As Internet-of-Things (IoT) technology is attaching an unprecedented number of devices to the edge of the network, manual provisioning of on-demand bandwidth and resources to meet Quality-of-Service (QoS) for these technologies is not a feasible task. Instead, they are better managed at the edge of the network using compute resources within the virtual environment, also known as Network Function Virtualization (NFV). IT virtualization along with cloud-based services is transforming the industry by providing unprecedented flexibility and agility. Instead of owning their own equipment, customers can now rent or lease compute services from various providers such as Google, Amazon, Microsoft and others. Software Defined Networking (SDN) is a programmable paradigm that provides network services to these hosted virtual environments. Currently many network functions (e.g., firewalls, security appliances and load balancers) use hardware devices that are located outside of the virtual environment; however, it would be natural to use NFV to deploy these hardware functions, which is known as Network Function Virtualization (NFV). This is a key emerging area that allows unprecedented flexibility and agility in deploying or migrating new network services and functions on-demand and based on application and/or traffic profiling. The main goals of this proposal are to investigate and develop methods, algorithms and techniques to provide scalable, energy efficient network infrastructure for the next generation Internet services based on virtualization for IoT technologies. Our specific focus is to innovate and develop methods on the following topics: 1) Investigate methods on how to decompose and execute network functions that are traditionally implemented in dedicated hardware appliances across several software elements or Virtual Machines (VMs) dynamic network functions. Investigate methods to allocate network and cloud resources for IoT NFV deployment; Develop mechanisms to ensure reliable services and service level guarantees for such NFV based service architectures; 2) Develop methods to characterize workloads, detect traffic and service anomalies and 3) Data center network (DCN) architectures: Investigate methods and architectures to connect and guarantee network link and bandwidth resources in DCNs to efficiently deploy NFV based services; Canada has always been on the forefront of telecommunications and data networks technology. This research will contribute to future network architectures with efficient deployment of network services using latest virtualization technologies. The research will also train HQP in the critical area of future network architectures and services.

随着图像（IoT）技术将空前数量的设备附加到网络边缘，手动提供按需带宽和资源以满足这些技术的服务质量（QoS）并不是一项可行的任务。取而代之的是，它们在虚拟环境中使用计算资源（也称为网络函数虚拟化（NFV））在网络边缘进行更好的管理。它通过提供前所未有的灵活性和敏捷性来虚拟化以及基于云的服务来改变行业。客户现在可以从Google，Amazon，Microsoft等各种提供商那里租用或租用自己的设备，而是可以租用或租赁各种提供商的计算服务。软件定义的网络（SDN）是可编程范式，可为这些托管虚拟环境提供网络服务。当前，许多网络功能（例如，防火墙，安全设备和负载平衡器）使用位于虚拟环境之外的硬件设备；但是，使用NFV部署这些硬件功能是很自然的，这被称为网络函数虚拟化（NFV）。这是一个关键的新兴领域，可以在按需以及基于应用程序和/或流量配置文件的情况下部署或迁移新的网络服务和功能时进行前所未有的灵活性和敏捷性。该提案的主要目标是调查和开发方法，算法和技术，以根据物联网技术的虚拟化为下一代Internet服务提供可扩展的，节能的网络基础架构。我们的具体重点是对以下主题进行创新和开发方法：1）研究如何分解和执行网络函数的方法，这些方法传统上在多个软件元素或虚拟机（VMS）动态网络函数的专用硬件设备中实现。调查为IoT NFV部署分配网络和云资源的方法；开发机制，以确保此类基于NFV的服务体系结构的可靠服务和服务水平保证； 2）开发表征工作负载，检测流量和服务异常的方法以及3）数据中心网络（DCN）架构：调查DCN中连接和保证网络链接和带宽资源的方法和体系结构，以有效地部署基于NFV的服务；加拿大一直处于电信和数据网络技术的最前沿。这项研究将使用最新的虚拟化技术有效地部署网络服务，从而为未来的网络体系结构做出贡献。该研究还将在未来网络体系结构和服务的关键领域培训HQP。
