rate-monotonic scheduling[1] is a scheduling algorithm used in real-time operating systems with a static-priority scheduling class.[2] The static priorities are assigned on the basis of the cycle duration of the job: the shorter the cycle duration is

Service prioritization among different traffic classes is an important goal for the Internet. Conventional approaches to solving this problem consider the existing best-effort class as the low-priority class, and attempt to develop mechanisms that pr
