Which topology survives a broken link best?
Short answer. Mesh, because it has many alternative paths.
What happens in a star if the hub fails?
The whole star network stops.
If a link fails
| Topology | Result |
|---|---|
| Bus backbone | All stop |
| Star cable | One node off |
| Ring link | Ring stops |
| Mesh link | New path |
Remember
| Mesh survives best |
| Bus and ring break |
One cable breaks. Does the whole network stop? It depends on shape. A broken bus backbone stops all. A star loses one node. A ring stops. A mesh finds another path. Remember. Mesh survives best. Bus and ring break.
