Interoperability Test of NETCONF Capabilities

NETCONF is an important component of SDN (Software Defined Networking) architecture (as defined in RFC 7426) and network programmability and automation. ETF has defined the NETCONF (Network Configuration Protocol) standard in RFC 4741 in December 2006 and improved it in June 2011 in RFC 6241 (which is the currently active standard). NETCONF was created based on the requests of the network operators (defined in RFC 3535 in June 2002) for a standard protocol for the configuration of network devices. NETCONF defines the mechanisms of installing, manipulating, and deleting the network device configurations. NETCONF uses RPC messages, SSH for the transfer of messages between the server and the client ; it has its defined set of operations and it uses YANG for data modelling. NETCONF defines the initial basic set of operations and additional capabilities. Capabilities are additional functions of the NETCONF device (of client and server) that may but do not have to be implemented by the network devices. In this paper will be shown an overview of the capabilities of NETCONF protocol. The objective of this paper is to present the results of the interoperability lab where the support for NETCONF capabilities have been tested on router/switch (R/S) devices of major network equipment manufacturers. This paper describes the test environment and how the laboratory testing of the NETCONF capabilities of virtual network R/S devices was performed.
