Android supporta lo slicing della rete 5G, ovvero l'utilizzo della virtualizzazione della rete per suddividere le singole connessioni di rete in più connessioni virtuali distinte che forniscono quantità diverse di risorse a diversi tipi di traffico.
Ogni ApplicationPolicy può specificare un preferentialNetworkId per indirizzare il traffico a una frazione specifica. Se non viene specificato alcun valore, verrà utilizzato defaultPreferentialNetworkId.
fallbackToDefaultConnection consente di configurare se utilizzare la connessione predefinita (ad es. rete mobile generale o Wi-Fi) se non è disponibile una connessione di servizio di rete preferenziale.
Lo slicing della rete 5G non richiede il supporto delle applicazioni, il traffico di rete verrà indirizzato in base alla configurazione. Le applicazioni possono comunque selezionare esplicitamente un'altra rete, a meno che non sia impostato NON_MATCHING_NETWORKS_DISALLOWED.
A partire da Android 12, gli amministratori IT possono utilizzare preferentialNetworkService per indirizzare il traffico di tutte le applicazioni in esecuzione nel profilo di lavoro a uno slice della rete aziendale fisso. A partire da Android 13, gli amministratori IT possono utilizzare
preferentialNetworkService anche sui dispositivi completamente gestiti.
Su Android 13 e versioni successive, gli amministratori IT possono utilizzare
preferentialNetworkServiceSettings per attivare fino a 5 reti preferenziali
e assegnare le applicazioni a una rete specifica.

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."]]
