Course benefits
Many organisations are now completely dependent on networks for their line of business operations, yet many networks have outgrown their original design capacity and are running in a non-optimal state.
This unique course provides an essential and practical coverage of advanced LAN support techniques, and demonstrates methods for obtaining performance and reliability from today's Local and Wide Area networks, many of which are not documented elsewhere.
You will learn how to
In just three days, you will gain an essential understanding of network operation, analysis, characterisation, optimisation and troubleshooting.
You will also learn to use a practical and structured methodology for identifying and locating network problems, including the use of standard and third party utilities, cable testers, network monitors and protocol analysers.
Who should attend?
This unique course has been designed to meet the needs of people responsible for the support, management, installation or design of Local or Wide Area networks. IT support staff and network managers will find this course invaluable.
Pre-requisites
Delegates should have some practical experience of networking prior to attending the course. Course 301: Introduction to Datacomms and Networking, is recommended as a minimum level of experience.
