摘要

全球移动网络运营商不得不花费数十亿美元将自己的网络升级到最新的移动电话高速数据无线通信标准(例如长期演进,LTE)。这与每用户平均收入的下降形成对比,并威胁到:(1)他们的盈利能力;(2)对新标准的快速适应。因此,研究能够降低移动网络资本支出(capex)和运营支出(opex)的新机制至关重要。在一个共同的基础设施上启用多个移动网络运营商就是这样一种机制。软件定义网络可以克服这一问题,并提出了一种基于探索OpenFlow (OF)作为移动网络虚拟化架构的解决方案。我们在技术经济分析中研究了基于该OF解决方案的两种网络场景:(场景1)软件定义的非共享网络和(场景2)虚拟化的共享网络,并将其与当前情况进行比较。通过这样做,本文提供了移动网络运营商通过软件定义网络(SDN)和网络共享可以实现的相对成本节约的见解。技术经济分析表明,第一聚合阶段和第二聚合阶段网络基础设施的SDN和虚拟化将大大降低移动网络运营商的资本支出成本。因此,通过使用OpenFlow实现移动网络基础设施虚拟化可能成为解决成本上升和盈利能力下降问题的解决方案之一。然而,我们没有考虑到对运营支出的直接影响,以及网络共享可能对运营商差异化能力产生不利影响的间接影响。

Techno-economic Analysis of Software Defined Networking as Architecture for the Virtualization of a Mobile Network
Worldwide mobile network operators have to spend billions to upgrade their own network to the latest standards for wireless communication of high-speed data for mobile phones (e.g. Long Term Evolution, LTE). This is in contrast with the decline in average revenue per user and threatens: (1) their profitability and (2) the fast adaptation of new standards. Investigating new mechanisms that can decrease the capital expenditures (capex) and operational expenditures (opex) of a mobile network is therefore essential. Enabling multiple mobile network operators on a common infrastructure is one such mechanism. Software defined networks can overcome this problem and a solution based on exploring OpenFlow (OF) as architecture for mobile network virtualization has been proposed. We investigate two network scenarios based on this OF solution in a techno-economic analysis: (scenario 1) software-defined, non-shared networks and (scenario 2) virtualized, shared networks and compare it against the current situation. By doing so, this paper provides insights on the relative cost savings that a mobile network operator can reach through Software Defined Networking (SDN) and network sharing. The techno-economic analysis indicates that SDN and virtualization of the first aggregation stage and second aggregation stage network infrastructure leads to substantial capex cost reductions for the mobile network operator. As a consequence, mobile network infrastructure virtualization through the use of OpenFlow could be one of the problem solvers to tackle the issue of rising costs and decreasing profitability. Still, we did not take into account the direct effect on operational expenditures and the indirect effect that network sharing can adversely affect the ability of the operators to differentiate themselves.
