| |
Is there a way you can do some sort of priority-based tcp scheduling for ppp? What I would like to have is ftp/wget running at a low priority, http at a higher and telnet at the highest priority, so that if a http packet comes down, all ftp connections stall for a while (i guess this stall would, in general, be a lot longer than required, but that's okay) and then continue. Basically when I'm websurfing, the ftp connections beneath kill the speed over my poor 28.8kbps, and if I cut off all of them I feel guilty for wasting phone time when I'm reading a page or something.
I peeked into kernel:net/sched/ and found one zillion schedulers with weird names like tbf and sfq and another bunch of classifiers, and even something that looked like an API for writing schedulers, all with zilch documentation of course, so I'm sure some sort of support exists in the kernel.
I'm not sure this is perfectly possible (can't control queues on the receiving end and so on), but any sort of improvement over the current scheduling would be beneficial.
Thanks in advance,
