Industry 4.0 represents a new industrial revolution that will dramatically change the landscape in many sectors, including manufacturing and logistics. Robotics, machine intelligence, and new forms of connectivity are key ingredients of this paradigm. 5G mobile networks are expected to play a crucial role, supporting a lower cost per transported bit in air and a lower latency compared with 4G. 5G radio ensures different performance levels in very heterogeneous coverage situations, including a mix of indoor and outdoor contexts. Mobile network evolution requires new transport networks to address the new challenging requirements: increasing transmission capacity, compatibility with latency-critical applications, significantly reduced cost with respect to conventional metro network segments, lower energy consumption, and, in some cases, switching capabilities. Optical communications and networking will play a key role in these new transport scenarios, where tailored transmission techniques and network architectures are needed. This paper discusses the requirements and challenges that Industry 4.0 scenarios pose to optical communications and networking architectures. Performance of optical transmission schemes, tailored to support these new radio access networks, are detailed and benchmarked. A network test bed, focused on transport for vertical use cases, is described. Experimental results demonstrate the compliance of the proposed optical transport network with a latency-critical cloud robotics application, which presents industry-grade connectivity needs.

工业4.0的光传输[受邀]

工业4.0代表着一场新的工业革命,它将极大地改变包括制造业和物流业在内的许多领域的格局。机器人技术,机器智能和新型连接形式是该范例的关键要素。预计5G移动网络将发挥关键作用,与4G相比,支持每空中传输的比特成本更低,等待时间更短。5G无线电可在非常不同的覆盖情况下(包括室内和室外环境的混合)确保不同的性能水平。移动网络的发展需要新的传输网络来满足新的挑战性要求:增加传输容量,与延迟关键型应用程序兼容,相对于传统城域网网段显着降低成本,降低能耗,并且在某些情况下,交换能力。光通信和网络将在这些新的传输方案中扮演关键角色,在这些新方案中,需要量身定制的传输技术和网络体系结构。本文讨论了工业4.0场景对光通信和网络体系结构提出的要求和挑战。为支持这些新的无线接入网而量身定制的光传输方案的性能已详细列出并进行了基准测试。描述了一个专注于垂直用例传输的网络测试平台。实验结果表明,提出的光传输网络符合对延迟至关重要的云机器人应用程序的要求,这满足了工业级连接需求。需要量身定制的传输技术和网络架构的地方。本文讨论了工业4.0场景对光通信和网络体系结构提出的要求和挑战。为支持这些新的无线接入网而量身定制的光传输方案的性能已详细列出并进行了基准测试。描述了一个专注于垂直用例传输的网络测试平台。实验结果表明,提出的光传输网络符合对延迟至关重要的云机器人应用程序的要求,这满足了工业级连接需求。需要量身定制的传输技术和网络架构的地方。本文讨论了工业4.0场景对光通信和网络体系结构提出的要求和挑战。为支持这些新的无线接入网而量身定制的光传输方案的性能已详细列出并进行了基准测试。描述了一个专注于垂直用例传输的网络测试平台。实验结果表明,提出的光传输网络符合对延迟至关重要的云机器人应用程序的要求,这满足了工业级连接需求。为支持这些新的无线接入网而量身定制的详细和基准测试。描述了一个专注于垂直用例传输的网络测试平台。实验结果表明,提出的光传输网络符合对延迟至关重要的云机器人应用程序的要求,这满足了工业级连接需求。为支持这些新的无线接入网而量身定制的详细和基准测试。描述了一个专注于垂直用例传输的网络测试平台。实验结果表明,提出的光传输网络符合对延迟至关重要的云机器人应用程序的要求,这满足了工业级连接需求。
