Perhaps in today’s network systems, Poe switch is a device that is no longer strange. The switch is an effective support device for systems. For large networks, the use of Switch is indispensable. In the following article we will help you answer the concept of what a Switch is, and the role and characteristics of the Switch.

What is poe switch?

The switch is a network device good to connect network segments together in a star network model. According to this model, the Switch has the role of a central device, all computers connect here. From there, the route creates a temporary link that transfers the outgoing data.

In addition, the Switch supports Full Duplex technology to expand the bandwidth of the transmission line, which other devices cannot do.

On the market today, there are many types of network switches that are commonly and widely common in different fields such as:

The switch is completely Optical

Generally, the network switch only supports additional optical ports (Ethernet Support SFP).

When you want to choose to buy genuine Poe switch, you can freely choose reputable network switch brands such as: Sailsky.

Switch devices connect networks together. Essentially, Switches are the traffic police of a simple local area network.

How does poe switch?

An Ethernet-based LAN switch reads incoming TCP/IP data packets containing destination information as they pass on one or more input ports. The destination information in packets is good to determine which output port is used to send data to its intended destination.

Poe switch are like hubs, only smarter. A simple hub connects all the nodes on the network – essentially communicating in an inconvenient way with any device trying to communicate at any time, leading to conflicts.

On the other hand, a switch creates an electronic tunnel between the source and destination ports for a second that no other traffic can enter. Moreover, this will lead to communication without conflict.

Switches will also be similar to routers, but a router has the additional ability to forward packets between different networks. A Switch restricts to node-to-node communication on the same network.

How is the principle of operation of a switch different from a hub?

In the most basic networks, devices are connected to hubs. But there is a limit to how much bandwidth users can share on a hub based network. The more devices that add to the network, the longer it takes for data to reach its destination. Moreover, a switch avoids these and other limitations of central networks.

How does a Switch network device compare to a router? Switches allow different devices on the network to communicate. Poe switch different networks to communicate.

A router also connects networked computers to the Internet, so multiple users can share the connection. And a router acts like a dispatcher. It chooses the best route for information to travel and let it be transmitted as efficiently as possible.

What is the role of the Switch?

Switch plays a very important and indispensable role with the following outstanding uses:

Switch devices play an important role in the network system

The switch makes it possible for hosts to operate in full-duplex mode (can read – write or listen – speak) at the same time.

Moreover, the switch only establishes a virtual circuit between the two respective ports without affecting the traffic on the other ports.

The switch decides to forward frames based on the MAC address, so it is classified as a Layer 2 device. It is because the switch has the ability to choose the path to decide to forward frames that the LAN can operate much more efficiently. More than that can help reduce the error rate in the frame.

How does Poe switch connect various devices?

Generally, devices are connected indirectly through the ports of the switch. The switch knows which host to connect to its port by learning the source MAC address in the frame it receives.

No need to share bandwidth. What principle of bandwidth is transmitted will be determined by the port of the switch device. Therefore, it is possible to limit the transmitted traffic to a certain threshold level.

Poe switch acts as a controller and allows networked devices to effectively ‘talk’ to each other. Thereby helping to allocate resources and enhance business savings, increase employee productivity.

Features of Switch devices

To better understand what a Switch device is, read on to learn more about the unique features and characteristics of this type of device.

Separating traffic on each network segment, Ethernet Switches divide the network into very small units called microsegments. Segments allow multiple users on different segments to send data at the same time without slowing down network operations.

Each segment is a separate collision domain. Bandwidth-limiting switches only forward packets to the correct port required based on Layer 2 MAC addresses.

The switch ensures more bandwidth to the users by creating smaller collision domains. Each of these segments is a separate connection like a 100Mbps private lane.

Through the above article, we hope to give you an overview of the switching device.  We hope that after this article, readers can answer the question of what poe switch is, its uses and Switch characteristics.

Switch device role

In the network base, Switch plays an important role in making LAN stable and high performance thanks to its ability to create a virtual connection path between 2 devices without affecting other connections.

Similar to a Switch is a Hub device. Basically, these two devices take on the same roles, but the Switch is smarter thanks to the ability to create a virtual path to connect separately between the two devices, ensuring full bandwidth.

Switch roles:

The switch only establishes a virtual circuit, between the two corresponding ports without affecting traffic on other ports.

The Poe switch decides to forward frames based on the MAC address. Therefore, this converter is classified as a layer 2 device. It is thanks to this function that the LAN can operate stably and effectively. It also helps to reduce the error rate in the frame.
