Overview
A router is a networking device that directs data packets between computer networks. It acts as a traffic manager, ensuring information moves efficiently from one network to another, typically between a local network (like an office LAN) and the internet. Routers are essential for enabling multiple devices to share a single internet connection securely and reliably.
How It Works
-
Packet forwarding: Routers examine the destination IP address of each packet and determine the best path to forward it.
-
Network segmentation: By connecting different networks, routers keep traffic organised and reduce congestion.
-
NAT (Network Address Translation): Allows multiple devices on a private network to share a single public IP address.
-
Firewall capabilities: Many enterprise routers include security features to block unauthorised traffic and filter data.
Key Features
-
Connectivity: Connects LANs, WANs, and the internet.
-
Performance: Supports high throughput for enterprise-grade workloads.
-
Security: Provides encryption, VPN support, and integrated firewall functions.
-
Scalability: From home routers to carrier-grade devices supporting thousands of connections.
Use Cases
-
Enterprise networking: Manages traffic between corporate offices and the internet securely.
-
Branch connectivity: Links remote branches to headquarters or cloud services.
-
Home networking: Distributes broadband connections to multiple devices.
-
Service providers: Backbone routers direct large-scale internet traffic across regions and countries.
