“…A new approach combined WFQ with LLQ scheduling disciplines to ensure QoS for high priority bursty video conferencing, voice and data services at the same time [7]. The main drawback of the WFQ with LLQ is that we get reduced delay of high priority class (video conferencing) but at the same time we get highest delay time of voice traffic.…”

“…The main drawback of the WFQ with LLQ is that we get reduced delay of high priority class (video conferencing) but at the same time we get highest delay time of voice traffic. In another study, Brunonas et al [7] proposed a new approach by combining WFQ with LLQ scheduling disciplines to ensure QoS for high priority bursty video conferencing, voice and data services at the same time. The main weakness of the WFQ with LLQ is that although there is reduced delay of high priority class (video conferencing), there is highest delay time of voice traffic.…”

An Enhanced Low Latency Queue scheduling algorithm that categorizes and prioritizes the realtime traffic was developed. In this algorithm the high priority queues are introduced for scheduling the video applications separately along with the voice applications, with voice applications having a higher priority over video applications. The low priority queues are serviced using Class Based Weighted Fair Queueing. However, at high arrival rate of voice packets, the video packets may suffer resource starvation. To overcome this drawback, we propose an improved LLQ algorithm which delays voice packets that arrive while the video packets are already in the queue and services video packets found in the queue before servicing voice packets as long as the voice packets are not delayed beyond the maximum tolerable delay limit. MAT-LAB software is used to plot the graphs. This study discovers the possible ways of reducing the delay experienced by voice packets without over penalizing the video packets. This study will help researchers to uncover possible ways of providing the quality of service to various classes of traffic. Numerical results obtained from the derived models show that delaying voice packets leads to reduction in the average waiting time of video packets. Furthermore, voice packets can be delayed to serve video packets as long as the load and arrival rates of voice packets does not exceed 81% and 14 packets/second respectively and less dependent on the load and arrival rates of video packets.

Providing Quality of Service in the Internet is a complex and multilevel problem involving heterogeneous media, protocols and technologies. The ability to differentiate traffic will allow introducing QoS oriented business relationships and pricing models, supported by the establishment of Service Level Agreements (SLAs.) Recent developments within the research community and within commercial products provide numerous technologies that may be applied as solutions. In this paper we are proposing the new adaptive (AFQ) scheduling for SLA QoS management model for differentiated services , reasoned by the virtual queue and dynamic weighted queues service coefficient φ, changing according to the evaluation of the packet state in the node, reasoned by delay target time and present network load.

Abstract-The reliability indexes is the very important link for guaranteeing the precision, function, using life span for mechanical equipment. The paper introduces the fuzzy factor of fuzzy assessment for the reliability check and index in the light of the typical model of machinery equipment fuzzy appraise synthesis method. The appraising model and subordinate function and weigh proportion are built after analysis. The evidence is supplied with the reliability design for the new products through fuzzy appraising example. The result shows that the proposed evaluation model is reasonable and feasible，which can objectively reflect the overall level of mechanical equipment reliability.
