# Policy for extreme traffic

## [📄️Enable extreme high-connection workloads](https://docs.tigera.io/calico-enterprise/3.21/network-policy/extreme-traffic/high-connection-workloads.md)

[Create a Calico network policy rule to bypass Linux conntrack for traffic to workloads that experience extremely large number of connections.](https://docs.tigera.io/calico-enterprise/3.21/network-policy/extreme-traffic/high-connection-workloads.md)

## [📄️Defend against DoS attacks](https://docs.tigera.io/calico-enterprise/3.21/network-policy/extreme-traffic/defend-dos-attack.md)

[Define DoS mitigation rules in Calico Enterprise policy to quickly drop connections when under attack. Learn how rules use eBPF and XDP, including hardware offload when available.](https://docs.tigera.io/calico-enterprise/3.21/network-policy/extreme-traffic/defend-dos-attack.md)
