Gateways and routers are critical networking devices that enable data transmission across heterogeneous networks. Gateways act as protocol converters, facilitating communication between networks using different architectures or data formats. Routers operate at Layer 3 (Network Layer) of the OSI model, directing data packets between networks based on IP addresses. These devices form the backbone of modern communication infrastructure, supporting enterprise connectivity, internet access, and IoT integration.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Edge Routers | Connect enterprise networks to ISP networks, support high-speed packet forwarding | Corporate branch offices |
| Core Routers | High-throughput devices for backbone network infrastructure | Telecom operator networks |
| Industrial Gateways | Convert fieldbus protocols (Modbus, CAN) to Ethernet/IP | Smart manufacturing systems |
| Wireless Routers | Integrate Wi-Fi 6/5G connectivity with routing functions | Home and SME networks |
| Security Gateways | Combine routing with firewall, IDS/IPS capabilities | Government data centers |
