UDP & TCP Flooder — High-Volume Layer 4 Stress Testing
Benchmark router switching capacity, firewall connection tracking tables, and anti-DDoS scrubbing appliances with high-density UDP and TCP packet floods.
Boota vs Basic UDP Flood Scripts
| Feature / Capability | Boota Platform | Basic UDP Flood Scripts |
|---|---|---|
| Amplification Reflection Vectors | Verified clean reflector pools (DNS, NTP, CLDAP) | Unamplified direct UDP only |
| TCP State Exhaustion (SYN/ACK/RST) | Full TCP state-machine fuzzing | Basic SYN flood only |
| Packet Size Customization | Configurable MTU and payload size (64 to 1500 bytes) | Fixed payload size |
| Real-time Mpps Monitoring | Live packet rate counters & dstat feeds | No packet tracking |
Testing Stateful Firewalls and NAT Table Exhaustion
Stateful firewalls and load balancers must maintain an entry in their connection tracking table (conntrack) for every active TCP connection and UDP flow. When bombarded with millions of unique packets per second, these tables exhaust their allocated kernel memory, causing all subsequent connections — including legitimate traffic — to be dropped. Boota allows you to test and optimize your conntrack table sizes and timeout parameters.
- Tune Linux `net.netfilter.nf_conntrack_max` and timeout sysctls.
- Validate firewall SYN cookie (`tcp_syncookies`) activation under extreme loads.
- Verify edge scrubbing center failover SLAs under multi-hundred Gbps bursts.
Frequently Asked Questions
How do amplification attacks work in testing?
Amplification vectors exploit protocols (like DNS or NTP) that send large responses to small queries, multiplying the effective bandwidth delivered to the target to test edge scrubbing capacity.
