Question: 13


Which of the following sequences best describes the process of moving to SDN based self-regulated networking?


  1. action-based networking -> static networking -> adaptive networking -> autonomous networking

  2. static networking -> action-based networking -> autonomous networking -> adaptive networking

  3. static networking -> action-based networking -> adaptive networking > autonomous networking

  4. action-based networking -> static networking -> autonomous networking -> adaptive networking


Answer: C


Explanation:


Nokia NSP is a platform that enables management, control and automation of IP/Optical networks. It supports various levels of network automation, from static networking to autonomous networking.


The process of moving to SDN based self-regulated networking involves four stages:


â Static networking: The network is manually configured and operated by human operators. There is no automation or intelligence involved.


â Action-based networking: The network is partially automated by using predefined actions or scripts that are triggered by events or commands. There is still human intervention required for complex tasks or exceptions.


â Adaptive networking: The network is dynamically automated by using policies, analytics and machine learning that can adjust the network behavior based on changing conditions and objectives. There is minimal human intervention required for oversight and validation.


â Autonomous networking: The network is fully automated by using artificial intelligence and closed-loop feedback that can optimize the network performance and reliability without any human involvement. The network can self-heal, self-optimize and self-protect.
