The title of this RFC is "A YANG Data Model for Network Topologies."

RFC 8345 defines a YANG data model for representing network topologies, allowing for the description of both physical and logical network structures in a standardized format. YANG, a data modeling language used to model configuration and state data manipulated by NETCONF, is essential for simplifying the management of complex networks. This RFC provides a formal model for specifying how devices and connections are organized within a network, enabling network operators to visualize and manage their networks more effectively. The related RFC is RFC 6020, which introduces the YANG data modeling language, forming the foundation for models like those described in RFC 8345.

The primary goal of RFC 8345 is to enable standardized representations of network topologies to facilitate interoperability and network management across different platforms and devices. As networks become more complex, with numerous layers, network devices, and network connections, having a unified data model is crucial for maintaining consistency in network management systems. The related RFC is RFC 6241, which specifies NETCONF, the protocol that manages configuration data defined in YANG models, ensuring efficient communication between network devices and management systems.

RFC 8345 also addresses the challenges of modeling different types of topologies, such as Layer 2, Layer 3, and higher-level network abstractions. This flexibility allows for the representation of physical network topologies, such as the arrangement of routers and switches, as well as logical network topologies, such as virtual network overlays. By supporting multiple types of topologies, the data model facilitates a holistic view of network infrastructure. The related RFC is RFC 3031, which defines the Multiprotocol Label Switching (MPLS) architecture, an example of how logical topologies are used in network abstraction.

In addition to representing physical and logical topologies, RFC 8345 provides mechanisms for linking different layers of the network, such as connecting Layer 2 and Layer 3 topologies. This cross-layer connectivity ensures that network operators can trace paths across different layers, enabling more comprehensive troubleshooting and optimization. The related RFC is RFC 8349, which defines YANG models for Layer 3 configuration, showing how various layers can be integrated using standardized models.

The YANG data model described in RFC 8345 is intended to be extensible, allowing for the inclusion of future technologies and topologies as network architectures evolve. This extensibility is crucial in modern networks, which frequently incorporate new technologies such as Software-Defined Networking (SDN) and Network Function Virtualization (NFV). The related RFC is RFC 7426, which discusses the architecture of SDN and its impact on network control and management.

The model defined in RFC 8345 also supports the identification of individual nodes and their connections within a topology. This level of granularity allows network administrators to monitor and manage specific devices, ensuring optimal performance and rapid identification of faults. By using a standardized model for identifying nodes, RFC 8345 enhances the visibility and control network operators have over their infrastructure. The related RFC is RFC 8342, which defines a YANG data model for network configuration, providing additional mechanisms for managing nodes and connections.
https://tools.ietf.org/html/rfc8342

RFC 8345 addresses the challenge of visualizing and understanding complex topologies by defining a framework that can be integrated with network management systems. By modeling the relationships between devices and their interconnections, RFC 8345 helps simplify network monitoring and control. The related RFC is RFC 7276, which defines Framework for GMPLS and PCE Control of Wavelength Switched Optical Networks (WSON), another example of how network topologies can be modeled and managed in specific contexts.
https://tools.ietf.org/html/rfc7276

The YANG model in RFC 8345 is designed to interact with other YANG models for various network functions, including traffic engineering, virtualization, and routing. This modular approach ensures that network operators can build customized management systems based on specific operational requirements. The related RFC is RFC 8040, which defines RESTCONF, a protocol that works with YANG data models to provide a standardized interface for interacting with network devices and services.
https://tools.ietf.org/html/rfc8040

RFC 8345 is particularly useful in environments that require network automation, as the standardized model can be leveraged to automate network provisioning, configuration, and troubleshooting tasks. By using YANG data models, network operators can develop automation scripts and tools that simplify the management of large-scale networks. The related RFC is RFC 8174, which specifies terminology used in YANG models, clarifying how certain terms should be interpreted in the context of network automation.
https://tools.ietf.org/html/rfc8174

The RFC 8345 model is structured to allow for the integration of real-time monitoring data, providing a dynamic view of network topologies. This integration enables network operators to identify changes in topology, such as new devices being added or removed, and respond accordingly. The related RFC is RFC 7317, which defines a YANG model for system management, facilitating real-time monitoring and adjustments within network infrastructures.
https://tools.ietf.org/html/rfc7317

Another significant aspect of RFC 8345 is its role in supporting network scalability. As networks grow and evolve, the data model provides a scalable framework for managing increasingly complex topologies, ensuring that network management systems can keep pace with the expanding infrastructure. The related RFC is RFC 7938, which discusses the use of BGP in large-scale data center networks, showcasing how scalable network topologies can be efficiently managed.
https://tools.ietf.org/html/rfc7938

RFC 8345 also addresses the need for secure management of network topologies. By using standardized YANG models, network administrators can ensure that only authorized personnel have access to sensitive topology information. This security is critical in protecting network infrastructure from unauthorized changes or attacks. The related RFC is RFC 6536, which defines NETCONF access control models, providing security mechanisms for interacting with YANG-modeled network data.
https://tools.ietf.org/html/rfc6536

The integration of RFC 8345 with existing network standards is crucial for its adoption and effectiveness. By adhering to widely accepted protocols and models, the YANG topology model ensures interoperability between different network devices and management systems, making it a valuable tool for multi-vendor environments. The related RFC is RFC 8049, which defines a YANG model for MPLS-based services, illustrating how various network services can be modeled and managed using standardized frameworks.
https://tools.ietf.org/html/rfc8049

The model in RFC 8345 also supports the identification of link attributes, such as bandwidth and latency, allowing network operators to optimize performance by selecting the best paths for data transmission. This feature is particularly useful in traffic engineering, where understanding the characteristics of each link is critical for efficient network operation. The related RFC is RFC 8283, which defines YANG models for Segment Routing, providing tools for optimizing traffic flows in complex network environments.
https://tools.ietf.org/html/rfc8283

In multi-layer networks, where multiple topologies are interconnected, RFC 8345 provides mechanisms for linking different topologies to provide a unified view of the entire network. This capability is essential for understanding the relationships between physical and virtual network layers and for managing resources efficiently. The related RFC is RFC 8453, which describes the architecture for Layer 3 VPNs using BGP, an example of how multi-layer topologies can be integrated and managed.
https://tools.ietf.org/html/rfc8453

The YANG model for network topologies described in RFC 8345 is designed to be extensible, allowing for future updates as network technologies evolve. This extensibility ensures that the model can continue to support emerging technologies, such as 5G networks and Internet of Things (IoT) infrastructure. The related RFC is RFC 7540, which defines HTTP/2, demonstrating how extensible protocols can adapt to changing technology landscapes.
