摘要
SDN(软件定义网络)是一种新型网络架构,通过将网络设备控制平面与数据转发平面分离,实现了网络流量的灵活控制。宽带智能提速平台是中国电信遵循PCC/RACF架构提出的智能管道策略管控核心网元,分析了该平台和SDN基本架构的异同,并针对现有智能提速平台的不足,提出了智能提速平台依据SDN理论进一步演进的可行性方案。
SDN is a new network architecture, which achieves the flexible control of network traffic by separating the network device control plane and data forwarding plane. Broadband intelligent speedup platform was put forward by China Telecom which followed PCC/RACF architecture, and it was the core cell of the intelligent pipeline strategy to be in charge of the policy control. The similarities and differences between SDN architecture and broadband intelligent speedup architecture were analyzed, and in view of the shortcomings of the broadband intelligent speedup platform, the feasible evolution of broadband intelligent speedup platform based on SDN was put forward.
