Router is a physical equipment that passes data between two or more networks. A router inspects given data packet destination, which calculates the best way for it to reach its destination and then redirects it accordingly.
Types of routers
Core routers are generally used by service providers (i.e. AT&T, Verizon, Vodafone) or cloud providers (i.e. Google, Amazon, Microsoft). They provide maximum bandwidth to connect additional routers or switches. Most small businesses will not need core routers. But very large enterprises that have many employees working in various buildings or locations may use core routers as part of their network architecture.
An edge router, also called a gateway router or just “gateway” for short, is a network’s outermost point of connection with external networks, including the Internet.
Edge routers are optimized for bandwidth and designed to connect to other routers to distribute data to end users. Edge routers don’t usually offer Wi-Fi or the ability to manage local networks fully.
They typically have only Ethernet ports—an input to connect to the Internet and several outputs to connect additional routers.
Edge router and modem are somewhat interchangeable terms, though the latter term is no longer commonly used by manufacturers or IT professionals when referencing edge routers.
A distribution router, or interior router, receives data from the edge router (or gateway) via a wired connection and sends it on to end users, typically via Wi-Fi, though the router usually also includes physical (Ethernet) connections for connecting users or additional routers.
Wireless routers, or residential gateways, combine the functions of edge routers and distribution routers. These are commonplace routers for home networks and Internet access.
Most service providers provide full-featured wireless routers as standard equipment. But even if you have the option to use an ISP’s wireless router in your small business, you may want to use a business-level router to take advantage of better wireless performance, more connectivity controls, and security.
Virtual routers are pieces of software that allow some router functions to be virtualized in the cloud and delivered as a service. These routers are ideal for large businesses with complex network needs. They offer flexibility, easy scalability, and a lower entry cost. Another benefit of virtual routers is reduced management of local network hardware.
Next-generation firewalls (NGFWs) filter network traffic to protect an organization from internal and external threats. Along with maintaining features of stateful firewalls such as packet filtering, IPsec and SSL VPN support, network monitoring, and IP mapping features, NGFWs possess deeper content inspection capabilities. These capabilities provide the ability to identify attacks, malware, and other threats, and allow the NGFW to block these threats. NGFWs provide organizations with SSL inspection, application control, intrusion prevention, and advanced visibility across the entire attack surface.
