Introduction

Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) is essential for optimizing network performance, improving bandwidth utilization, and ensuring Quality of Service (QoS). By enabling efficient path selection and resource allocation, MPLS TE allows enterprises and service providers to enhance network reliability and scalability. This course provides a comprehensive understanding of MPLS TE principles, configurations, and best practices to optimize network traffic.

Prerequisites

• Basic understanding of networking concepts (IP routing, subnetting, and switching).
• Familiarity with MPLS architecture and Label Distribution Protocols (LDP, RSVP-TE).
• Experience with routing protocols such as OSPF or IS-IS.
