Charter of Working Group:

Configuration of networks of devices has become a critical requirement 
for operators in today's highly interconnected networks. Large and small 
operators alike have developed their own mechanisms or have used vendor 
specific mechanisms to transfer configuration data to and from a device 
and to examine device state information which may impact the 
configuration. Each of these mechanisms may be different in various 
aspects, such as session establishment, user authentication, 
configuration data exchange, and error responses.

The NETCONF protocol has the following characteristics:

- Provides retrieval mechanisms which can differentiate between 
configuration data and non-configuration data
- Is extensible enough so that vendors can provide access to all 
configuration data on the device using a single protocol
- Has a programmatic interface (avoids screen scraping and formatting-
related changes between releases)
- Uses an XML-based data representation, that can be easily manipulated 
using non-specialized XML manipulation tools.
- Supports integration with existing user authentication methods
- Supports integration with existing configuration database systems
- Supports multiple (e.g. candidate and running) data-stores to optimize 
configuration preparation and activation
- Supports network wide configuration transactions (with features such 
as locking and rollback capability)
- Runs over a secure transport; SSH is mandatory to implement while TLS, 
BEEP, and SOAP are optional transports.
- Provides support for asynchronous notifications.
- Supports an Access Control Model and a YANG module for configuring the 
Access Control parameters.
- Supports a YANG module for System Notifications

The NETCONF protocol is data modeling language independent, but YANG is 
the recommended NETCONF modeling language, which introduces advanced 
language features for configuration management.

In the current phase of NETCONF's incremental development the workgroup 
will focus on following items:

1. Advance NETCONF over TLS to be in-line with NETCONF 1.1 (i.e., update 
RFC 5539).

2. Based on the implementation, deployment experience and 
interoperability testing, the WG will produce a NETCONF status report. 
The result may be clarifications for RFC6241 and RFC6242 and addressing  
any reported errata.
