ASON组网能力研究

Research on the networking capabilities of ASON

ASON是一种具有高灵活性和高可扩展性的基础光网络设施,它能在光层上直接提供服务,从而快速地满足用户的需求,并有效地解决网络的可扩展性、可管理性、快速配置用户带宽和端到端保护等问题。本文介绍了ASON的体系结构,包括三个平面、三种接口和三类连接,并详细分析了ASON的组网方式和组网结构,最后给出了朗讯公司的ASON组网方案。

Automatic switched optical network （ASON） is a set of optical infrastructure with high flexibility and extensibility, which can provide service at optical layer directly and can fulfill the requirements of subscribers, so it can solve some network problems perfectly, such as extensibility, manageability, subscriber bandwidth distribution and end-to-end network protection. We proposes the architecture of ASON wicth including three planes, three interfaces and three connections, then analyzes the networking mode and networking structure. In conclusion, we introduce the ASON networking scheme of Lucent.
