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: The invention relates to a routing device for an access network, a routing module therefor and a routing method for an access network. The routing device comprises forwarding means able to determine a destination device for a message sent by a sending device. The message contains an anycast address being assigned to a first possible destination device and at least one second possible destination device of a group of destination devices. The forwarding means are able to determine the first destination device or the at least one second possible destination device out of the group of destination devices by assignment data. The assignment data comprise a link between the sending device and the destination device. The assignment data comprise credential data and/or are determined by means of credential data of a user of the sending device.
