Abstract:
1. A method for measuring quality of service at an application level in a telecommunication network, the method comprising: monitoring operation of an application by a monitoring apparatus through a network interface including: storing network data including the filtered data packet in a buffer of the monitoring apparatus, transmitting said network data to at least one measuring and signaling apparatus for analysis of the network data at the at least one measuring and signaling apparatus; detecting a critical situation related to said quality of service, by the at least one measuring and signaling apparatus which is separate from the monitoring apparatus and the two network nodes; generating, in response to said critical situation, a trigger signal subsequent to said monitoring apparatus transmitting said network data, by the at least one measuring and signaling apparatus; receiving said trigger signal at a coordination apparatus separate from the monitoring apparatus and the at least one measuring and signaling apparatus; transmitting, by the coordination apparatus, said trigger signal to said monitoring apparatus; and in response to the generation of said trigger signal, collecting by an archive apparatus, said data packet stored in said buffer of said monitoring apparatus, wherein the data packet is indicative of a behavior of the telecommunication network.
