Android unterstützt 5G-Netzwerk-Slicing, die Verwendung von Netzwerkvirtualisierung, um einzelne Netzwerkverbindungen in mehrere verschiedene virtuelle Verbindungen aufzuteilen, die verschiedenen Arten von Traffic unterschiedliche Ressourcen zur Verfügung stellen.
Für jede ApplicationPolicy kann ein preferentialNetworkId angegeben werden, um den Traffic zu einem bestimmten Slice weiterzuleiten. Wenn kein Wert angegeben ist, wird stattdessen defaultPreferentialNetworkId verwendet.
Mit fallbackToDefaultConnection wird konfiguriert, ob die Standardverbindung (z.B. allgemeines Mobilfunknetz oder WLAN) verwendet wird, wenn keine bevorzugte Netzwerkdienstverbindung verfügbar ist.
Für 5G-Netzwerk-Slicing ist keine Anwendungsunterstützung erforderlich. Der Netzwerkverkehr wird basierend auf der Konfiguration weitergeleitet. Anwendungen können weiterhin explizit ein anderes Netzwerk auswählen, es sei denn, NON_MATCHING_NETWORKS_DISALLOWED ist festgelegt.
Ab Android 12 können IT-Administratoren mit preferentialNetworkService den Traffic für alle im Arbeitsprofil ausgeführten Anwendungen an ein festes Netzwerksegment des Unternehmens weiterleiten. Ab Android 13 können IT-Administratoren preferentialNetworkService auch auf vollständig verwalteten Geräten verwenden.
Unter Android 13 und höher können IT-Administratoren mit preferentialNetworkServiceSettings bis zu fünf bevorzugte Netzwerke aktivieren und Apps einem bestimmten Netzwerk zuweisen.

Add networks you want to enable to\n[`preferentialNetworkConfigs`](https://developers.google.com/android/management/reference/rest/v1/enterprises.policies#PreferentialNetworkServiceSettings).\n\nEach [`ApplicationPolicy`](https://developers.google.com/android/management/reference/rest/v1/enterprises.policies#ApplicationPolicy) can specify a [`preferentialNetworkId`](https://developers.google.com/android/management/reference/rest/v1/enterprises.policies#ApplicationPolicy.FIELDS.preferential_network_id) to route\ntraffic to a specific slice. If no value is specified, the\n[`defaultPreferentialNetworkId`](https://developers.google.com/android/management/reference/rest/v1/enterprises.policies#PreferentialNetworkServiceSettings) will be used instead.\n[`fallbackToDefaultConnection`](https://developers.google.com/android/management/reference/rest/v1/enterprises.policies#FallbackToDefaultConnection) configures whether the default connection (e.g.\ngeneral cell network or wifi) is used if no preferential network service\nconnection is available.\n\nYou can configure apps not to use preferential network by setting\n[`preferentialNetworkId`](https://developers.google.com/android/management/reference/rest/v1/enterprises.policies#ApplicationPolicy.FIELDS.preferential_network_id) to [`NO_PREFERENTIAL_NETWORK`](https://developers.google.com/android/management/reference/rest/v1/enterprises.policies#PreferentialNetworkId).\n\n### Application support\n\n5G network slicing does not require application support, network traffic will be\nrouted based on the configuration. Applications can still explicitly select a\ndifferent network, unless [`NON_MATCHING_NETWORKS_DISALLOWED`](https://developers.google.com/android/management/reference/rest/v1/enterprises.policies#NonMatchingNetworks) is set.\n\nEnterprise preferential networks map to [`NetworkCapabilities`](https://developer.android.com/reference/android/net/NetworkCapabilities); Specifically\n[`NET_ENTERPRISE_ID_1`](https://developer.android.com/reference/android/net/NetworkCapabilities#NET_ENTERPRISE_ID_1) through [`NET_ENTERPRISE_ID_5`](https://developer.android.com/reference/android/net/NetworkCapabilities#NET_ENTERPRISE_ID_5) map to\n[`PREFERENTIAL_NETWORK_ID_ONE`](https://developers.google.com/android/management/reference/rest/v1/enterprises.policies#PreferentialNetworkId) through [`PREFERENTIAL_NETWORK_ID_FIVE`](https://developers.google.com/android/management/reference/rest/v1/enterprises.policies#PreferentialNetworkId).\n| **Key Point:** The default network applies to all installed applications on work profile or all applications on fully managed devices, not just the ones specified in the policy.\n\n### Version support\n\nStarting from Android 12, IT Admins can use [`preferentialNetworkService`](https://developers.google.com/android/management/reference/rest/v1/enterprises.policies#PreferentialNetworkService) to\nroute traffic for all applications running in the Work Profile to a fixed\nenterprise network slice. Starting with Android 13, IT Admins can use\n[`preferentialNetworkService`](https://developers.google.com/android/management/reference/rest/v1/enterprises.policies#PreferentialNetworkService) on fully managed devices as well.\n\nOn Android 13 and later, IT Admins can use\n[`preferentialNetworkServiceSettings`](https://developers.google.com/android/management/reference/rest/v1/enterprises.policies#deviceconnectivitymanagement) to enable up to 5 preferential networks\nand assign applications to a specific network.\n| **Important:** If both `preferentialNetworkServiceSettings` and `preferentialNetworkService` are set, `preferentialNetworkServiceSettings` takes precedence on Android 13 and later.\n\nExample policy\n--------------\n\n {\n \"applications\": [\n {\n \"packageName\": \"com.example.one\",\n \"installType\": \"AVAILABLE\",\n \"preferentialNetworkId\": \"PREFERENTIAL_NETWORK_ID_TWO\"\n },\n {\n \"packageName\": \"com.example.two\",\n \"installType\": \"AVAILABLE\",\n \"preferentialNetworkId\": \"PREFERENTIAL_NETWORK_ID_THREE\"\n }\n ],\n \"deviceConnectivityManagement\": {\n \"preferentialNetworkServiceSettings\": {\n \"defaultPreferentialNetworkId\": \"PREFERENTIAL_NETWORK_ID_TWO\",\n \"preferentialNetworkServiceConfigs\": [\n {\n \"preferentialNetworkId\": \"PREFERENTIAL_NETWORK_ID_TWO\",\n },\n {\n \"preferentialNetworkId\": \"PREFERENTIAL_NETWORK_ID_THREE\",\n }\n ]\n }\n }\n }\n\n| **Important:** Critical applications are excluded from [`defaultPreferentialNetworkId`](https://developers.google.com/android/management/reference/rest/v1/enterprises.policies#PreferentialNetworkServiceSettings), check the documentation for more details. You can still configure their network by using the [`Application.preferentialNetworkId`](https://developers.google.com/android/management/reference/rest/v1/enterprises.policies#ApplicationPolicy.FIELDS.preferential_network_id) setting.\n| **Tip:** Networks that have no installed applications assigned to them will be silently ignored on the device."]]
