Network topologies

Network topologies

1. star topologies

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

2. mesh topologies

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