Algorithmic Background of the Host Recommendation in the Adaptive Distributed Multimedia Server
نویسندگان
چکیده
In a distributed server architecture an obvious question is where to deploy the components. Host recommendation, which gives the answer, faces problems such as server selection, host deployment and, in case of multimedia servers, video replication. It is especially relevant for the Adaptive Distributed Multimedia Server (ADMS) which is dynamically able to add and remove its components to different nodes of the network. The present survey paper introduces the different variants of host recommendation and gives an overview of its possible mathematical approaches. Emphasis is put on the facility location problem and the related approximation algorithms. Finally some algorithms selected for implementation are presented.

Placement of Nodes in an Adaptive Distributed Multimedia Server
Multimedia services typically need not only huge resources but also a fairly stable level of Quality of Services. This requires server architectures that enable continuous adaptation. The Adaptive Distributed Multimedia Server (ADMS) of the University Klagenfurt is able to dynamically add and remove nodes to the actual configuration, thus realizing the offensive adaptation approach. This paper ...
متن کاملCooperating Intelligent Mobile Agents Mechanism for Distributed Multimedia Synchronization
With the developing of the distributed multimedia system, there are many researches focus on how to reduce the network traffic and how to initialize and gather the distributed multimedia resource. In this paper, we propose a robust system using Intelligent Mobile Agents to construct an automatic and adaptation mechanism for distributed multimedia synchronization. Furthermore, an adaptive Qualit...
متن کاملA Distributed Approach to Retrieving JPEG Pictures in Portable Hypermedia Documents
In this paper, we single out one of the problem aspects of multimedia: how can one efficiently store high-quality picture information in a manner that does not make its retrieval characteristics incompatible with the needs of a (distributed) multimedia application. These needs include: timely access to data, predictable access to common (i.e., network) resources and ease in user specification o...
متن کاملTowards an Adaptive Distributed Multimedia Streaming Server Architecture Based on Service-Oriented Components
This paper presents an adaptive distributed multimedia streaming server architecture (ADMS) which explicitly controls the serverlayout. It consists of four types of streaming server components, which all provide dedicated services in an arbitrary number of instances on an arbitrary number of server hosts. Vagabond2 is used as the underlying middleware for component adaptation. It is shown, how ...
متن کاملAdaptive call admission control and resource allocation in multi server wireless/cellular network
The ever increasing demand of the subscribers has put pressure on the capacity of wireless networks around the world. To utilize the scare resources, in the present paper we propose an optimal allocation scheme for an integrated wireless/cellular model with handoff priority and handoff guarantee services. The suggested algorithm optimally allocates the resources in each cell and dynamically adj...
