network topologies

network topologies

1. mesh topologies

   • no central node
   • partial mesh
     • not all devices are connected to each other
   • node
     • device
   • full mesh
     • all devices are connected to each other
       • ethernet connection
   • disadvantages
     • requires maintenance
     • expensive for ethernet cables
     • failure of a single node will effect all devices in a full mesh
   • advantages
     • no expensive server required
     • communications can be received through multiple connections

2. star topologies

   • central node
   • node
     • connected only to the central node
     • device
       • not connected to each other
   • advantages
     • easy to connect new nodes
     • failure of a single has no effect on any other node
   • disadvantages
     • expensive to buy server
     • could be expensive to connect several devices
