What is Star Bus Topology?

Star Bus is a networking topology in which hubs for workgroups or departmental local area networks (LANs) are connected by using a network bus to form a single network. Star bus topology is a combination of star topology superimposed on a backbone bus topology.

You can connect hubs by using one of the following:

  • Regular 10Base2 or 10BaseT cables with uplink ports on the hubs
  • Crossover cables for regular (host) ports on the hub
  • Special cables for stackable hubs

TIP


When you use this topology with standard Ethernet hubs, do not create an excessively large collision domain by adding too many stations. This will degrade network performance unless you segment the network by using bridges or routers.
