Embodiment Construction

[0025]1 is a block diagram illustrating an example of a communication network for digital media distribution such as eg IPTV, video on demand (VoD), radio and other types of media, comprising an access node 100 . The access node 100 is connected to a regional IP network 160 and to several customer premises networks 170,180. Regional IP network 160 may also be referred to as an Ethernet aggregation network. The customer premises network 170, 180 may typically be a home network to which multiple televisions and / or computers are connected. Each customer premise network 170, 180 includes customer premise equipment 110, 120CPE. The CPE is the device that interfaces with the access lines 171, 181 and may for example be an ADSL modem or a cable modem with router functionality or similar. To each CPE 110, 120 several terminals, such as set-top boxes STB 111, 112, 122 and personal computers 121 may be connected. Each STB 111, 112, 122 is connected to a television (not shown in Figur...

Abstract

The invention relates to a method for providing resource admission control (RAC) of digital media streams between a media server and terminals in a customer premises network. The method is characterized by the steps of receiving from a terminal, a resource request comprising a resource requirement pertaining to a unicast digital media stream request, determining if transmission resources are available for the requested unicast digital media stream based on the resource request, and if so, transmitting a resource availability message pertaining to the unicast digital media stream request to the media server in order for the media server to begin streaming the requested unicast media stream towards the terminal. The invention further relates to an access node, a terminal and a media server.

Description

technical field [0001] The present invention relates to a method for providing Resource Admission Control (RAC) of digital media streams in a communication network. The invention also relates to a terminal, an access node and a media server for providing resource admission control of digital media streams in a communication network. Background technique [0002] Multimedia streaming services like IPTV offer huge opportunities for service providers and network operators to deliver a truly personalized service experience to their customers; however, ensuring adequate quality of experience (QoE) for end users subscribing to the service is also crucial. Therefore, resource admission control (RAC) functionality is required to ensure that end users are authorized to receive certain requested media and that transmission resources (such as eg sufficient bandwidth) required to provide the end user with certain requested media are available. Thus, the RAC function will only allow an ...
