switches

  • Operate at the Data Link Layer
  • Increase network performance
  • Virtual circuits between source and destination
  • Micro segmentation
  • Multiple virtual circuits are called “switched bandwidth”
  • Between two computers using a switch, two collision domains are created each with dedicated bandwidth
  • Between two hubs using a switch, two collision domains are created each with shared bandwidth
  • Filter based on MAC addresses
  • Build tables in memory

ADVANTAGES

  • Increase available network bandwidth
  • Reduced workload
  • Increase network performance
  • Smaller collision domains

DISADVANTAGES

  • More expensive than hubs and bridges
  • Difficult to trace network connectivity problems through a switch
  • Does not filter broadcast traffic
