With the prevalence of personal computer devices and the Internet, a multimedia server has to perform video transcoding to serve users under heterogeneous network environments. In this paper, we propose a stability-driven hierarchical scheduling algorithm for the cloud-based video streaming system to speed up the video transcoding process for real-time service applications. The Multi-layer Division of the Max-MCT schedulingalgorithm (MDMCT) has been developed to reduce the convoy effect. It helps to coordinate the system operations and dynamically adjust the number of slots so that the cloud cluster-s can finish the process more efficiently. Experimental result-s show that the proposed scheduling control method helps to maintain good system load balancing. The resources utilization of the entire cloud clusters can be maintained at about 98%, and the processing time can be reduced by about 13.4%.

With much more advanced techniques employed, various applications can be supported by 3G CDMA-based wireless networks. Providing differentiated service over wireless networks has become a very important issue in the design of wireless networks. A new media access control protocol with a hierarchical scheduling algorithm to provide differentiated service for CDMA-based wireless networks is proposed. This protocol evolves from the distributed queuing random access protocol for CDMA wireless network. The proposed protocol has been designed to have an ability to accommodate integrated traffic in the networks with effective scheduling schemes. A series of simulation experiments have been carried out to evaluate the performance of the proposed protocol with the hierarchical scheduling algorithm. The results reveal that the proposed solution performs effectively in the integrated traffic composed of messages with or without time constraints and achieves proportional fairness among different types of traffic.
A hierarchicalscheduling concept is proposed to provide both a QoS guarantee and enhanced switching throughput in a multiple input-queued switch under bursty environment conditions.
