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，特别是这些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，从而解决在小型和农村社区部署宽带服务的经济可行性问题，同时确保公共安全应用程序可以在这种环境中发挥作用。 我们的目标是，我们的工作将作为一个生活实验室，探索农村城市的智能和互联应用，并作为这些较小社区的示范部署。现有的宽带网络不太适合满足公共安全应用的需求。 部署专用的公共安全网络在经济上是不可行的，并且现有的宽带网络不能为公共安全应用提供必要的保护/优先级，因此存在公共安全通信将在最需要的时候被干扰的风险。 我们认为，开放访问市政软件定义网络（SDN），更广泛的市政软件定义基础设施（SDI）的出现，是一个关键的推动力，以解决这些问题，并彻底改变公共安全应用。为了实现这一愿景，我们提出了一个合作研究计划，称为SafeEdge。 我们建议：（i）开发与智能和互联小城市需求相关的下一代应用程序示例。我们的具体重点将是公共安全应用，即，机构公共安全应用以及公民启用的公共安全应用。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与其他应用和服务混合的可行性，我们还将探索非公共安全应用，例如，动态远程课堂访问、动态访问司法职能（远程提审、远程访问法律的代表）等。（ii）探索在开放服务市政软件定义的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、机制和基元。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，并提供与公共安全应用程序相关的资源的适当优先级。我们还将开发一个灵活的网络接入框架，以实现下一代（公共安全）应用的动态特性。(iii)使用部署在ID的阿蒙市的市政软件定义基础设施，实现一个示例农村开放服务生态系统，并形成物理宽带基础设施，我们将在此基础上进行试点研究。
