9. Network Slicing
Before Slicing
After slicing
Allows slicing of one physical network into multiple, virtual, end-to-end (E2E) networks, each logically isolated.
E2E network
Install network function software onto VMs deployed on virtual commercial servers
Network Function Virtualization (NFV)
Software-defined networking (SDN)
Pre-requisite for implementation
separate the control and data planes
