摘要

随着业务的发展,在光传送网(OTN)中需要基于客户侧业务的灵活连接调度、快速连接响应以及线路侧资源的高效调度。本文在引入 OTN 细粒度技术的基础上,提出了面向服务的多层资源调度架构和算法。具体来说,我们提出了一种服务感知方案,使 OTN 能够更好地匹配服务需求。在集中分布式协作架构的基础上,我们扩展了路径计算要素通信协议(PCEP),以实现更高效的连接分配。我们进一步设计了一种基于多层协作的资源调度策略和算法,以针对不同优先级的服务执行差异化调度。通过提出的机制和算法,在技术上可以实现用户侧业务的精确匹配、连接和资源的灵活调度以及高效的业务响应,推动 OTN 业务供应从传统的固定点对点连接向灵活的面向服务的光网络(SOON)连接演进。

Multi-layer resource scheduling architecture and algorithm for a service-oriented optical network based on a fine grain OTN
With the development of service, there are demands for flexible connection scheduling based on customer-side services, fast connection response, and efficient scheduling of line-side resources in an optical transport network (OTN). This article proposes a service-oriented multi-layer resource scheduling architecture and algorithm based on the introduction of OTN fine grain technology. Specifically, we propose a service awareness scheme that enables OTNs to better match service requirements. Based on a centralized distributed collaborative architecture, we extend a path computation element communication protocol (PCEP) to achieve more efficient connection distribution. We further design a resource scheduling strategy and an algorithm based on multi-layer collaboration to perform differentiated scheduling for services with different priorities. Through the mechanisms and algorithms proposed, it is technically feasible to achieve precise matching of customer-side services, flexible scheduling of connections and resources, and efficient service response, and promote the evolution of the OTN service supply from traditional fixed point-to-point connections to flexible service-oriented optical network (SOON) connections.

期刊介绍: The scope of the Journal includes advances in the state-of-the-art of optical networking science, technology, and engineering. Both theoretical contributions (including new techniques, concepts, analyses, and economic studies) and practical contributions (including optical networking experiments, prototypes, and new applications) are encouraged. Subareas of interest include the architecture and design of optical networks, optical network survivability and security, software-defined optical networking, elastic optical networks, data and control plane advances, network management related innovation, and optical access networks. Enabling technologies and their applications are suitable topics only if the results are shown to directly impact optical networking beyond simple point-to-point networks.
