OSD vs Multicast in CM12R2

[mlbriggs24]

I need to refresh clients in a classroom environment every 3 months to ensure compliance and keep drift under control. I am not sure whether I need to use OSD or Multicast for the deployments. Does anyone have a chart or list of the Pro's and Con's of each?

You can't do Multicast without OSD (Operating System Deployment). In case of a classroom that requires a fresh operating system, I would defenitely try to use multicast. The download of the image file will definitely benifit of this.

Thanks for the response. I've heard that the benefits from a network bandwidth standpoint were only realized when deploying literally hundreds of clients simultaneously. Is this correct?

 

Also, is there a Pro's or Con's list handy showing the differences between OSD and Multicast?

So my questions come down to when to use multicast vs 'deploy an OSD task sequence and make it required'.
