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.

当今网络的管理通常需要一群投入大量时间和精力的运营商。软件定义的网络（SDN）已被证明是简化网络管理的有希望的范式。但是，SDN中的管理任务需要使用约束的网络资源：开关内存和CPU以及开关控制器网络带宽。鉴于这些资源限制，网络运营商在启动网络管理任务时可能必须推理资源使用情况。该项目旨在探索软件定义网络管理的资源管理空间。具体而言，它将检查虚拟化资源池的设计，这些池提供（几乎）无限资源（内存，CPU和Switch）的抽象，同时动态地适应了这些网络管理任务的资源需求。这种方法的优点是，在实例化网络管理任务时，网络运营商不必为资源使用情况进行推理。该研究将产生资源管理算法，改进的资源使用设计以及虚拟资源池的系统实施。网络运营商对网络基础架构进行了数十亿美元的投资，但很少考虑这些基础架构的可见性和控制。该项目可能导致ISP，企业和云中掌握更好，更可靠且更具资源效率的网络基础结构。这些努力最终将通过实现商业，社会和科学进步来产生更广泛的社会影响。该提案将使代表性不足的团体和本科生参加研究的机会，并可能导致技术转移到主要的云提供商和ISP。
