What is a Gigabit switch?
Gigabit Ethernet (1000 Mbps) is an evolution of fast Ethernet (100 Mbps) and is one of the cost-effective networks for a variety of home networks and small businesses to achieve multi-meter stable network connections.
Gigabit Ethernet switches are widely adopted to boost data rates to around 1000 Mbps, while fast Ethernet supports 10/100 Mbps transmission speeds.
As a higher version of high-speed Ethernet switches, gigabit Ethernet switches are valuable for connecting multiple devices, such as security cameras, printers, and servers, to local area networks (LAns).
In addition, gigabit network switches are a great choice for video creators and video game anchors who need hd equipment.
How does a Gigabit switch work?
Usually, gigabit switches allow multiple devices through coaxial cable, twisted pair Ethernet cable and optical fiber cable to connect to the LAN, and gigabit Ethernet switches use belongs to only the MAC address of each device on a given port to receive each frame recognition of connected devices, so that it can correctly will frame is routed to the destination as needed.
Then gigabit switches is responsible for the management of their own, other connected devices, cloud services and the Internet, the data flow between the device connected to the gigabit network switch port of that a moment, to the incoming and outgoing data transfer to the correct Ethernet switch ports according to the transmitting device and the sending and target MAC address.
Next, when a Gigabit network switch receives an Ethernet packet, the gigabit switch uses a MAC address table to remember the MAC address of the sending device and the port to which the device is connected. Switching technology checks the MAC address table to see if the destination MAC address is connected to the same switch.
If the answer is yes, the Gigabit Ethernet switch continues to forward packets to the destination port. If not, the gigabit switch sends the packet to all ports and waits for a response.
Finally, while waiting for a response. Assuming a gigabit network switch is connected to the destination device, the device will accept packets. If the device is connected to another gigabit switch, the other gigabit switch repeats until the frame reaches the correct destination.
Type of gigabit switches
Gigabit Ethernet switches have various ports, such as 8-port Gigabit switches and 24-port Gigabit switches. The following are other gigabit switch types to consider.
Modular network switches and fixed network switches
These fixed-configured switches have a fixed number of ports, such as 24-port GIGABit switches and 48-port gigabit switches.
In contrast, modular switches allow users to add expansion modules to gigabit Ethernet switches as needed. For example, you can add modules that support security, wireless connectivity, and so on.
Non-network management Gigabit switch and network management Gigabit switch
These unmanaged gigabit switches are designed to plug and play without configuration and typically represent home networks and small businesses.
Managed Gigabit switches support higher levels of security, scalability, and precise control and management of your network, so managed gigabit switches are typically used on large networks.
Independent switches and stackable switches
A single gigabit switch is managed and configured with a set capacity. An independent switch needs to be configured and rectified separately.
One big advantage of stackable gigabit switches is increased capacity and network availability. Stackable switches allow multiple switches to be configured as one entity. If any part of the stack fails, these stackable switches will automatically rerouted around the failure without affecting data transfer.
PoE and non-POE gigabit switches
PoE Gigabit switches can power devices such as IP cameras or wireless access points over the same Ethernet cable, greatly increasing the flexibility of connecting systems.
PoE gigabit switches are ideal for wireless networks, while non-poe switches perform poorly in wireless networks because non-poe gigabit switches transmit data only over Ethernet cables.
How do I install a Gigabit network switch?
First, connect one end of the Ethernet cable to the output port of your modem or router.
Second, connect the other end of the Ethernet cable to the port on the Gigabit Ethernet switch.
Third, prepare another network cable and connect one end of the cable to another port on the gigabit network switch.
Finally, plug the other end of the Ethernet cable into your desired device and the installation is successful.
