Integrated Admission Control in Hierarchical Video-on-Demand Systems
نویسندگان
چکیده
In this paper, we develop a unified model of a hierarchical Video-on-Demand(VoD) system by integrating the storage and the network subsystems. Rather than restricting the analysis to an isolated subsystem the performance of the VoD system is analyzed as an end-to-end system. On a system-wide basis, request handling and admission control policies are designed to minimize global performance metrics. Through our simulation, we compare different request handling policies and show that a hierarchical VoD architecture with request handling that allows retrials at more than one resource will minimize overall blocking.

Fuzzy Hierarchical Location-Allocation Models for Congested Systems
There exist various service systems that have hierarchical structure. In hierarchical service networks, facilities at different levels provide different types of services. For example, in health care systems, general centers provide low-level services such as primary health care services, while the specialized hospitals provide high-level services. Because of demand congestion in service networ...

On-demand video servers based on hierarchical storage systems are able to ooer high-capacity and low-cost video storage. In such a system, video les are stored in the tertiary level and transferred to the secondary level to be displayed. The design of video servers allowing user interaction with the playbacked video is of great interest. We have conducted a comprehensive study on the architectu...

متن کاملA Hierarchical Video-on-Demand System for ATM Networks
Video-on-Demand (VOD) is expected to be the key residential service in the near future. A VOD system consists of three components: the VOD server, the transport network, and the end user. In this paper, we focus on the design of the network module of a VOD system. We propose a hierarchical VOD network structure which can be used to achieve a low cost, high performance, high scalability, and hig...
متن کاملThreshold-based Admission Control for Multi-class Video-on-demand Systems
The next generation of distributed digital Video-onDemand (VoD) systems will use admission control tests to ensure that users receive predictable and guaranteed service. If the system cannot support a new request then that request blocks. This paper presents an analytical model to evaluate unified admission control strategies for distributed VoD systems with multiple video classes. We prove tha...
