   - `./topo/with-vdsl.yml` - A topology mixing datacenters with fast internal connectivity and an isolated VDSL node
   - `./topo/50ms.yml` - An artifical topology simulating nodes with high bandwidth but with a fixed 50ms latency, useful to quantify the impact of latency on a distributed software
   - `./topo/multi-dc.yml` - Simulate 3 DC interconnected with 50ms latency WAN network and close to zero latency inside the DC
-  - `./topo/slow.yml` - Simulate 3 nodes interconnected with a low latency, very low bandwidth link. Useful to debug bandwidth bottlenecks
+  - `./topo/{1,5,10,50,100}mbps.yml` - Simulate 3 nodes interconnected with a bandwidth bottleneck.
 
 Feel free to write new topologies!
