# InFlightConn
Limiting the Number of Simultaneous connections.
{: .subtitle }
To proactively prevent services from being overwhelmed with high load, the number of allowed simultaneous connections by IP can be limited.
## Configuration Examples
```yaml tab="Docker"
labels:
- "traefik.tcp.middlewares.test-inflightconn.inflightconn.amount=10"
```
```yaml tab="Kubernetes"
apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
name: test-inflightconn
spec:
inFlightConn:
amount: 10
```
```yaml tab="Consul Catalog"
# Limiting to 10 simultaneous connections
- "traefik.tcp.middlewares.test-inflightconn.inflightconn.amount=10"
```
```json tab="Marathon"
"labels": {
"traefik.tcp.middlewares.test-inflightconn.inflightconn.amount": "10"
}
```
```yaml tab="Rancher"
# Limiting to 10 simultaneous connections.
labels:
- "traefik.tcp.middlewares.test-inflightconn.inflightconn.amount=10"
```
```yaml tab="File (YAML)"
# Limiting to 10 simultaneous connections.
tcp:
middlewares:
test-inflightconn:
inFlightConn:
amount: 10
```
```toml tab="File (TOML)"
# Limiting to 10 simultaneous connections
[tcp.middlewares]
[tcp.middlewares.test-inflightconn.inFlightConn]
amount = 10
```
## Configuration Options
### `amount`
The `amount` option defines the maximum amount of allowed simultaneous connections.
The middleware closes the connection if there are already `amount` connections opened.
