<span>The statement that IPv6 includes a native information security framework (IPsec) that provides both data and control packets is false.
</span>IPSec is a mandatory component for IPv6, and is used to natively protect IPv6 data <span>as it is sent over the network,. and not control packets.
</span>The IPv6 IPSec is a set of Internet standards that uses cryptographic security services to provide confidentiality ,data origin authentication and data integrity<span>

Programmers/Coders write the instructions for a Computer.
If a terminal emulation program is used and the devices should be reotely managed, then you should use the Telnet protocol. <span>Telnet is a simple, text-based network protocol that is used for accessing remote computers over TCP/IP networks like the Internet. </span>It allows the user access<span> to a text terminal and all its </span>applications<span> such as command-line for example. </span>
Answer and Explanation:
Messages flow across an SDN controller's:
Northbound APIs:
• Messages which help in read/write state of the network and developing flow tables within the
state management layer.
• Notifications for the state-change events.
• The interaction between the controller and network control applications is done through the
northbound interface.
• Network control applications send messages to the controller.
Southbound APIs:
• Messages which help for the up-to-date view of the network's state like message for the
attached link has gone up or down, new devices are joined the network, or indications of the
device is up or down.
• Controller's southbound interface is the communication among the controller and the controlled
devices. Controlled devices are the recipients of the messages sent form the controller.
