Embodiment Construction

[0026] as attached figure 1 As shown in the example of , in a digital home network (IHDN), different applications 1a, 1b, 1c compete for resources. The example concerns a radio network according to the IEEE 802.11b standard. The network includes for example a television 1a (in the kitchen), a computer 1b and a hi-fi device 1c. The applications 1a, 1b, 1c receive their data streams from the family profile 2. A network 5 supporting Quality of Service (QoS), in particular priority-based QoS, exists between the home profile 2 and the applications 1a, 1b, 1c. For radio networks according to IEEE 802.11b, this is basically a priority class for supporting IEEE 802.11e. However, similarly, IEEE802.15.3 or home plug 1 may be used. An exception occurs where the application itself must implement QoS when the network itself does not provide QoS.

[0027] The applications 1a, 1b, 1c require the necessary data streams from the QoS prioritizer 3 jointly conveying their QoS requirements....

Abstract

The invention relates to a method of handling capacity bottlenecks in digital networks, particularly digital home networks, in which at least two apparatuses or applications with public interfaces for influencing the internal resource allocation in a system have access to the resources of a data transfer medium having a non-constant bandwidth. In the case of a resource bottleneck, the data transfer rate of that data stream is reduced whose effect on the associated application is least observed by the user.

Description

technical field [0001] The invention relates to a method for handling capacity bottlenecks in digital networks, in particular digital home networks, where at least two devices or applications with a common interface for influencing internal resource allocation in the system access a data transmission medium with a non-constant bandwidth H. Background technique [0002] Process information by addressing the digitization and linking of media growth. In the context of the home, the associated network is the Digital Home Network (IHDN: Intra Home Digital Network). Televisions, radios, monitors, speakers, cameras, printers, scanners, computers, telephone devices, voice recognition systems, home device controls, security devices, etc. can be integrated in such an IHDN. Especially in audiovisual media with high data transfer rates up to 100 mbit / s, usage conflicts often arise when different applications compete for resources (device and network resources). [0003] This effect i...
