IP Engineering & Networking

Course Description:

This course takes delegates through engineering techniques, as well as applications and protocols, enabling them to work confidently and effectively in the IP environment. The course opens with an overview of IP networks, protocols and switching methods, moving on to network services and the protocols that support them. Section 3 covers service provider architectures. The course closes with topics such as QoS, security, VPNs and Multimedia over IP Applications.

Who will Benefit:

Those needing to understand how IP networks are designed and implemented.


It is desirable that delegates are familiar with the operation of packet switched data networks and the Internet.

Technical Level:
