2. What is the largest disadvantage of NFV?
3. To what layer are the servers connected in a layered network topology?
4. When is a spine and leaf network preferred over a layered network topology?
5. What is the difference between an IDS and an IPS?
1. SDN
SDN stands for Software Defined Network. In this architecture, the control plane is separated from the data plane. It is implemented in a software application.
The controller is the most important component of the SDN architecture.
The largest security risk of SDN:
2. NFV
NFV stands for Network Function Virtualization.
It is used for the decoupling of network functions from the proprietary hardware and running them like the software in virtual machines.
The infrastructure is independent of the hardware.
The largest disadvantage of NFV:
The three components of NFV are- NVF manager, VNFs, and the NFV infrastructure.
These components are joined together. So, it adds complexity and difficulty when deployed at the NFV scale.
Other disadvantages are:
