An Ethernet Switch connects devices in the local area network to the company's main site or other remote locations with a wired or wireless connection. Ethernet Switches vary from routers that connect large networks in to a local area network using merely a single LAN port and WAN port, to split routers, which have two separate and distinct ports for Ethernet traffic. An entire wired and wireless corporate structure provides router-based services and optional wireless networking by having an Ethernet switch. Some well-known switch vendors include Linksys, D-Link, Netgear, and Microsoft.
To be able to know how traffic is managed on an Ethernet Switches, it is useful to have an knowledge of how many computer networking functions. At the core of all computers, networking is the technology of frames. These are packets of data which can be sent and received over a network of physical links. Frames are received and sent by devices such as for instance web browsers, personal computing equipment, cellular phones, and other wireless devices and are routed by the network routing protocols to offer a path for the traffic. This way, all outgoing traffic on an Ethernet network is routed by the same pair of protocols and the same process for forwarding traffic.
The next layer of software on these devices is referred to as the layer 2 traffic protocol (L2TP). L2TP forwarding begins with a source device that broadcasts an address onto the network that's received by active layer 2 routers. These routers then send the received packets of information to active layer 3 (input) devices that continue the received data. The final layer of traffic that's routed through Ethernet Switches is called the encapsulated layer 3 traffic, that is sent over an ethernet cable to reach its destination.
There are several types of devices that can be found in a property or office setting that utilize Ethernet Switches. For instance, there are certain computers which can be classified as "rural" where there's no additional computer hardware open to be connected. That is particularly true in a property or office setting where multiple devices will share a notebook or other local computer resources. The primary benefit provided by these devices is that they give a redundant connection that can withstand several natural disasters or adverse weather conditions. In addition, it's common for some type of computer or other networking device in a rural setting to own a unique power supply, insurance, and other services that can make the utilization of a regular Ethernet Switch impractical.
