Not all networks use switches. For example, a network may be and often was, in the s and s organized in a token ring or connected via a bus or a hub or repeater. In these networks, every connected device sees all traffic and reads the traffic addressed to it. A network can also be established by directly connecting computers to one another, without a separate layer of network devices; this approach is mostly of interest in HPC contexts where submicrosecond latencies are desired and can become quite complex to design, wire and manage.

Network Switches, LAN and Enterprise Switches - Cisco

Here's a look at some common use cases and features. The main factors that affect server efficiency are inlet air temperature, humidity and contaminants. Such switches are commonly known as layer-3 switches or multilayer switches. Switches for Ethernet are the most common form of network switch.

The first Ethernet switch was introduced by Kalpana in Unlike less advanced repeater hubs , which broadcast the same data out of each of its ports and let the devices decide what data they need, a network switch forwards data only to the devices that need to receive it. A switch is a device in a computer network that connects other devices together. Multiple data cables are plugged into a switch to enable communication between different networked devices. Switches manage the flow of data across a network by transmitting a received network packet only to the one or more devices for which the packet is intended.

Each networked device connected to a switch can be identified by its network address , allowing the switch to direct the flow of traffic maximizing the security and efficiency of the network. A switch is more intelligent than an Ethernet hub , which simply retransmits packets out of every port of the hub except the port on which the packet was received, unable to distinguish different recipients, and achieving an overall lower network efficiency. Each device connected to a switch port can transfer data to any of the other ports at any time and the transmissions will not interfere.

Switches may also operate at higher layers of the OSI model, including the network layer and above. A device that also operates at these higher layers is known as a multilayer switch. Segmentation involves the use of a switch to split a larger collision domain into smaller ones in order to reduce collision probability, and to improve overall network throughput.

In the extreme case i. In contrast to an Ethernet hub, there is a separate collision domain on each of the switch ports. This allows computers to have dedicated bandwidth on point-to-point connections to the network and also to run in full-duplex mode. Full-duplex mode has only one transmitter and one receiver per collision domain, making collisions impossible.

The network switch plays an integral role in most modern Ethernet local area networks LANs. Mid-to-large sized LANs contain a number of linked managed switches. In most of these cases, the end-user device contains a router and components that interface to the particular physical broadband technology. Switches are most commonly used as the network connection point for hosts at the edge of a network.

In the hierarchical internetworking model and similar network architectures, switches are also used deeper in the network to provide connections between the switches at the edge. This connectivity can be at any of the layers mentioned. While the layer-2 functionality is adequate for bandwidth-shifting within one technology, interconnecting technologies such as Ethernet and token ring is performed more easily at layer 3 or via routing. Where there is a need for a great deal of analysis of network performance and security, switches may be connected between WAN routers as places for analytic modules.

Some vendors provide firewall , [8] [9] network intrusion detection , [10] and performance analysis modules that can plug into switch ports. Some of these functions may be on combined modules. Through port mirroring , a switch can create a mirror image of data that can go to an external device such as intrusion detection systems and packet sniffers. A modern switch may implement power over Ethernet PoE , which avoids the need for attached devices, such as a VoIP phone or wireless access point , to have a separate power supply.

Since switches can have redundant power circuits connected to uninterruptible power supplies , the connected device can continue operating even when regular office power fails. Modern commercial switches use primarily Ethernet interfaces. A switch is used to network multiple computers together.

Switches made for the consumer market are typically small, flat boxes with 4 to 8 Ethernet ports. These ports can connect to computers, cable or DSL modems, and other switches. High-end switches can have more than 50 ports and often are rack mounted.
