This project addresses the unique challenges associated with rural smart and connected cities and specifically the public safety needs of such communities. Our open access/multi-service approach will allow municipalities to deploy a variety of services, thus addressing concerns about the economic feasibility of deploying broadband services in small and rural communities, while at the same time ensuring that public safety applications can function in this environment. Our aim is that our work would serve both as a living lab in which to explore smart and connected applications for rural cities and also to serve as a model deployment for these smaller communities.Existing broadband networks are not well suited to satisfy the needs of public safety applications. It is economically infeasible to deploy dedicated public safety networks and existing broadband networks cannot provide the necessary protection/priority to public safety applications, thus running the risk that public safety communication will be interfered with precisely when it is most needed. We argue that the emergence of open access municipal software defined networks (SDNs), and more broadly municipal software defined infrastructures (SDIs), is a key enabler to address these concerns and to revolutionize public safety applications. Towards realizing this vision, we propose a collaborative research program, called SafeEdge. We propose to: (i) Develop example next generation applications associated with the needs of a smart and connected small city. Our specific focus will be on public safety applications, i.e., institutional public safety applications as well as citizen-enabled public safety applications. However, to evaluate the multi-service nature of our environment, and the feasibility of mixing public safety applications with other applications and services, we will also explore non-public safety applications, e.g., dynamic remote classroom access, dynamic access to judicial functions, (remote arraignment, remote access to legal representation) etc. (ii) Explore the network abstractions, mechanisms and primitives required to support future public safety applications within the context of an open service municipal software defined infrastructure. We will specifically develop resource management mechanisms and algorithmsto enable dynamic creation and/or modification of virtual network instances, and to provide appropriate prioritization of resources associated with public safety applications. We will also develop a flexible network access framework to enable the dynamic nature of next generation (public safety) applications. (iii) Use the municipal software defined infrastructure deployed in the City of Ammon, ID, to realize an example rural open service ecosystem and to form the physical broadband infrastructure on which we will be piloting our research.

该项目解决了与农村智能和互联城市相关的独特挑战，特别是此类社区的公共安全需求。我们的开放接入/多服务方法将允许市政当局部署各种服务，从而解决对在小型和农村社区部署宽带服务的经济可行性的担忧，同时确保公共安全应用程序可以在这种环境中运行。 我们的目标是，我们的工作既可以作为一个生活实验室，探索农村城市的智能和互联应用，也可以作为这些较小社区的模型部署。现有的宽带网络不太适合满足公众的需求安全应用。 部署专用的公共安全网络在经济上不可行，并且现有的宽带网络无法为公共安全应用提供必要的保护/优先级，从而存在公共安全通信在最需要的时候受到干扰的风险。 我们认为，开放接入市政软件定义网络（SDN）以及更广泛的市政软件定义基础设施（SDI）的出现是解决这些问题和彻底改变公共安全应用的关键推动因素。为了实现这一愿景，我们提出了一个名为 SafeEdge 的合作研究计划。 我们建议： (i) 开发与智能互联小城市需求相关的下一代应用示例。我们的具体重点将是公共安全应用程序，即机构公共安全应用程序以及公民支持的公共安全应用程序。然而，为了评估我们环境的多服务性质，以及将公共安全应用程序与其他应用程序和服务混合的可行性，我们还将探索非公共安全应用程序，例如动态远程教室访问、动态访问司法功能、 （远程提审、远程访问法律代表）等。 (ii) 探索在开放服务市政软件定义基础设施的背景下支持未来公共安全应用所需的网络抽象、机制和原语。我们将专门开发资源管理机制和算法，以实现虚拟网络实例的动态创建和/或修改，并为与公共安全应用程序相关的资源提供适当的优先级。我们还将开发一个灵活的网络访问框架，以实现下一代（公共安全）应用程序的动态特性。 (iii) 使用爱达荷州阿蒙市部署的市政软件定义基础设施来实现农村开放服务生态系统示例，并形成我们将在其上试点研究的物理宽带基础设施。
