Abstract *
While there is currently great interest in the problem of
providing real­time services in general purpose operating
systems, the issue of real­time scheduling of internal oper­
ating system activities has received relatively little atten­
tion. Without such real­time scheduling, the system is
susceptible to conditions such as receive livelock --- a
situation in which an operating system spends all its time
processing arriving network packets, and application proc­
esses, even if scheduled with a real­time scheduler, are
starved. We investigate the problem of scheduling operat­
