Overview

Layer 2 Network Architecture Design and Performance - Advanced provides a more thorough view of Layer 2 technologies and how they can be used to support a variety of services. It details Ethernet Switching principles (PB, PBB, and PBB-TE), and Carrier Ethernet Services and identifies how Layer 2 services (point-to-point and multipoint) can be transported over PB, PBB, Carrier Ethernet, and MPLS platforms. The course examines how Quality of Service, synchronization, and security aspects are supported, and how Fault Management and Performance Monitoring can be performed.

Objectives

Upon completion candidates will be able to:

  • Describe Layer 2 services
  • Understand and describe Ethernet Switching PB, PBB, PBB-TE and associated protocols STP, RSTP
  • Understand and define the purpose and behavior of Virtual LANs
  • Describe how VLANs and point-to-point services can be supported over MPLS platforms
  • Understand and describe the architecture and components of Carrier Ethernet Services
  • Describe how VLANs and point-to-point services can be transported over Carrier Ethernet platforms
  • Understand and identify how Quality of Service, synchronization, and security can be guaranteed
  • Understand and describe how Fault Management and Performance Monitoring can be performed
  • Understand and describe the role of MPLS-TP

Target Audience

Who Should Attend:

Anyone requiring a more in-depth knowledge of L2 networking technologies and their capabilities, and how they can be deployed and managed. This includes Sales Engineers, SolutionsArchitects, Network Engineers, and other job roles.
