Use multicast to deploy Windows over the network with System Center Configuration Manager

Applies to: System Center Configuration Manager (Current Branch)

Multicast is a network optimization method that you can use in your System Center Configuration Manager environment where multiple clients are likely to download the same operating system image at the same time. When multicast is used, multiple computers simultaneously download the operating system image as it is multicast by the distribution point, rather than having the distribution point send a copy of the data to each client over a separate connection.

You can deploy operating systems over the network by using multicast in the following operating system deployment scenarios:

Configure a distribution point to support multicast

To use multicast when you deploy operating systems, you must configure a distribution point to support multicast. For more information, see Install and configure distribution points. For a list of ports required to support multicast, see Ports.

Prepare an operating system image for multicast deployments

To configure the operating system image package to support multicast, see Prepare the operating system image for multicast deployments.

Deploy the task sequence

Deploy the operating system to a target collection. For more information, see Deploy a task sequence.
