這個原則設定會定義系統連線到成本已評估網路 (3G 等) 時,背景智慧型傳送服務用於背景傳送的預設行為。下載行為原則會更進一步限制背景傳送的網路使用量。
如果您啟用這個原則設定,您可以為每個 BITS 工作優先順序定義預設下載原則。這個設定不會覆寫由建立 BITS 工作之應用程式明確設定的下載原則,不過會套用到建立時只有指定優先順序的工作。
例如,您可以在預設值指定只在非成本已評估網路連線上傳送背景工作,但是前景工作只能在不是漫遊的情況下進行傳送。可以指派的值如下:
- 一律傳送
- 漫遊時不傳送
- 需要額外付費時不傳送 (沒有漫遊或超出容量)
- 接近容量限制時不傳送 (沒有漫遊或接近容量限制)
- 只有在沒有限制時傳送
- 自訂--讓您指定位元遮罩,其中的位元說明此優先順序允許或不允許的成本狀態: (下列為位元的說明)
0x1 - 成本不明或連線不受限制,沒有使用費和容量的限制。
0x2 - 這個連線的使用量到達某個資料限制之前,不會加以限制
0x4 - 這個連線的使用量到達某個資料限制之前,不會加以限制,而且計畫使用量低於限制的 80%。
0x8 - 這個連線的使用量到達某個資料限制之前,不會加以限制,而且計畫使用量介於限制的 80% 和 100% 之間。
0x10 - 這個連線的使用量到達某個資料限制之前,不會加以限制,目前已超過限制。需支付額外費用或不明。
0x20 - 這個連線的使用量到達某個資料限制之前,不會加以限制,目前已超過限制。不需支付額外費用,但速度會減慢。
0x40 - 連線計價方式是以位元組為單位。
0x80 - 漫遊連線。
0x80000000 - 忽略壅塞。
