Definitive network virtualization

Description

Network virtualization training course 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.

What will you learn

• Evaluate network virtualization implementations and technologies.
• Connect Virtual Machines with virtual switches.
• Explain how overlay networks operate.
• Describe the technologies in overlay networks.
