Odyssey: a high-performance clustered video server
نویسندگان
چکیده
Video servers are essential in Video-on-Demand and other multimedia applications. In this paper, we present our high-performance clustered CBR video server, Odyssey. Odyssey is a server connecting PCs with switched Ethernet. It provides efficient support for normal play and interactive browsing functions such as fast-forward and fast-backward. We designed a set of algorithms for scheduling, synchronization, and admission control, which results in a high utilization of resources. Odyssey is able to deliver a large number of video streams. keywords— video content retrieval, clustered video servers, real-time scheduling, Quality-of-Service, interactive browsing operations.

Design and Implementation of a Low-cost Clustered Video Server Using a Network of Personal Computers
Video-on-Demand systems will be the video rental shops of the future. One of the great challenges in VoD domain is to optimize the cost/performance ratio of the designed system. In this paper we present a clustered, high performance, high availability and low cost VoD system, which is based on a network of personal computers. We experimented with state-of-the-art video compression algorithms li...
متن کاملInvestigation on Reliability Estimation of Loosely Coupled Software as a Service Execution Using Clustered and Non-Clustered Web Server
Evaluating the reliability of loosely coupled Software as a Service through the paradigm of a cluster-based and non-cluster-based web server is considered to be an important attribute for the service delivery and execution. We proposed a novel method for measuring the reliability of Software as a Service execution through load testing. The fault count of the model against the stresses of users ...
متن کاملA request distribution method for clustered VOD servers considering buffer sharing effects
The clustering of multiple video servers is a popular architecture for huge VOD systems. In a clustered VOD system, user requests are distributed among the video servers by the dispatcher. Each video server consists of independent disks and a local buffer memory. The buffer mechanism is recognized helpful to the improvement of the disk performance. However, its effects have not been effectively...
متن کاملTransmitting Variable-Bit-Rate Videos on Clustered VoD Systems
Due to the burstiness, scheduling VBR streams and yet achieving high resources utilization on a clustered video server has been considered a difficult problem. In this paper, we propose a simple but effective VBR scheduling algorithm for generating conflict-free network transmission schedules on clustered VoD systems. Experimental results show that this novel scheduling algorithm can achieve ne...
متن کاملA new distributed storage scheme for cluster video server
For cluster video servers, it is very important to design a good distributed storage system with high performance. One of the important issues in designing a good distributed storage system is how to store multimedia data on many storage nodes. This issue includes two topics: the scheme of splitting an entire file into many clips, and the storage of these clips on many nodes. We have designed a...
