基于超异构云的IMS软件体系结构：概念验证与实证分析
Hyper Heterogeneous Cloud-based IMS Software Architecture: A Proof-of-Concept and Empirical Analysis
摘要：
由3GPP定义的IP多媒体子系统（IMS）主要由电话供应商在供应商专用硬件上开发和部署。网络功能虚拟化（NFV）技术的最新进展为虚拟化硬件和电话功能弹性铺平了道路。因此，电信供应商已经开始接受云作为部署平台，通常选择特权虚拟化平台。运营商希望在其现有的IT云平台上部署电信功能。实现这种灵活性需要电信供应商采用允许在许多云平台甚至异构云平台上部署的软件架构。我们提出了一个分布式软件架构，使一个单一的软件版本部署在多个云平台，从而允许基于解决方案的部署。我们还提出了一个原型，我们开发的研究这种架构的特点。
英文摘要：
The IP Multimedia Subsystem (IMS) defined by the 3GPP has been mainly developed and deployed by telephony vendors on vendor-specific hardware. Recent advances in Network Function Virtualisation (NFV) technology paved the way for virtualized hardware and telephony function elasticity. As such, Telecom vendors have started to embrace the cloud as a deployment platform, usually selecting a privileged virtualization platform. Operators would like to deploy telecom functionality on their already existing IT cloud platforms. Achieving such flexibility would require the telecom vendors to adopt a software architecture allowing deployment on many cloud platforms or even heterogeneous cloud platforms. We propose a distributed software architecture enabling the deployment of a single software version on multiple cloud platforms thus allowing for a solution-based deployment. We also present a prototype we developed to study the characteristics of this architecture.
