Many Carriers have been utilising MPLS for provision of core network transport. Today a family of MPLS variants, including IP/MPLS, MPLS-TE, G-MPLS, and MPLS-TP, exist that enable MPLS to be used in more innovative ways.

This 5-day in-depth course examines how MPLS in its various forms can be used to provide transport for layer 2 and layer 3 VPNs, to provide for guaranteed QoS enabled service, and to provide transport for Carrier Ethernet and Cloud connectivity in both the core and metro network.

Key areas covered in the course include the differences between the MPLS variants, the architecture and operation of each variant, what protocols are required to enable each variant to operate, how QoS and DiffServ are supported, how OAM is supported, and typical use-case scenarios for Mobile Backhaul, Carrier Ethernet, and Cloud connectivity.


Upon completion candidates will be able to:

  • Describe the differences between IP/MPLS, MPLS-TE, G-MPLS, and MPLS-TP
  • Demonstrate a knowledge of the architecture and operation of the MPLS variants
  • Demonstrate a knowledge of the protocols used within MPLS operation
  • Describe how QoS and DiffServ are used to guarantee service performance
  • Demonstrate a knowledge of OAM functionality and operation
  • Describe how Layer 2 and Layer 3 VPNs are provisioned in MPLS
  • Describe how MPLS can be used to provide core and metro network connectivity for Carrier Ethernet, Mobile Backhaul, and Cloud Computing

Target Audience

Who Should Attend:

Technical Engineers, Product Managers/Engineers, System Architects working within a Carrier network or Mobile Operator network, Carrier Ethernet/Mobile Backhaul/Cloud Computing Service Provision, and anyone requiring an in-depth knowledge of MPLS Transport Networks, VPNs and Control Plane.
