Definitive WANs for engineers

Description

WAN training course description

A hands on Introduction to Wide Area Networks for engineers. This course covers all current major WAN technologies from a perspective of design, evaluating technologies available as well as hands on to consolidate the theory

What will you learn

• Describe the seven-layer model and realise how it applies to the real world.
• Evaluate and describe WAN technologies.
• Describe the architecture of WANs in the core.
• Use WANS to interconnect LANS.
