先进的光分组交换(OPS)技术与多协议标签交换(MPLS)技术强大控制能力的结合,产生了一种灵活紧凑的IP/DWDM集成模型基于标签的光分组交换(LOPS)技术。它充分发挥了OPS的灵活性和光交叉连接(OXC)的大容量优势,是未来核心光交换网络的理想解决方案。文章从OPS节点结构开始,分析了LOPS的网络结构和功能模型,简述了MPLS的控制能力。 The combination of advanced optical packet switching (OPS) technology and the robust control of Multiprotocol Label Switching (MPLS) technology has resulted in a flexible, compact label-based optical packet switching (LOPS) technology for IP / DWDM integrated models. It gives full play to the OPS flexibility and large capacity of optical cross-connect (OXC), and is the ideal solution for future core optical switching networks. Starting from the structure of OPS nodes, this paper analyzes the network structure and function model of LOPS, and briefly describes the control ability of MPLS.
