Overview

Layer 2 Network Architecture Design and Performance - Basic provides an overview 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 Ethernet Switching PB, PBB, PBB-TE and associated protocols STP, RSTP
  • Understand the purpose and behaviour of Virtual LANs
  • Describe how VLANs and point-to-point services can be supported over MPLS platforms
  • Describe the architecture and components of Carrier Ethernet Services
  • Describe how VLANs and point-to-point services can be transported over Carrier Ethernet platforms
  • Identify how Quality of Service, synchronization, and security can be guaranteed
  • Understand how Fault Management and Performance Monitoring can be performed
  • Describe the role of MPLS-TP

Target Audience

Who Should Attend: 

Anyone requiring a basic knowledge of Layer 2 Networking technologies and their capabilities, and how they can be deployed and managed. This includes Sales Engineers, Solutions Architects, Network Engineers, and other job roles.
