Both switches and routers are part of the list of components that contribute to a secure and functioning network. In the worst case scenario, a failure can paralyze the entire IT infrastructure. This makes it all the more important to know the right use case for the corresponding hardware. In our blog "Build IT infrastructure and benefit from improved processes", you can find out how you can build an effective infrastructure.
Here you can find out how switches and routers differ from each other and how best to use them.
In short, both components are responsible for targeted data transmission, but work on different layers of the OSI model. Routers (network layer, layer 3) forward data with IP addresses across networks. Switches (data link layer, layer 2) transmit data between participants within a local network using MAC addresses. Layer 3 switches combine the tasks of both devices and can perform basic, but not advanced, router functions.
| Properties | Layer-2-Switch | Layer-3-Switch | Router |
|---|---|---|---|
| Routing properties | Not routable | Basic routing functions | Also extended routing functions |
| Only works in LAN | Works in LAN and WLAN | Works in WLAN | |
| Layer in the OSI model | Layer 2 (Data Link Layer) | Layer 3 (Network Layer) | Layer 3 (Network Layer) |
| Targeted data forwarding | Identification via MAC table | Identification via MAC table and IP address | Identification via IP address |
| Suitability | For internal communication only | For internal and partly external communication | For complex, external communication |
As the definitions of both hardware components show, a direct comparison is difficult because the two perform different tasks. Particularly in extensive networks, it is therefore less a case of switch or router, but rather switches and routers.
Layer 3 switches bridge the gap between the two devices and take on tasks from both areas.
The question remains, why are there routers if a switch combines both functions?
It is very important to emphasize that a layer 3 switch performs basic routing functions. If these are sufficient for your purposes, such a device can certainly be used for both. The fast transmission in particular makes it a popular alternative in companies that mainly consist of one location.
However, in complex company structures at the latest, it is advisable to use both the one and the other. This allows you to achieve the best performance and better monitor individual nodes within your network according to their specific function. Above all, however, extended router services are often decisive in such an environment.

Switches are suitable for home networks, small offices and even complex networks. A switch is used to forward data to the correct destination device. If you want to connect several devices to a LAN (local area network) via cable, switches are used. This not only improves network performance, but also prevents data collisions. In addition, switches allow you to expand the number of LAN connections if a router does not have enough ports for all devices. A switch thus serves as an extension of the network. You can choose between managed switches with advanced features and unmanaged switches if no complex configuration is required.
Routers are suitable for smaller flats, households with few devices and low data traffic. They are inexpensive and provide a good basis for network coverage. Traditional routers are used when a high-bandwidth Internet connection is required but there are no special coverage requirements. Conventional routers are also well suited when only a small number of devices need to be connected. It is important to check the connection type of the network and ensure that the router supports at least two Wi-Fi frequency ranges (2.4 GHz and 5 GHz). Modern routers also offer greater security through web filters and access controls.
The combination of a switch and router is particularly well suited for expanding the number of network connections. The router is responsible for connecting the home network to the internet, while the switch connects wired devices to the local network. A cable is connected from a LAN port on the router to a port on the switch. Additional devices can then be connected to the network via LAN. The switch allows you to expand the number of wired connections. This ensures a fast and stable connection, ideal for bandwidth-intensive applications.
