# applicationService

The default parameters for connecting with other, local devices that are running your app.

```
final class var applicationService: NWParameters { get }
```

## Discussion

The default parameters set up an encrypted connection with another device on the local network. You can use these parameters as-is, or you can add a [`NWProtocolFramer`](/documentation/Network/NWProtocolFramer) to provide application-level messaging support.
