Lưu và phân loại nội dung dựa trên lựa chọn ưu tiên của bạn.
Android hỗ trợ cắt mạng 5G, sử dụng tính năng ảo hoá mạng để chia một kết nối mạng thành nhiều kết nối ảo riêng biệt, cung cấp nhiều lượng tài nguyên cho nhiều loại lưu lượng truy cập.
Tính năng phân đoạn mạng 5G không yêu cầu ứng dụng hỗ trợ, lưu lượng truy cập mạng sẽ được định tuyến dựa trên cấu hình. Các ứng dụng vẫn có thể chọn một mạng khác một cách rõ ràng, trừ phi bạn đặt NON_MATCHING_NETWORKS_DISALLOWED.
Kể từ Android 12, Quản trị viên CNTT có thể sử dụng preferentialNetworkService để định tuyến lưu lượng truy cập cho tất cả ứng dụng chạy trong Hồ sơ công việc đến một lát cắt mạng doanh nghiệp cố định. Kể từ Android 13, Quản trị viên CNTT cũng có thể sử dụng preferentialNetworkService trên các thiết bị được quản lý toàn diện.
Trên Android 13 trở lên, Quản trị viên CNTT có thể sử dụng preferentialNetworkServiceSettings để bật tối đa 5 mạng ưu tiên và chỉ định ứng dụng cho một mạng cụ thể.

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."]]
