在介绍SLA和ASON产生背景的基础上,阐述了传统光网络不利于SLA实施的因素,进而分析A—SON有利于SLA实施的技术基础。最后,对SLA在ASON中实施的方案进行了设计,分析其参数的新特性,划分功能模块,并对各功能模块进行了详细讨论。
This paper firstly discusses SLA and ASON's birth background. Then, after given the shortcomings of applying SLA in traditional optical network, it analyzes the technical advantages of applying SLA in ASON. Finally, design of how to implement SLA in ASON is brought forward. New characters of SLA parameters in ASON are analyzed and function modules are presented with specific descriptions.
