An idea I've been toying with for a while now is completely abstracting congestion control. Then you could have congestion control loadable modules, which would avoid this mess of experimental algorithms inside the main-line kernel. If done right, they might be able to work seamlessly with SCTP, too. The tricky part is making sure the interface is complete enough. -John - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
