Q

Explain why in traditional networking, the data plane and the control plane are both distributed.

A

Each device has its own control and data plane. They are ‘distributed’ throughout the network. Each device has its own ARP table, etc..

Q

Why is data plane traffic generally handled by ASICs now?

A

ASICs are specifically designed for lookup and forwarding operations, so they are faster than a general purpose device CPU

A

NBI

25
Q

The NBI allows what?

A

network admins to interact with the controller, access data it gathers about the network, program it, and make changed in the network

26

REST API

28
Q

What does REST stand for (REST API)?

A

Representational State Transfer

29
Q
