NeTS: Small: A Virtualized Network Resource Pool for Software-Defined Network Management

当今网络的管理通常需要大量的运营商投入大量的时间和精力。软件定义网络（SDN）已被证明是简化网络管理的有前途的范例。然而，SDN中的管理任务需要使用受限的网络资源：交换机内存和CPU，以及交换机控制器网络带宽。由于这些资源的限制，网络运营商可能不得不在启动网络管理任务时考虑资源的使用情况。本项目旨在探索软件定义网络管理的资源管理空间。具体来说，它将研究虚拟化资源池的设计，这些资源池提供（几乎）无限资源（内存、CPU和交换机）的抽象，同时动态地适应这些网络管理任务的资源需求。该方法具有以下优点：网络运营商在实例化网络管理任务时不必推理资源使用。网络运营商在网络基础设施上投入了数十亿美元的投资，但很少考虑这些基础设施的可见性和控制性。该项目可以在ISP、企业和云中实现更好的管理、更可靠和更高效的网络基础设施。这些努力最终将通过促进商业、社会和科学进步而产生更广泛的社会影响。该提案将为代表性不足的群体和本科生提供参与研究的机会，并可能导致向主要云提供商和ISP的技术转让。

Management of today's networks usually requires an army of operators who devote tremendous time and energy. Software-defined networking (SDN) has been shown to be a promising paradigm for simplifying network management. However, management tasks in SDNs require the use of constrained network resources: switch memory and CPU, and the switch-controller network bandwidth. Given these resource constraints, network operators may have to reason about resource usage when initiating network management tasks.This project seeks to explore the space of resource management for software-defined network management. Specifically, it will examine the design of virtualized resource pools that provide the abstraction of (nearly) infinite resources (memory, CPU and switch), while dynamically adapting to the resource needs of these network management tasks. This approach has the advantage that network operators do not have to reason about resource usage when instantiating network management tasks. The research will yield resource management algorithms, improved resource usage designs, and systems implementations for virtualized resource pools.Network operators make billion-dollar investments in network infrastructures, but put little thought into visibility and control of these infrastructures. This project can lead to better-managed, more reliable, and more resource-efficient network infrastructures in ISPs, enterprises and clouds. These efforts eventually will have broader societal impact by enabling commercial, social, and scientific advances. The proposal will give underrepresented groups and undergraduates opportunities to participate in research and will likely result in technology transfer to major cloud providers and ISPs.
