An improved dynamic priority queue for multimedia network communications

We propose an optimizing queue scheme for multimedia network communications with dynamic priority. Arriving users are classified into two types based on their transmission contents, and they are served by different priority degrees. The high priority user (e.g., control messages, video, voice) has higher access possibility than the low priority user (e.g., data). This is realized by adding a dynamic priority to the priority class, instead of a constant priority. After SOR (successive over-relaxation) simulation the results illustrate that the improved dynamic priority queue is efficient to improve the performance of the total system.
