Abstract: The invention concerns a method of providing resource admission control to packet flows (11, 12, 50) associated with sessions in a communication network (2), and an access controller (21, 22) to execute this method. The communication network (2) handles packets according to priority levels assigned to the packets. The priority levels comprise at least a first and a second priority level wherein the first priority level is higher than the second priority level. First, a packet flow (12) associated with the new session is identified when packets of the packet flow (12) enter the communication network (2). Preferably, the new session is a real-time session. The second priority level is assigned to the identified packet flow and the packet flow (12) is handled according to the second priority level within the communication network (2). A congestion level is measured in the communication network (2).

Abstract: Method to provide video chunks to a client entity (C) using a request-response protocol. Each video chunk is available at a server entity (S) as a plurality of encoded video chunks encoded according to respective quality levels.

Abstract: The invention relates to a device for the retrofitting of a computer with commercial plug-in units (1), wherein the computer is provided with plug-in slots whose format does not correspond to that of the commercial plug-in units (1). A retrofitting device of this kind is characterized in that a plug-in unit carrier (2) is provided with an open-edged recess for the accommodation of the commercial plug-in unit (1), where the plug-in unit carrier (2) comprises interface means (3 and 5) for adapting the inputs and outputs of the plug-in unit (1) to the inputs and outputs of the plug-in slot and the plug-in unit/carrier assembly substantially corresponds to the format of the plug-in slot.
