This paper presents an experimental evaluation of network protocols for control and management of optical networks and optical network equipment as seen in current trends. This paper presents the YANG data modeling language and its associated RESTCONF/NETCONF protocols. Later, it details multiple data models used in optical networks, such as IETF TEAS, ONF Transport API, OpenROADM, and OpenConfig. It also presents multiple protocols for telemetry (i.e., YANG PUSH, gRPC, and gNMI). Later, a zero-touch SDN controller architecture for multiple standard-defining organizations (SDOs) is presented, to support the usage of multiple protocols in a zero-touch optical network. Finally, the presented protocol implementations are experimentally evaluated and compared in terms of latency and overhead. The paper explores the use of these protocols (e.g., in research, demonstrations, and open-source optical networking projects) and provides results and recommendations for their integration in equipment and networks.

光SDN网络及设备控制监控协议实验评估【特邀教程】

本文对当前趋势中用于控制和管理光网络和光网络设备的网络协议进行了实验评估。本文介绍了 YANG 数据建模语言及其相关的 RESTCONF/NETCONF 协议。随后，它详细介绍了光网络中使用的多种数据模型，例如 IETF TEAS、ONF 传输 API、OpenROADM 和 OpenConfig。它还提供了多种遥测协议（即 YANG PUSH、gRPC 和 gNMI）。随后，提出了用于多个标准定义组织 (SDO) 的零接触 SDN 控制器架构，以支持在零接触光网络中使用多种协议。最后，在延迟和开销方面对所提出的协议实现进行了实验评估和比较。该论文探讨了这些协议的使用（例如，
