摘要
基于IP和光网络的现状和联合组网需求,针对IPoverWDM和IP+OTN/WDM两种组网模型,从流量协同规划、告警联动、保护协调3个方面提出IP+OTN/WDM联合组网技术的优化策略。优化策略将优化IP+OTN/WDM的联合组网方案,提高全网资源利用率,并最终降低网络建设成本和运维成本。
In this paper, we analyze the requirements for optimizing a combined IP and optical network. There are different models for such a combined network, including IP over dense wavelength division multiplexing （WDM） and IP＋OTN/WDM. We describe optimization strategies for the IP＋OTN/WDM model; in particular, we describe traffic synergic planning, alarm linkage, and protection coordination. In optimizing the IP＋OTN/ WDM combined network, we seek to increase efficiency of all network resources and network capex and opex.
