Coordinated Multi-layer Network Operations White Paper

This white paper discusses the advancements and operational challenges associated with coordinated multi-layer network operations, particularly focusing on converged IP/Optical architectures. It outlines the necessity for service providers to adopt extensible network architectures that facilitate rapid scaling, simplify operations, and enhance sustainability. The paper details how converged hardware, such as 400G ZR, is being deployed by cloud and communications service providers (CSPs) and emphasizes the importance of multi-vendor interoperability. It identifies the operational inefficiencies that arise from disparate network management systems and advocates for a holistic, coordinated controller to optimize network performance. The document also highlights the complexities of CSP use cases beyond the initial 400G ZR deployment, including the need for advanced management of optical parameters and the integration of multi-layer control. Recommendations for CSPs are provided to navigate the evolving landscape of network management and operational efficiency.
