Constructing end-to-end paths for playing media objects
نویسندگان
چکیده
This paper describes a framework for constructing network services for accessing media objects. The framework, called end-to-end media paths, provides a new approach for building multimedia applications from component pieces. Based on input from the user and resource requirements from the media object, the system first discovers the sequence of nodes (end-to-end path) that both connect the source device to the sink device and possess sufficient resources to play the object. It then configures the individual nodes along this path with the modules (path segment) that implement the service.

Towards a Distributed Quality of Service Handler for Multimedia Presentations
Distributed multimedia presentation, involving different media objects on different servers, must strictly follow its defined temporal scenario. Out of synchronization is a fundamental problem in case of distributed multimedia. In this paper, we introduce a distributed QoS handler, whose aim is to distribute the QoS adaptation tasks among all the servers holding the media object. In this case, ...
متن کاملFinding Service Paths in an Overlay Media Service Proxy Network
An overlay media service proxy network is formed by a set of multimedia service proxies deployed at strategic locations in the underlying network. Proxies in this overlay network are able to provide applicationlevel media services, such as media data transcoding and analysis. End points of multimedia communication can then connect to this network, and request a combination of media services del...
متن کاملRate-distortion Optimized Packet Scheduling and Routing for Media Streaming with Path Diversity
We consider diversity for media streaming in a rate-distortion optimization framework. A sender-driven transmission scenario is investigated, where diversity is achieved by using multiple transmission paths over the network. The proposed framework enables the sender to decide at every instant which packets, if any, to transmit and over which transmission paths in order to meet a rate constraint...
متن کاملReducing End-to-End Delay in Multi-path Routing Algorithms for Mobile Ad Hoc Networks
Some of the routing algorithms in mobile ad hoc networks use multiple paths simultaneously. These algorithms can attempt to find nodedisjoint paths to achieve higher fault tolerance capability. By using nodedisjoint paths, it is expected that the end-to-end delay in each path should be independent of each other. However, because of natural properties of wireless media and medium access mechanis...
متن کاملModeling and Emulation of Internet Paths
Network emulation subjects real applications and protocols to controlled network conditions. Most existing network emulators are fundamentally link emulators, not path emulators: they concentrate on faithful emulation of the transmission and queuing behavior of individual network hops in isolation, rather than a path as a whole. This presents an obstacle to constructing emulations of observed I...
