Where to Buy Ethernet Network Switches

Ethernet Network Switches
  • Reduce network downtime
  • Improve network performance
  • Increase available bandwidth on your network
  • Reduce strain on individual host computers suffer with lower workloads
  • Protect your corporate network with more robust security features
  • Reduce IT costs with remote management options as well as reduced wiring expenses
  • Provide unique network switch connections to specific workstations for further customization
  • Streamline future expansion with the use of modular switches

An Ethernet switch creates networks and uses multiple ports to communicate between devices in the LAN. Ethernet switches differ from routers, which connect networks and use only a single LAN and WAN port. A full wired and wireless corporate infrastructure provides wired connectivity and Wi-Fi for wireless connectivity.

Features of Ethernet Switches

  • Store and Forward Switches: Store and forward switches read and buffer the complete data packet on an incoming port. The switch checks the whole frame for errors and, if error free, sends it out the relevant port.
  • Cut-Through Switches: Cut-through switches give less delay than store and forward switches. They forward the frame directly once the destination address is determined. The switch will buffer only as many bytes of the data packet to obtain the destination address.
  • Port Mirroring: Port mirroring is a helpful function for diagnostics in a network. It provides a copy of all the inbound and outbound data from one port (the mirrored port) of a switch to another port (the mirror port). Most switches with port mirroring capabilities allow the selection and configuration of the mirrored and mirror port from a web-page in the switch.
  • Power over Ethernet (PoE): Devices with this capability receive power over the Ethernet cable.
  • Gigabit Ethernet: In the implementation of PROFINET networks with a transmission rate of 1,000 Mbit (1 Gbit), switches should also support this transmission rate.
  • Auto-Sensing / Auto-Negotiation: Auto-sensing describes the ability of a device to automatically identify the transmission rate of a signal. Additionally, auto-negotiation allows the involved devices to negotiate and agree upon a transmission rate before the first data transmission.
  • Auto Cross-Over: The function provides automatic crossing of transmit and receive lines at a port interface. If it is deactivated, a cross-over cable or a switch with port wiring for crossing of connections is sometimes required.
  • Redundancy Support: Redundancy support allows for bumpless or non-bumpless changeover of failed links to a redundant link.
