运营商网络云化重构思路浅析

Brief Analysis of Operator Network Cloud Reconfiguration

在当前大带宽、多连接、高精度业务对通信网络提出新的网络需求的促进下,运营商需以现网为基础,系统地进行新一代云化网络架构设计,并制定相应的演进策略。尽管基于SDN/NFV的运营商网络云化已基本成为共识,但由于硬件性能限制、标准化滞后及互操作的复杂性,网络的全面云化仍面临诸多挑战。基于运营商网络转型驱动因素,针对云化网络特点及其面临的风险进行具体分析,指出运营商网络云化重构需求,对未来网络云化架构提出可能的设计思路。

Promoted by the new network demands of present large bandwidth,multi-connection and highprecision services for communication network,operators need to systematically design a new generation of cloud network based on the existing network and formulate corresponding evolution strategies.Although the SDN/NFV-based operator network cloud has basically become a consensus,due to hardware performance constraints,lagging standardization and complexity of interoperability,the overall network cloud is still facing many challenges.Based on driving factor of operators’network transformation,this paper makes a concrete analysis of the characteristics and risks of cloud network,points out the needs of operators’network reconfiguration,and puts forward possible design ideas for future network cloud architecture.
