| Abstract | In this paper, we propose a novel classifier technique, named short-time burst degradation classifier (SBDC), to improve the short-term delay and the packet jitter for real-time traffic. In the classifier, we manage the traffic to improve the sort-term QoS provisioning in a flexible manner, since traditional mechanisms such as leaky bucket can not have such kind of flexibility. Even though, the proposed scheme is general and can be used in different points of the network, we propose to use it in MPLS ingress nodes. To evaluate the performance of the classifier we propose an efficient scheduler, called short-term quality-of-service class based queuing (SQ-CBQ), to be combined with our classifier. The scheduler uses a new scheduling algorithm named polling deficit round robin (PDRR). Also, after using the combination of the classifier and the scheduler in an MPLS ingress node the impact of short-time scale burstiness of the traffic will be decreased. The performance analysis shows that high quality of service provisioning for the real-time traffic will be achieved. |
