Van Jacobson's network channels -- Microkernel?Van Jacobson's network channels -- Microkernel?Posted Feb 1, 2006 20:48 UTC (Wed) by JoeBuck (subscriber, #2330)In reply to: Van Jacobson's network channels -- Microkernel? by NAR Parent article: Van Jacobson's network channels It's not really so surprising. The cost being avoided in both cases is context switching. The default way of doing things is that the lower-level processing is in the kernel and the higher-level processing is in userspace. Either moving almost everything into the kernel, or moving almost everything out, reduces the overhead.
