Patent ID: 8068422

Claim:
An arrangement for controlling communication of data packets through one or more communication networks or network domains having an identifying means for identifying real-time or non-bursty data packet traffic and a separating means for separating real-time data packet traffic from bursty data packet traffic, the arrangement, being arranged in a node, comprising: autonomous, flow-based admission control means for controlling the admission of real-time data packets; a flow admittance capacity indicating means, wherein the autonomous, flow-based admission control means is in communication with the flow admittance capacity indicating means, adapted to keep information about the amount of real-time data packet flows that is admissible in the node; a flow information holding means adapted to hold information about the current number of admitted and/or non-admitted real-time data packet flows, the flow admittance capacity indicating being in communication with the flow information holding means; and the autonomous, flow-based admission control means adapted to detect whether an arriving packet belongs to a current admitted flow, and then to admit the packet, and being further adapted to, if the packet does not belong to a current admitted flow, verify with the flow admittance capacity indicating means if there is capacity left such that the new flow can be accepted, and if so, then to admit the packet, and in that it is adapted to, if there is no capacity left, reject the packet.
