The PoE technology, which has been applied to many devices and fields since born, to help our life smarter and easier. And the Ethernet (network) switch, playing an important part in data center or networking now,  is one of the applied devices. Now, you may have doubts what is the Ethernet switch, and what does it do in the networking. The following is the answer.

WHAT IS THE ETHERNET SWITCH?

An Ethernet switch is a hardware device that centralizes communications among various connected devices in one local area network (LAN). It connects devices together by using packet switching to receive, process, and forward data from one source device to another destination device.

WHAT DOES THE ETHERNET SWITCH DO IN THE NETWORKING?

Here take the comparison among router, hub and switch to explain what an Ethernet switch can do for our networks.

* Providing more Ethernet ports than a router does.

* Providing more smarter data transmission than a hub does.

Send the data to all devices in the network - Hub

Send the data to the specific device you want - Ethernet Switch

ETHERNET SWITCH ON DIFFERENT HIERARCHICAL INTERNETWORKING MODELS

Generally, the hierarchical internetworking models are defined as the core layer, aggregation layer, and access layer. Therefore, the Ethernet switches working in these layers get corresponding names like core switch, aggregation switch, and access switch. Here is a summary of their basics as follows.
