At which layer of network do we use a switch to forward a packet? Based on which Address?

May 13th, 2015

LAN switching is a form of packet switching used in local area networks (LAN). Switching technologies are crucial to network design, as they allow traffic to be sent only where it is needed in most cases, using fast, hardware-based methods. LAN switching uses different kinds of network switches. Basic switch is marked as layer 2 switch and could be found in nearly all LAN around. Layer 3 or layer 4 switch requires advanced technology (see managed switch) and are more expensive, and thus could be found in larger LAN or in the special network environment.

Layer 2 switching uses the media access control address (MAC address) from the host's network interface cards (NICs) to decide where to forward frames. Layer 2 switching is hardware-based,[1] which means switches use application-specific integrated circuit (ASICs) to build and maintain filter tables (also known as MAC address tables or CAM tables). One way to think of a layer 2 switch is as a multiport bridge.

Layer 2 switching provides the following

  • Hardware-based bridging (MAC)
  • Wire speed
  • High speed
  • Low latency
