多业务驱动光网络中BoD业务关键技术研究与实现
|
摘要
当前光网络正经历着由传送网向业务网的转变,多业务驱动光网络成为未来光网络的发展趋势。光网络中数据业务的突发性、多样性和不可预测性等让业务提供模式面临着挑战,带宽按需分配BoD(Bandwidth on Demand)业务需求应运而生。自适应多业务光网络AMSON (Adaptive Multi-Service Optical Network)通过增加业务平面功能,丰富了ASON传送网体系架构。业务平面引入了新颖的业务解析、处理和实现方式,为BoD等富逻辑业务在多业务驱动光网络中的实现提供了一类创新性的解决方案。
本论文在业务平面理论和体系框架基础上,围绕BoD在业务平面的分布式解决方案,深入研究了BoD业务实现过程中的若干关键技术,如业务功能模型设计、算法描述、业务流程设计、业务逻辑复用等。同时,在项目组AMSON平台上对BoD业务进行了实际开发和部署实现,并进行了业务功能验证。试验结果表明,相对于ASON中基于管理平面和控制平面的BoD实现方式,AMSON中基于业务平面实现的BoD业务在全网阻塞率上有明显改善。
论文的主要内容与贡献如下：修改和完善了业务平面理论模型,使业务平面功能结构更加符合分布式和可扩性要求；分析了业务平面节点间的交互关系,提出面向业务控制模块的协作模型,并在BoD开发过程中进行了具体实现；设计并实现了业务平面BoD业务的开发部署方案,并在业务实现过程中归纳总结了可供其他业务形式复用的业务逻辑,提高了业务平面业务开发的灵活性和效率；搭建AMSON自适应多业务试验平台进行业务功能验证,平台的搭建为多业务驱动光网络的理论研究和业务实现打下良好的基础。
Right now, optical network is changing from transport network to service network, and multi-service-oriented network becomes the trend of optical networks. Data has been the dominating traffic in optical network. Burst, diversity and unpredictability of data challenge the way of carrying service in optical network. As a result, bandwidth on demand service is emerged. Adaptive Multi-Service Optical Network (AMSON for short), which introduces a creative Service Plane, has greatly enriched content of traditional ASON. Service Plane brings up a fresh way of service parsing and implementation, making the scheme of BoD implementation flexible and creative.
On the basis of Service Plane theory, this paper research implementation scheme of BoD service in Service Plane. Combined with the function model of Service Plane, this paper introduces key technologies of BoD service in detail, such as design of service function modules, implementation algorithm, service process, reuse of service logic modules and so on. BoD service is implemented in AMSON test bed, and result of the service is studied in this paper. The implementation result of BoD service in AMSON makes it clear that BoD service in Service Plane, compared with traditional way of BoD realization, improves the performance of optical network apparently.
Several achievements of this paper are as follows:Service Plane theory has been modified and improved, which makes Service Plane more flexible to be expanded and implemented in a distributed way; Interaction flow among different modules has been studied, and cooperation mode of Service Control Element (SCE) has been brought up and realized in BoD service; Implementation scheme of BoD service has been designed, and several service logic modules that can be reused in other services has been implemented; Test bed of AMSON has been built, and this test bed will be a good basis for further research of multi-service optical networks.
