QoS design is the fundamental functionality of the next generation IP router to enable differentiated delivery and to guarantee the delivery quality for diverse service traffic. The proposed algorithm called adaptive weighted fair queue (AWFQ) scheduling employs the queue status and priority assignment to determine the bandwidth sharing of various Internet services and to ensure the defined QoS policy is obtained. We propose a smart methodology of distributing the outlink bandwidth in a flexible, fair and prioritized manner to utilize network bandwidth more effectively and efficiently. In simulation, we compare the proposed AWFQ algorithm with priority queue (PQ) and weighted fair queue (WFQ) that are two famous scheduling algorithms in practice. In comparison, we examine their performances in terms of packet loss, bandwidth utilization and queue dynamics to verify our algorithm. We find that the proposed algorithm has the following advantages: 1) improves the bandwidth starvation of low-priority traffic occurring in PQ, 2) has a high bandwidth utilization close to PQ, 3) has a low queue congestion and 4) maintains the fairness of WFQ. Overall, the proposed algorithm not only has an excellent performance close to PQ but also improve the disadvantage of PQ.","PeriodicalId":358168,"journal":{"name":"Proceedings of IEEE Region 10 International Conference on Electrical and Electronic Technology.

The current cache system employs a hard strategy: either the image is stored in a cache or not, even if its data is quite big. We have proposed a caching scheme featuring a human memory mechanism (image database system featuring graceful oblivion), which is called graceful caching. Previous work shows that graceful caching reduces user response time by assigning a variable amount of memory to each image. Several recent studies suggest that prefetching techniques could be employed to further improve the cache performance, by anticipating and prefetching future client requests. Some approaches based on request frequency have been proposed to the conventional caching (hard system) and got better results. We try to apply a request frequency-based approach to the graceful caching system, in which a progressive image format is used. Based on the analysis of Web request probability in graceful caching, we go on to propose a new prefetching algorithm that drastically improves the cache performance of the system. We verify the performance of this algorithm by simulations.","PeriodicalId":358168,"journal":{"name":"Proceedings of IEEE Region 10 International Conference on Electrical and Electronic Technology.
