This course will provide a practical overview to implementing Next Generation core network technology solutions. It will introduce the key core network technologies, their performance profiles and how to size services to provide performance requirements specification for the core. It will then teach how to design core networks to match to requirements profiles to delver services matching QoS and Availability specifications.

The class will be divided into groups and each group given a case study specification. The groups will be required to analyse these and make two presentations. In the first they will present a statement of the requirements with the potential design problems to be solved. In the second they will present the results of sizing calculations and proposed design solutions, together with validation tests for proving that the design meets the requirements.


Upon completion of the course, delegates will be able to:

  • Describe the key technologies used in building Next Generation Core Networks
  • Compare and contrast the use of Carrier Ethernet, SDH, Fiber optics and other core technologies
  • Design MPLS base solutions for core technologies
  • Size access and infrastructure services to deliver core network requirements
  • Identify the core network requirements from key services such as voice, IPTV and business VPNs
  • Specify the appropriate VPN and Security services required for reliable deployment
