Forwarding quality control method in data network, involves adjusting existing provisioning level for each selected interface after detecting quality violations of at least one path

摘要

Quality violations are detected by combining knowledge about different end-to-end measurements performed in network and knowledge about network topology. Existing provisioning level for each selected interface is adjusted and the level defines maximum admitted sum of forwarding resources requested directly or indirectly by applications, such that the usage of each path detected to have limited forwarding quality violations. Independent claims are also included for the following: (1) node; and (2) computer program product for controlling forwarding quality in data network.
