Relationship between non-sdn list and sdn

You need to make a non-sdn list on sdn.

Non-sdn list refers to the list of countries that are not specially formulated.

SDN literally means software-defined network, which tries to get rid of the limitation of hardware on network architecture, so that the network can be modified like upgrading and installing software, and more apps can be quickly deployed on the network.

If the existing network is regarded as a mobile phone, the goal of SDN is to make an Android system in the network world, which can be installed and upgraded on mobile phones, and at the same time, more and more powerful mobile apps can be installed.

In the past 30 years, IP networks have been fully distributed and achieved outstanding results, which have solved various customer needs. Today, SDN is to meet the needs of future users better and faster. It's not that there is any demand that traditional methods can't do, but that SDN is faster, better and simpler.

The essence of SDN is network software, which improves the network programmability and reconstructs the network architecture, rather than new features or functions. SDN will realize various functional features better, faster and simpler than the original network architecture.
