                    draft-wangzheng-netconf-proxy-01

Abstract

   This document presents Network Configuration Protocol (NETCONF) Proxy
   through which NETCONF requests can be forwarded to a target host.  It
   would be useful when a client does not have direct network access to
   a target host.

1.  Introduction

   This document proposes a NETCONF Proxy mechanism.  The mechanism
   extends the NETCONF protocol [RFC6241] which provides a standard way
   to set up NETCONF session.  At its core, the mechanism defined here
   introduces a set of new operations which allow a client to forward
   NETCONF requests to a target host through an intermediary NETCONF
   proxy server, especially in case where client would otherwise not
   have direct network access to a target host.  The document also
   includes YANG data model which extend the model and RPCs defined
   within [RFC6241].

1.1.  Motivation

   NETCONF provide a RPC-based mechanism to facilitate communication
   between a client and a server.  The client can be a script or
   application typically running as part of a network manager.  The
   server is typically a network device [RFC6241].  However, the network
   manager may not have direct network access to the target network
   devices.  For example, some target network devices may locate in a
