I am sure someone could make the argument that if the cache were designed
suitably, it wouldn't need to send out packets because it wouldn't die in
the first place. Or further, wouldn't need load balancing from a switch
because it would have a suitable mechanism of capacity planning the
traffic itself.
I can think of an example where the disk might partially fail and WCCP
packets would still be sent out.
But of course, no one implements technology today before its been
thoroughly matured with a million years of uptime.
