The NETCONF protocol is a modern building block for device management automation, offering a unified approach to network configuration, rather than a device-specific methodology. To equipment vendors, NETCONF is a way to standardize the management interface of network elements. To service providers, NETCONF is a way to optimize the administrative workflow, by moving management intelligence out of the device under management, and consolidating this management into higher-level applications.
This paper reviews the business cost of major outages. It also details some of the reasons that network architecture has become so complex, discusses current approaches to the problem and finally presents NETCONF as a powerful building block solution to the network management problem.
The key issues involved in developing on-device network management systems for carrier-grade enterprise and operator networks are the same for any other networked resource, only with more complexity and built-in restrictions due to the limited space and processing capabilities inherent to these types of devices.
This whitepaper describes how NETCONF and YANG can help drastically simplify network configuration management. The IETF has recently standardized the NETCONF configuration management protocol and is currently in the process of standardizing a NETCONF-oriented data modeling language called YANG. These two new technologies promise to drastically simplify network configuration management.
Network management systems must adapt to meet the requirements of next generation networks. For example, a user interfaces may need to be refreshed with a state-of-the-art Web interface or support for the NETCONF protocol may be required to help customers deploy scalable networks. Adding functionality and integrating with existing applications and data stores has multiple trade-offs in terms of development time and system efficacy.
