To address the performance problems that many business critical applications are experiencing, network vendors and Network Service Providers (NSP) are reconsidering the integration of some form of application awareness in the way their networks forward user traffic. Their ultimate goal is to devise new network service models that are dedicated and customized to applications while efficiently using network resources. Even if this approach is not new and has been already followed with a mitigated success two decades ago, the emergence of software-Defined networking and network virtualization coupled with DPI (Deep Packet Inspection) pave the way for the investigation of new approaches/solutions towards application aware/driven networks. This is exactly the motivations of this work whose objective is to propose an Application Driven Network (ADN) that provides services to a specific type of applications, i.e. Dynamic Data Distribution Service (DDS) based applications. Considered as one of the leading connectivity standard for industrial IoT communications, focusing on DDS allows a fine-grained description of applications’ traffic and needs. With this information as input, the proposed ADN is able to provision network services that stick to application needs while using network resources efficiently. This paper sketches the general architecture of such ADN by describing its main components, their requirements as well as their algorithms. This solution has been implemented, prototyped and applied to a DDS based distributed interactive simulation application.

为了解决许多关键业务应用程序遇到的性能问题，网络供应商和网络服务提供商（NSP）正在重新考虑其网络转发用户流量的方式中某种形式的应用程序意识的集成。他们的最终目标是设计新的网络服务模型，这些模型专门针对应用程序而定制，同时有效地利用网络资源。即使这种方法不是新方法，并且在20年前已经取得了一定的成功，但软件定义的网络和网络虚拟化以及DPI（深度数据包检测）的出现为研究新方法/解决方案铺平了道路。应用感知/驱动网络。这正是这项工作的动机，其目的是提出一个应用程序驱动网络（ADN），该驱动程序为特定类型的应用程序提供服务，即基于动态数据分发服务（DDS）的应用程序。被视为工业物联网通信的领先连接标准之一，关注DDS可以对应用程序的流量和需求进行详细描述。利用此信息作为输入，建议的ADN能够提供符合应用程序需求的网络服务，同时有效地使用网络资源。本文通过描述ADN的主要组成部分，其要求以及其算法，来勾勒出这种ADN的一般体系结构。该解决方案已实现，原型化并应用于基于DDS的分布式交互式仿真应用程序。
