Frequently Asked Questions on OpenFlow and NETCONF
What is the limitation of OpenFlow?’
One drawback is that the currently specified match fields only apply to the packet header. Thus, a conventional OpenFlow does not enable deep packet inspection (DPI), which uses fields in the packet’s content to differentiate flows.
What is the purpose of OpenFlow?
The main purpose of OpenFlow is to forward packets to a single or more port.
What layer is OpenFlow?
Layer 2 of the OSI model is the OpenFlow that allows the SDN controller to interact directly with the forwarding plane of network devices.
What is the purpose of NETCONF?
NETCONF provides an interface to install, modify, and remove the configuration of network devices.
Which transport method is used by NETCONF?
NETCONF widely uses Secure Shell (SSH) as the transport layer between network devices. The port number 830 is a customizable option.
OpenFlow vs NETCONF
OpenFlow provides controllers of the network to determine the flow of network packets over a network of switches. Controllers are separate from switches. The Internet Engineering Task Force created and standardized the NETCONF network management protocol. NETCONF offers processes for installing, modifying, and deleting network device configurations.
