摘要
数据业务流量和信令呈现突发性增长趋势,对网络的容量和可靠性提出了新需求。LTE快速发展对核心网分组域提出了新的挑战,通过详细分析核心网分组域网络现状和存在的问题,论述了核心网云化演进的必要性,将NFV技术模式应用于电信网络的分组域核心网络,实现核心网云化,有益于网络弹性扩容、整体可靠性增强,更易于实现网络能力的共享与开放。
The data traffic and signaling showed unexpected growth, and the new demands were put forward for the capacity and reliability of the network. The rapid development of LTE brought new challenges to the core network packet. Through a detailed analysis of the core network packet domain network current situation and problems, the necessity of the evolution of the core network cloud was discussed. The NFV technical model was applied to the packet domain core network telecommunications network to achieve the core network virtualization which was helpful for network elastic expansion and overall reliability enhancing, and was easier to share and open the network capacity.
