摘要
传送功能与控制功能相结合,阻碍了传统光网络智能化的实现。通过引入独立的控制平面,使智能光网络的实现成为可能。为此,介绍了自动交换光网络的概念;阐述了引入控制平面的优势及控制平面的基本构成。最后从网络接口、功能模块及信令协议的角度,讨论了自动交换光网络(Automatically Switched Optical Network,简称ASON)控制平面的核心技术。
Because the transport function and the control function are combined together, the implementation of intelligence of traditional optical networks is blocked.With independent control plane,the implementation of intelligence optical networks is possible.The concept of ASON is given, and the advantages of ASON and the architecture for control plane are introduced in this paper.The technologies of control plane from network interface ,functional model and signalling protocol are discussed finally.
