Access control for a packet-oriented network, taking into account resilience requirements

摘要

The invention relates to a method for providing resources for adapting the routing process in response to the failure of a network element in a packet-oriented network. Barring checks that use thresholds are provided to control the volume of traffic in the network. Data packets are barred if their routing would otherwise mean the crossing of a threshold. According to the invention, the thresholds are defined by taking into account failure topologies or possible malfunction scenarios, to ensure that a corresponding malfunction does not lead to an overload in the network. Said definition of the thresholds allows resources to be provided or reserved to all intents and purposes for intercepting malfunctions. The advantage of the invention is that quality criteria can be upheld and quality of service features guaranteed, even during the malfunctions.
