Description

Introduction

Multiprotocol Label Switching (MPLS) is a high-performance data-carrying technique used to route network traffic efficiently. Unlike traditional IP routing, MPLS uses labels to make forwarding decisions, reducing latency and improving traffic flow. It is widely used by service providers and enterprises for scalable, secure, and high-speed networking solutions. This course covers the core concepts, architecture, and applications of MPLS, providing a strong foundation for network professionals.

Prerequisites

• Basic understanding of networking concepts such as IP routing and switching.
• Familiarity with TCP/IP, subnetting, and network protocols.
• Exposure to enterprise networking or service provider environments is beneficial but not required.
