Daisy chain topology is inherently less fault-tolerant. A failure in one device or cable disrupts downstream connections. Unlike mesh or star networks, there’s no alternative data path. It’s ideal for simple systems but unsuitable for critical infrastructure that demands high uptime and robust error recovery.
1. Single Point of Failure: Every device is a vital link. If one fails, others lose access. This chain reaction makes daisy chains risky for any critical operations needing constant uptime or fault isolation.
2. No Redundancy: Daisy chains lack alternate communication paths. In case of failure, recovery requires manual repair. This is unlike mesh setups, where traffic reroutes automatically.
3. Difficult Troubleshooting: Failures affect all devices downstream. Diagnosing problems requires checking each device from the start of the chain, slowing recovery and increasing complexity.
4. Dependency on Repeaters: If repeaters are used to extend range, they too become failure points. The more devices or repeaters in the chain, the more fragile the system becomes.
5. Not Suitable for Uptime-Critical Systems: This topology doesn’t support environments like hospitals or server centers where downtime leads to major consequences. Use it only where minimal disruption is acceptable.
