Today, networks must support increasing numbers of devices, including smartphones and tablets, Internet of Things (IoT) devices, and a host of other connected systems. Organizations are also adopting AI-powered tools, which require a constant flow of data. In light of these trends, network switches have become increasingly important.
However, many have aging switches that lack the bandwidth and performance to meet today’s demands. Older switches may no longer be supported by the vendor, increasing the risk of downtime or a security breach. An upgrade is in order, but what type of network switches does your organization need?
Network Switches: The Basics
A network switch is a device that connects different network segments and devices, allowing data packets to be sent, received, processed and monitored. Without switches, there could be no communication between network devices. A network switch also makes it possible for multiple devices to share a wired Internet connection.
The typical small to midsize enterprise has one or more of these four types of switches.
- Unmanaged: These plug-and-play switches are the easiest to use but have no configuration options. They are most suitable for home and small business settings.
- Smart/Lightly Managed: These switches have a limited range of management and control options, usually through a very simple, browser-based interface. Basic security features and Quality of Service are typically supported.
- Managed: These switches have advanced controls that allow precise configuration and optimization to suit specific requirements and deliver the best possible user experience. They also provide information that facilitates network troubleshooting.
- Stackable: Stackable switches can be physically connected such that they act as a single logical switch. They enable smaller networks to scale gradually and cost-effectively by simply adding more units to the stack.
Most organizations use multiple types of switches within different parts of the network infrastructure. Large organizations often have multiple tiers of switches, including core, distribution and access switches, each with different capabilities.
Factors to Consider When Choosing Network Switches
Choosing the right network switches depends on a number of factors:
- Current and future device count. Determine how many devices need to be connected and choose a switch with enough ports to accommodate them. Be sure to anticipate growth and consider any planned initiatives that could add to the device count. If growth rates are rapid or unpredictable, consider stacked switches.
- Connection speed requirements. Determine the maximum data rate needed for specific applications, and choose switch ports that will meet current and future requirements. It’s important to take Wi-Fi speeds into account as the wired network serves as the foundation for the wireless network.
- Switch type / management capabilities. While unmanaged switches might be sufficient for workgroup hubs, most organizations will need some management features. Consider whether a smart switch will be adequate or if a managed switch is needed.
- Power over Ethernet (PoE) capabilities. PoE switches supply DC power over network cabling, enabling them to support low-power devices without a separate power source. Choose a PoE-enabled switch to power devices such as desk phones, IP cameras and wireless access points.
There are also advanced capabilities to consider, such as Quality of Service features for prioritizing specific types of network traffic and Layer 3 functionality for routing traffic between different subnets. Some switches also incorporate security features such as port security and access control lists.
