摘要:

随着移动网络用户期待5G网络的连接速度,服务提供商在没有大量财务投资的情况下满足连接需求方面面临挑战。网络功能虚拟化(NFV)作为一种新的方法学被引入,它提供了一种摆脱这一瓶颈的方法。NFV有望改变电信基础设施的核心结构,使其更具成本效益。在本文中,我们介绍了一个网络功能虚拟化框架,并讨论了它在移动网络中使用的挑战和要求。特别地,提出了虚拟环境中的NFV框架。此外,为了减少信令流量,实现更好的性能,本文提出了一个标准,捆绑在一个单一的物理设备或一组相邻的设备的虚拟化演进的分组核心的多个功能。分析表明,提出的分组可以减少70%的网络控制流量。

英文摘要:

As mobile network users look forward to the connectivity speeds of 5G networks, service providers are facing challenges in complying with connectivity demands without substantial financial investments. Network Function Virtualization (NFV) is introduced as a new methodology that offers a way out of this bottleneck. NFV is poised to change the core structure of telecommunications infrastructure to be more cost-efficient. In this paper, we introduce a Network Function Virtualization framework, and discuss the challenges and requirements of its use in mobile networks. In particular, an NFV framework in the virtual environment is proposed. Moreover, in order to reduce signaling traffic and achieve better performance, this paper proposes a criterion to bundle multiple functions of virtualized evolved packet-core in a single physical device or a group of adjacent devices. The analysis shows that the proposed grouping can reduce the network control traffic by 70 percent.
