Use ipxe + peerdist option (BranchCache) + wimboot?

Hi Robin,

currently I'm working on a workflow to automatically detect PXE attacks in an network. Therefore I was writing my own Bootloader which manages to notice this kind of attacks and does some more things. After the bootloader did his job I have to start a WINPE. The reason i have to use wimboot ist that the normal tftp download ist to slow for bigger scaling networks. Lets say i want to start 20000 WINPE at the same time I will get a big problem if i would use TFTP. So i want to use wimboot because its http download has a better performance.
It would also help me if you know if i could use ipxe to solve this problem?

Thanks for your help

Why are you even doing this, when ipxe+wimboot already does what you
want? See ipxe.org/howto/winpe or ipxe.org/howto/sccm and
ipxe.org/appnote/wimboot_architecture for details on how they work.

Please feel free to elaborate why/if the current ipxe+wimboot doesn't
work for you and your situation.
