Abstract: The invention concerns a telecommunication system (10) and a computer-implemented method for transferring media data from a first RTC client (30) over a QoS-sensitive network (N1) using the real-time protocol (RTP) to a second RTC client (40), wherein the quality of service is based on different traffic classes and the media data contain a first media type with a first traffic class (QoS1) and a second media type with a second traffic class (QoS2), comprising the following steps: media data, which contain a first media type with a first traffic class (QoS1) and a second media type with a second traffic class (QoS2), are bundled by the first RTC client (30) into second packets (P2), in each second packet (P2), the traffic class (QoS1, QoS2) for each media type is marked in layer 4 and/or layer 5 of the real-time protocol (RTP), the second packets (P2) are transmitted in the direction of the second RTC client (40), either before or during the transfer to the network (N1), the second packets (P2) are unbundled using the markings in layer 4 and/or layer 5 of the real-time protocol (RTP) and then bundled into first packets (P1), each of which has only one of the traffic classes (QoS1, QoS2), and the first packets (P1) are transmitted over the network (N1) to the second RTC client (40).

Abstract: A telecommunication system and a method for transferring media data from a first client over a QoS-sensitive network to a second client. The system and method can permit media data, which contain a first media type with a first traffic class and a second media type with a second traffic class to be bundled by the first client into second packets. In each second packet, the traffic class for each media type is marked in layer 4 and/or layer 5. The second packets can be transmitted toward the second client. Either before or during the transfer to the network, the second packets can be unbundled using the markings in layer 4 and/or layer 5 and then bundled into first packets, each of which has only one of the traffic classes. At least some of the first packets can then be transmitted over the network to the second client.

Abstract: A telecommunication system and a method for generating a real time connection between a first endpoint and a second endpoint in an IP network using an ICE STUN connectivity check follow a procedure that includes the steps of generating a list of possible connection paths between the first endpoint and the second endpoint, establishing a respective priority for each possible connection path included in the list, and generating the real time connection between the first endpoint and the second endpoint. During this procedure first there is an attempt to generate the real time connection using the highest-priority connection path. If this is not possible, then the system attempts to establish the real connection using the connection path with the next highest priority, until the real time connection is actually established. Furthermore, for each possible connection path, its respective quality-of-service value is determined and is considered when establishing its priority on the list.
