Inject real faults into a simulated Software-Defined Data Center edge network. Watch BFD/BGP failover, DPU offload physics, and recovery telemetry — all in your browser.
Each component below maps to a real production construct in a Software-Defined Data Center edge deployment.
NSX-T Tier-0 gateway running BGP peering with upstream physical fabric. Primary path for all north-south traffic.
Bidirectional Forwarding Detection detects link failure in <200 ms. BGP reconverges and reroutes traffic to the standby edge node.
Data Processing Unit moves packet processing off the host CPU. At 100 Gbps, offload keeps CPU at ~15% vs 98% without it.
A real-time software replica of the physical network. Chaos experiments run here first — before touching production.
Adjust traffic load, toggle DPU offload, then inject chaos. Watch the network react and recover.
Five stages from fault injection to full recovery — each mapped to real NSX-T and BGP primitives.
Primary edge router process is killed. BFD hello packets stop arriving on the peer within the configured interval (300 ms default).
BFD session transitions to DOWN state in <200 ms. Immediately signals the BGP process that the neighbor is unreachable.
BGP withdraws routes learned via the failed peer. Standby edge node's BGP session becomes the active path. Route tables update across the fabric.
Dataplane switches to the standby edge node. Packet flow resumes. Total failover window: 150–300 ms with BFD; up to 90 s without it.
Primary router restarts. BFD re-establishes. BGP re-advertises routes. Traffic load-balances back across both edge nodes.
