uration of network devices. This has resulted in the creation of new standard protocol for network management known as NETCONF. NETCONF protocol gives the leverage to push, delete or manipulate configurations efficiently. It uses an Extensible Markup Language (XML) for configuration data and control messages. The protocol allows the device to expose a full application programming interface (API). A lot of vendor already support NETCONF to some extent and the list is growing with other vendors as well. Organizations are making their devices NETCONF understandable in their newer products & projects. It provides rich functions to manage configuration, operations & monitoring. NETCONF Properties Sessions use encrypted and efficient transport mechanism: XML content transported over SSH over TCP. Network Wide characteristics, a property to work parallel with different etwork element in the system. Messages use XML (Extensible Markup Language). Specially designed to provision & manage network elements within the Infrastructure. NETCONF uses a simple RPC-based mechanism. Designed for configuration.

YANG is used to model the operations and content layers of NETCONF YANG over NETCONF is a way to translate a device oriented language to a human friendly language. NETCONF is giving a standardization to communicate to a wide range of devices. YANG data modeling language describes syntax
