This CRD project is to develop a new, unified approach to auto-scaling the capacity of virtual network elements (VNEs), such as virtual routers and virtual switches, for the telco cloud. The telco cloud refers to cloud resources owned and managed by telecommunication companies. By shifting network functions and services to cloud, the telco cloud provides telco operators with an unprecedented opportunity for offering their customers better services at a lower cost. One of the core technologies supporting this shift is the agile management of virtual network elements, which is the ultimate goal of this CRD project. Existing efforts in auto-scaling VNEs consider the problem in isolation. In particular, workload prediction and performance modeling are focused on one application without considering the dependency between multiple applications. A better solution is to enforce multiple VNEs to adapt their capacity collaboratively. We thus need to not only address the diversity of VNEs, but also consider the dependency among VNEs. Using network of queues, copula analysis, machine learning, and experimental test, this CRD project will tackle the above problems. This project's output consists of a general solution that is applicable for adaptive capacity scaling of different types of VNEs. As such, this CRD project directly benefits Canadian telecommunication industry and will strengthen the bridge between university research and industry development. The research involved will advance our knowledge in the innovative application of cloud computing in the telecommunication industry. The technology developed can be directly applied in the cloud-based applications and offerings of our industry partner, Ericsson Canada, and highly-qualified personnel (HQP) trained in the project will be valuable assets in the Canadian IT sector.

该CRD项目旨在开发一种新的、统一的方法来为电信云自动扩展虚拟网元(VNE)的容量，例如虚拟路由器和虚拟交换机。电信云是指由电信公司拥有和管理的云资源。通过将网络功能和服务转移到云，电信云为电信运营商提供了前所未有的机会，以更低的成本为客户提供更好的服务。支持这一转变的核心技术之一是虚拟网元的敏捷管理，这也是本次CRD项目的最终目标。现有的自动伸缩虚拟企业的努力孤立地考虑了这个问题。特别是，工作负载预测和性能建模集中在一个应用程序上，而没有考虑多个应用程序之间的依赖关系。更好的解决方案是强制多个VNE协作调整其容量。因此，我们不仅需要解决虚拟企业的多样性问题，还需要考虑虚拟企业之间的依赖关系。使用排队网络、Copula分析、机器学习和实验测试，该CRD项目将解决上述问题。该项目的成果是一个通用的解决方案，适用于不同类型的VNE的自适应扩容。因此，这个CRD项目将直接惠及加拿大电信业，并将加强大学研究与行业发展之间的桥梁。所涉及的研究将增进我们对云计算在电信行业的创新应用的认识。开发的技术可以直接应用于我们的行业合作伙伴爱立信加拿大公司的基于云的应用程序和产品中，受过该项目培训的高素质人员(HQP)将成为加拿大IT行业的宝贵资产。
