Which ethernet switch

Therefore, it is more intelligent and efficient than an Ethernet hub which is unable to distinguish different recipients. As for how to choose an Ethernet switch, there are different factors you should consider:.

Speaking of how to use an Ethernet switch, you can follow the guidance below:. For more details, you can refer to the post of how to use a network switch. In short, An Ethernet switch is a telecommunication device used to connect multiple computers or devices together and can expand network with ease. Understanding Network Latency in Ethernet Switches.

Address Learning -- Ethernet switches control how frames are transmitted between switch ports, making decisions on how traffic is forwarded based on bit media access control MAC addresses that are used in LAN standards. An Ethernet switch can learn which devices are on which segments of the network using the source addresses of the frames it receives. Every port on a switch has a unique MAC address, and as frames are received on ports, the software in the switch looks at the source address and adds it to a table of addresses it constantly updates and maintains.

This table is also known as a forwarding database, which is used by the switch to make decisions on how to filter traffic to reach certain destinations. Traffic Filtering -- Once a switch has built a database of addresses, it can smoothly select how it filters and forwards traffic. As it learns addresses, a switch checks frames and makes decisions based on the destination address in the frame.

Switches can also isolate traffic to only those segments needed to receive frames from senders, ensuring that traffic does not unnecessarily flow to other ports. If an entry is dropped—meaning it once again is unknown to the switch—but traffic resumes from that entry at a later time, the switch will forward the frame to all switch ports also known as frame flooding to search for its correct destination. When it connects to that destination, the switch once again learns the correct port, and frame flooding stops.

Multicast Traffic -- LANs are not only able to transmit frames to single addresses, but also capable of sending frames to multicast addresses, which are received by groups of endpoint destinations. Broadcast addresses are a specific form of multicast address; they group all of the endpoint destinations in the LAN. Multicasts and broadcasts are commonly used for functions such as dynamic address assignment, or sending data in multimedia applications to multiple users on a network at once, such as in online gaming.

Streaming applications such as video, which send high rates of multicast data and generate a lot of traffic, can hog network bandwidth. Unmanaged Ethernet switching refers to switches that have no user configuration; these can just be plugged in and turned on. Managed Ethernet switching refers to switches that can be managed and programmed to deliver certain outcomes and perform certain tasks, from adjusting speeds and combining users into subgroups, to monitoring network traffic.

Fortinet switches offer advanced features in a simple, easy-to-manage solution, including the ability to enable full security features without slowing down performance. The switch also delivers PoE power-over-ethernet capability, making it easier for businesses to hook up IP cameras, VoIP phones, wireless access points and other standards-compliant powered devices.

He dabbled in website building and web hosting when DHTML and frames were en vogue and started writing about the impact of technology on society just before the start of the Y2K hysteria at the turn of the last millennium. Then followed a weekly tech column in a local business magazine in Mauritius, a late night tech radio programme called Clicplus and a freelancing gig at the now-defunct, Theinquirer, with the legendary Mike Magee as mentor. Following an eight-year stint at ITProPortal.

He has an affinity for anything hardware and staunchly refuses to stop writing reviews of obscure products or cover niche B2B software-as-a-service providers. North America. Included in this guide: 1. Any office with a lot of devices needs to invest in the best network switches available.
