Bus topology
- Uses a trunk or backbone to which all of the computers on the network connect.
- Systems connect to this backbone using T connectors or taps.
- Coaxial cablings ( 10Base-2, 10Base5) were popular options years ago.
Bus Topology
Ring Topology
- Logical ring
- – Meaning that data travels in circular fashion from one computer to another on the network.
- – Typically FDDI, SONET or Token Ring technology are used to implement a ring network
- – Ring networks are most commonly wired in a star configuration
- Token Ring has multi-station access unit (MSAU),equivalent to hub or switch. MSAU performs the token circulation internally.
Star Topology
- All computers/devices connect to a central device called hub or switch.
- Each device requires a single cable
- point-to-point connection between the device and hub.
- Most widely implemented Hub is the single point of failure
Mesh Topology
- Each computer connects to every other.
- High level of redundancy.
- Rarely used.
- Wiring is very complicated
- Cabling cost is high
- Troubleshooting a failed cable is tricky
- A variation hybrid mesh – create point to point connection between specific network devices, often seen in WAN implementation.
