# XblMultiplayerPeerToHostRequirements

Represents requirements for each connection between a host candidate and session members.

## Syntax

```cpp theme={null}
typedef struct XblMultiplayerPeerToHostRequirements {  
    uint64_t LatencyMaximum;  
    uint64_t BandwidthDownMinimumInKbps;  
    uint64_t BandwidthUpMinimumInKbps;  
    XblMultiplayerMetrics HostSelectionMetric;  
} XblMultiplayerPeerToHostRequirements  
```

### Members

*LatencyMaximum*\
Type: uint64\_t

The maximum latency, in milliseconds, of the upstream (peer-to-host) connection.

*BandwidthDownMinimumInKbps*\
Type: uint64\_t

The minimum bandwidth, in kilobits per second, of the downstream (host-to-peer) connection.

*BandwidthUpMinimumInKbps*\
Type: uint64\_t

The minimum bandwidth, in kilobits per second, of the upstream (peer-to-host) connection.

*HostSelectionMetric*\
Type: [XblMultiplayerMetrics](/reference/live/xsapi-c/multiplayer_c/enums/xblmultiplayermetrics)

The metric used to select the host.
