RFC 5381        Experience of Implementing NETCONF/SOAP     October 2008


1.  Introduction

1.1.  NETCONF over SOAP

   This document is not a product from the NETCONF WG but a report on
   the experience acquired by individual developers.

   SOAP (Simple Object Access Protocol) was specified in [RFC4743] as
   one of the transport protocols for NETCONF.  It is designed to use
   XML (eXtensible Markup Language) as its description language, which
   is a fundamental messaging technology for Web Services.  For this
   reason, SOAP is well suited to the NETCONF protocol and can be
   deployed widely.

   To develop a SOAP-based NETCONF client and server, several
   development tools are available as open-source software.  The authors
   developed a SOAP-based NETCONF client and server by using available
   development tools.  The SOAP-based NETCONF client was developed by
   utilizing Java APIs (Application Programming Interfaces) that are
   automatically generated from the XSD (XML Schema Definition) file and
   WSDL (Web Services Description Language) file obtained from [RFC4741]
   and [RFC4743], respectively.  The SOAP-based NETCONF client that the
   authors developed acts as an NMS (Network Management System).  The
   SOAP-based NETCONF server that the authors developed runs on network
   equipment and accepts NETCONF messages sent from the NETCONF client.

1.2.  Motivation

   The aim of this document is to describe why the authors believe SOAP
   is practical as a transport protocol for NETCONF when an NMS is
   developed.  When developing an NMS that uses SOAP as its transport
   protocol, development tools and procedures can be used according to
   the Web Services framework.  This document also describes the
   experience of implementing NETCONF over SOAP so that even those who
   have little knowledge of SOAP can start developing a SOAP-based
   NETCONF client and server.

   This document describes an alternative SOAP binding for NETCONF that
   does not interoperate with an RFC 4743 conformant implementation as
   it relies on cookies used on top of the persistent transport
   connections of HTTP.  This is provided for information purposes only
   based on the implementation experience of the authors.
