Hoi2 Armageddon Patch 1.3. Published: April 27, 2016 Applies To: Windows Server 2016 Standard Technical Preview 5, Windows Server 2016 Datacenter Technical Preview 5, Windows Server Update Services Background Intelligent Transfer Service (BITS) uses idle network bandwidth to perform prioritized, throttled, asynchronous file transfers. Windows Update, Windows Server Update Services (WSUS), and Systems Management Server use BITS to efficiently deliver software updates to clients. Dvb-t Mac Drivers more.

Windows Defender uses BITS when fetching signature updates, and Microsoft's instant messaging products use BITS to transfer files. Background transfers are optimal in that BITS uses idle network bandwidth to transfer the files and will increase or decrease the rate at which files are transferred based on the amount of idle network bandwidth available.

If a network application begins to consume more bandwidth, BITS decreases its transfer rate to preserve the user's interactive experience. BITS continues to transfer files after an application exits if the user who initiated the transfer remains logged on and a network connection is maintained. If a connection is lost or if the user logs off, BITS suspends the transfer. BITS transfer information persists while the user is logged off, if network connectivity is interrupted, and during computer restarts.

When the user logs on again, and network connectivity is restored, BITS resumes the user's transfer job. BITS constantly monitors for any increase or decrease in network traffic and adjusts the transfer rates of BITS jobs to ensure that other foreground applications, such as a web browser, get the bandwidth they need. If applications are using 85 percent of the available network bandwidth, BITS will use only the remaining 15 percent. BITS uses a best-effort estimate of bandwidth usage. BITS versions 3.0 and subsequent versions use Internet Gateway Device counters, if available, to more accurately calculate available bandwidth. Otherwise, BITS uses the speed reported by the network interface card (NIC) to calculate bandwidth. Estimates based on the speed reported by the NIC can cause bandwidth calculation errors, when a fast network adapter is connected to the network over a slow link.

BITS uses a queue to manage file transfer sessions. A session is started when an application creates a job, which is a container that has one or more files to transfer. While a download job can have any number of files, upload jobs can have only one. Properties can be set for individual files. Jobs inherit the security context of the application that created them. BITS provides API access to control jobs.
