Sentence examples for preemptive service from inspiring English sources

As interruptions have a preemptive behavior, we can model the preemptive service discipline as a preemptive-resume queue with N + 1 classes of traffic, the highest priority packets being the virtual packets.

Those results show that the novel priority discipline of preemption in case of failure for OSA networks can significantly improve the system time of HP packets in several deployment scenarios while having a lower implementation complexity than a full preemptive service discipline.

However, due to the preemptive service discipline, the mean number of low-priority customers in the queue, as well as the customer loss probability of the low-priority class are increasing at a greater rate than the corresponding ones for the high-priority class.

Using this alternative approach, it is possible to find approximate results for the preemptive and non-preemptive service disciplines as follows.

However, it can be observed that the system time for the non-preemptive service discipline obtained with the alternative approach presented in Section 5 is not accurate.

Priority service disciplines, such as the preemptive and non-preemptive service disciplines, are the most common approaches to implement service differentiation in communication networks.

For the non-preemptive service discipline, the queue can be modeled as a priority queue where the highest class of traffic (virtual) behaves preemptively, but other classes behave non-preemptively.

As expected, and can also be observed for all the presented results, the HP system time increases from the preemptive, preemptive in case of failure, exceptional non-preemptive and non-preemptive service disciplines, and the LP system time increases in the inverse order of service disciplines.

Queueing models with preemptive priority service discipline and interruptions have been previously studied[7 11].

(1) Increase backoff window sizes to reduce chances of packet collisions; (2) increase carrier sensing range to withstand the effect of hidden terminal; (3) design proper repetitions of the emergency packet within the packet lifetime; (4) give the event-driven safety service preemptive priority over the routine safety service so that possible collisions between two types of service will be reduced.

Table 3 illustrates waiting and service times for preemptive and non-preemptive policies, as the arrivals rates are changed to (.25, 1.25,.5).
