Citrix NetScaler Essentials and Traffic Management

This course will provide the knowledge and skills to implement and management Citrix NetScaler and is suitable for delegates with little, or no, previous experience of NetScaler. Part 1 (days 1-3) focuses on NetScaler essentials, while part 2 (days 4-5) focuses on traffic management. 

Who's it for?

This course is for administrators, engineers/implementers and architects interested in learning how to implement and manage the advanced NetScaler features.

Key objectives

After attending this course a delegate will be able to:

  • identify the functionality and capabilities of the NetScaler
  • explain basic NetScaler network architecture
  • obtain, install and manage NetScaler licenses
  • describe how SSL is used to secure the NetScaler
  • optimise the NetScaler system for traffic handling and management
  • customise the NetScaler system for traffic flow and content-specific requirements
  • employ recommended tools and techniques to troubleshoot common NetScaler network and connectivity issues
  • implement NetScaler TriScale technology, including clustering
  • configure advanced load balancing and GSLB on the NetScaler system.


Delegates should have basic understanding of:
