Cloud computing facilitates on-demand and scalable resource provisioning as services. This is implemented in a "pay-as-you go" manner, thus making resources available at all times from anywhere at affordable cost. This networking/service paradigm has gained considerable growth lately and is expected to be dominant in the future. Therefore, it is a rich area not only for academic research, but also an area of crucial importance for product/service development by Internet service/telecom providers. Cloud providers have to offer scalability along with reliable resources and services. To that end, Service Level Agreements (SLAs) state usage terms and penalties in case of performance violations. Provisioning of resources both at the computing as well as routing and service request scheduling levels should be performed in an "elastic" and scalable fashion. SLAs are constantly monitored with a goal to minimize performance violations while at the same time maximize user satisfaction and cloud provider revenue. Resource allocation and quality of service control and monitoring has been an active area of research in traditional data networks. However, the (geographically) distributed and diverse (in terms of service offered) nature of the "cloud" may be challenging to implement using traditional networking paradigms. Software Defined Networking (SDN) can contribute towards efficient, robust and readily reconfigurable cloud data centres. The goal of the proposal is to investigate present and evolving networking practices and their application for the advancement of next generation cloud computing systems and services.

云计算促进按需和可扩展的资源提供作为服务。这是以“付款方式”的方式实施的，因此可以以可承受的成本从任何地方提供资源。最近，这种网络/服务范式已经增长了可观的增长，并有望将来占主导地位。因此，这不仅是学术研究的丰富领域，而且是互联网服务/电信提供商对产品/服务开发至关重要的领域。 云提供商必须提供可扩展性以及可靠的资源和服务。为此，服务级协议（SLA）在绩效违规时说明条款和罚款。在计算以及路由和服务请求调度级别上的资源均应以“弹性”和可扩展的方式进行。不断监控SLA的目标，以最大程度地减少违规性能，同时最大程度地提高用户满意度和云提供商收入。 资源分配和服务控制和监控的质量一直是传统数据网络中研究的积极领域。但是，使用传统的网络范式实施“云”的（在提供的服务方面）（在提供的服务方面）（在提供的服务方面）的性质（在提供的服务方面）（在地理位置上的）性质（在地理位置上的）中，使用传统的网络范式（使用传统的传统网络范式实施）（就提供的服务而多样化），使用（就地理上的）分布和多样化（就提供的服务而言），使用传统的（在地理位置上）可能具有挑战性，但是， 软件定义的网络（SDN）可以有助于有效，健壮且易于重新配置的云数据中心。 该提案的目的是调查当前和不断发展的网络实践及其在下一代云计算系统和服务的发展中的应用。
