Question

In an SDN architecture, the network appears as _________ logical device to the applications.

Answer 1

Network management is facilitated by cloud computing which makes use of the SDN approach. This allows efficiency in network monitoring and performance. The issue of complexity and static nature of old-style network architecture and its decentralized is addressed by SDN. It also addresses the issues of present networks which require easy troubleshooting and more suppleness.  In SDN architecture, the network appears as a single logical device to the application

Answer 2

In SDN architecture, the network appears as single logical device to the applications

Explanation:

• Technology for 'software-defined networking (SDN)' is a network management methodology that allows dynamic, programmatically optimized network configuration to enhance network efficiency and controlling, preparing it more like 'cloud computing' than conventional network management.
• Network intelligence is centralized (logically) in 'software-based SDN controllers' which manage a 'global' view of the 'network' that appears as a 'single, logical transition' to applications and policy engines.
