Gateway

Gateway
Overview

A gateway is a networking device that connects two different networks that may use different protocols. It can operate at multiple layers of the OSI model, typically from Layer 4 (Transport Layer) to Layer 7 (Application Layer).

Key Functions
  • Translates between different network protocols
  • Connects networks with different architectures
  • Acts as an entry and exit point for a network
  • Can perform protocol conversion and data reformatting
OSI Model Layers

Gateways can operate at multiple layers of the OSI model, typically from Layer 4 (Transport Layer) to Layer 7 (Application Layer). This allows them to perform complex operations such as protocol translation and data reformatting.
