Cloud computing services are expected to grow annually 25% in the period 2012-2016 (IDC forecast). In fact this growth is five times bigger than the overall growth of IT industry, which indicates a major technological shift. Also, public cloud services constitute a significant part of enterprise spending and it is expected that this spending will reach $207 billion by 2016 (Gartners’s IT spending report). Public cloud computing is increasingly relying on WAN networking since the cloud resources can be located quite far from the users. Traditional internet has many limitations and in order to support cloud computing, a cloud support network should be significantly more agile and cost effective. Network as a Service (NaaS) is an important new networking paradigm that can help in achieving these cloud networking objectives. While NaaS has many definitions, in this project we consider NaaS as a service that is offered to users (mostly enterprise users) by a virtual network operator (located in a cloud) in order to manage and optimize WAN performance perceived by the user’s applications. In particular the focus is on latency, reliability and security. In general NaaS can be offered in combination with other cloud services or as a separate service. The importance of NaaS concept is validated by the fact that Cisco recently spent $1.2 billion to acquire Meraki - a leader in NaaS for small and medium companies. Note that while NaaS provides a framework that can facilitate WAN cloud networking it does not solve by itself the limitations of traditional Internet but rather allows creating better architectures and mechanisms build on top of the Internet that can address several issues. Therefore, apart optimization of NaaS for current Internet, it is also important to study which future Internet architectures are fitted best for cloud networking. In this project we propose to develop resource management mechanisms for WAN cloud networking that are based on different NaaS architectures including architectures build on top of future Internet and involving the SDN (Software Defined Networking) concept. These algorithms will be build based on an economic framework that can integrate many objectives of cloud networking. Apart giving solutions for particular NaaS architectures, the objective is to compare the performance to see which NaaS architectures and which future Internet options are most promising for cloud networking. We believe that the project results will be useful in two dimensions. First, the derived models and algorithms for NaaS can help virtual network operators to improve performance of cloud networking. Second, the study of the future Internet options in the context of cloud networking can be useful to decision makers that have a say in the future Internet developments.

云计算服务预计在 2012 年至 2016 年期间每年增长 25%（IDC 预测），事实上，这一增长速度是 IT 行业整体增长速度的五倍，这表明公共云服务正在发生重大技术转变。企业支出的重要组成部分，预计到 2016 年这一支出将达到 2070 亿美元（Gartner 的 IT 支出报告）由于云资源可能位于很远的地方，公共云计算越来越依赖 WAN 网络。传统互联网有很多限制，为了支持云计算，云支持网络应该更加敏捷和更具成本效益，网络即服务（NaaS）是一种重要的新网络范式，可以帮助实现这些云。虽然 NaaS 有许多定义，但在本项目中，我们将 NaaS 视为由虚拟网络运营商（位于云中）向用户（主要是企业用户）提供的服务，以便管理和优化用户感知的 WAN 性能。用户的应用程序。重点是延迟、可靠性和安全性。一般来说，NaaS 可以与其他云服务结合使用，也可以作为单独的服务提供。思科最近斥资 12 亿美元收购了行业领先者 Meraki，这一事实证实了 NaaS 概念的重要性。面向中小型公司的 NaaS 请注意，虽然 NaaS 提供了一个可以促进 WAN 云网络的框架，但它本身并不能解决传统互联网的局限性，而是允许在互联网之上创建更好的架构和机制，从而解决多个问题。 。所以，除了针对当前互联网进行NaaS优化之外，研究哪些未来互联网架构最适合云网络也很重要。 在这个项目中，我们建议开发基于不同 NaaS 架构的 WAN 网络云资源管理机制，包括构建在未来互联网之上并涉及 SDN（软件定义网络）概念的架构。这些算法将基于经济框架构建。除了为特定的 NaaS 架构提供解决方案之外，我们的目标是比较性能，以了解哪些 NaaS 架构和哪些未来的互联网选项最适合云网络。我们相信该项目的结果将是有用的。首先，NaaS 的衍生模型和算法可以帮助虚拟网络运营商提高云网络的性能；其次，对云网络背景下的未来互联网选项的研究可以对有发言权的决策者有用。在未来的互联网发展中。
