BBC bypasses Linux kernel to make streaming videos flow

Re: Smells funny

They're trying to send uncompressed 4K video over IP (they probably mean UDP/IP). The blog says the data for each stream has got to be generated sequentially using one core, the application which generates it has to be capable of generating enough data to fill 340,000 packets per second, and one packet has to be sent out every 3 microseconds. I suppose it's easier to do that by writing it to a block of memory with the headers in the right place then passing a pointer to the network card driver which just sends it out. There's probably no kind of security whatsoever though.
