performances. Furthermore it proposes a method appropriate for multi-board communication and the programming. By the dynamic regulation of the AC to associate the modules in every board, it operates the traffics in the corresponding board so as to ensure the load balance of every data flow. Taking into account the performances and operation of all the boards, it improves the overall performances of the AC system and reduces the cost.
