How is Ethernet speed is distributed in network switches

Ethernet speed distribution in network switches depends on the switch's capabilities and configuration:

  • Port Speed: Each port on a switch can have a different speed (e.g., 10/100/1000 Mbps). Devices connected to these ports communicate at the designated speed.
  • Switch Fabric: High-speed switches have a switch fabric that determines the overall throughput the switch can handle, often expressed in Gbps.
  • Backplane Speed: The backplane speed connects the switch's internal components. It affects how much data the switch can handle simultaneously between its ports.
  • QoS (Quality of Service): Switches can prioritize certain types of traffic to ensure critical data (such as VoIP) gets higher priority and better speed.
  • Buffering: Switches use buffers to temporarily store incoming data. Proper buffer management helps maintain speed during traffic spikes.
