Ethernet Switching

Prior to the establishment of Ethernet Switches in 1990, the most popularly used forms of Local Area Network (LAN) connectors were the hubs and repeaters. Generally, connectors function just like their name implies; they are the platforms that allow connections between several computers.

But the specific Ethernet Switches function at the OSI model’s data link layer 2. Categorized under “network bridges”, these switches are unlike the also known router. With Ethernet switching, information transfer happens to all connected network devices regardless of which is which. With routers, on the other hand, relay of data is restricted to a specific device in the network.

In the Ethernet networking technology, the term Bridges could take the place of Switches and the same applies to the other way around. However, in order for a connector to have the honor of being called a “Switch”, it must pass and be able to work based on the 802.3 standard that is primarily used for Ethernet networking.

Ethernet Switching, although highly similar with the previously mentioned hubs and repeaters, are technically more advanced and efficient. The Switching technology allows device linkages to work in full duplex mode, while the two earlier versions only allow half duplex.

Meaning, with switching, receiving and sending out of data transmissions can take place at the same time. Whereas, for the other two, these processes have to be done alternately.  In much simpler terms, the switching technology makes better use of both bandwidth capacity and time.

There are also a lot of other advantages of Ethernet Switching that makes it the current best choice for networking needs.

One example is that switches have the capabilities of filtering data. The switches can analyze specific types and forms of data being transferred, so it can determine the exact location they are intended to be placed. Hence, they make transferring easier and the flow of bandwidth traffic lighter.

Also, switches can save and detect the certain MAC addresses of the linked computers so it can speedily discern from where and to where important signals are supposed to go. The previous forms of connectors didn’t have this facility and therefore were known to be capable of having large bandwidth wastes.

Variants of Ethernet switches vary depending on the performance they were made to cater. With high regard on the type and form of network they are targeted for, these switches also have varying performances. Smaller types are typically called Unmanaged Switches.

Their configurations are already fixed and can no longer be adjusted. Because of their uncomplicated nature and plug-and-play features, they are mostly used in small offices and homes where users are not very critical about their networking needs. And then there are the medium to large types called Managed Switches.

These are the ones that could be adjusted and modified based on the preference of the user. Their greatest features include Virtual LANs, which allows the head computer to see all transactions and data exchanges happening between all linked devices. They are perfect for large networks like big-time companies, because of their more sophisticated service offers.

Switches can also be acquired in both non-standardized or IEEE 802.3 standardized types. As always, Ethernet Switching is just one of the constantly developing technologies for our networking needs. With the great form of assistance it provides us today, it is just to be expected that they will always be a part of our expanding technological horizon.
