1. If you are talking about WDT image download, we have Multicast download solution for years, maybe you can check with Diag team, we worked with them before.2. If you are talking about PXE boot, multicast, we do not have it right now, but what is the reason you are asking a Multicast download for PXE download? Can you share your insight on this? Why? What is your pain point?Frankly speaking, I am not intending to discuss(learn) any technical solution detail with you(factory end) right now, but try to learn your pain point at the first place… and I do not think multiple PXE download could save more network bandwidth also…Maybe , can we start with my questions please?
