随着云计算、大数据等新技术的蓬勃发展以及通信基础设施的不断升级,国内三大运营商均提出以智能牵引网络转型,构建集中控制,灵活编排的云网基础架构的发展战略。PCEP 作为一种广泛应用于 SDN架构的路径计算协议,往往应用于解决复杂网络环境跨层、跨域约束路径的计算。从探讨 PCEP 在云网融合场景应用的角度出发,提出了一种基于PCEP的流量端到端保障方案,可实现在本地IP环境下,面向连接的网络通信及端到端业务保障,有助于提升运营商对网络的实时感知、敏捷响应、智能分析等能力,满足通信资源可全局调度、能力可全面开放、架构可灵活调整的运维管理需求。
With the booming development of new technologies such as cloud computing
big data and the continuous upgrading of communication infrastructure
the major domestic ISPs have proposed the development strategy of building a centralized control and flexible cloud network infrastructure under the trend of intelligent-traction network transformation.As a path calculation protocol widely used in the existing SDN architecture
PCEP protocol was often used to solve the problem of cross-layer and cross-domain path computing under complex network environment.The application of PCEP protocol in cloud-network convergence scenario was discussed and an end-to-end traffic guarantee scheme was introduced based on PCEP protocol which could ensure the connection-oriented network communication and make end-to-end service guarantee in native IP environment.It helps to improve the operators' ability of real-time perception
agile response and intelligent analysis of the network and meets the operation and maintenance management requirements such as global scheduling of communication resources
comprehensive opening of capabilities and flexible architecture.
