Definitive network virtualization

Description

This course covers network virtualization. It has been
designed to enable network engineers to recognise and
handle the requirements of networking Virtual
Machines. Both internal and external network
virtualization is covered along with the technologies
used to map overlay networks on to the physical
infrastructure. Hands on sessions are used to reinforce
the theory rather than teach specific manufacturer
implementations.
