Publication number: 20100125661Abstract: A method, apparatus, system, and computer program for analyzing properties of an application-specific end-to-end communication connection are presented. In a connection performance analysis apparatus, measurement data messages are received from a plurality of traffic-monitoring nodes arranged at selected intermediate points in a plurality of network segments of the application-specific end-to-end communication connection and from at least one end node of the end-to-end communication connection, wherein a measurement data message comprises information related to a travel time of at least one data packet of the end-to-end communication connection to the traffic-monitoring node or to the end node transmitting the respective measurement data message. Then, the connection performance analysis apparatus analyzes the received measurement data messages in order to determine a bottleneck of the end-to-end communication connection.Type: ApplicationFiled: November 20, 2008Publication date: May 20, 2010Applicant: VALTION TEKNILLINEN TUTKIMUSKESKUInventors: Pekka PERALA, Mikko HANSKI, Marko JURVANSUU, Jarmo PROKKOLA, Jouko SANKALA, Markus AHOKANGAS

Publication number: 20080037435Abstract: The invention relates to a method, measurement arrangement, analyser and analyser program for debugging transmission failures in a telecommunication network. In the method, the analyser utilizes both internal events of a telecommunication component and signalling messages transmitted in the telecommunication network. Internal events and external signalling messages are combined or correlated for speeding de-bugging.Type: ApplicationFiled: August 10, 2006Publication date: February 14, 2008Applicant: NETHAWK OYJInventor: Jouko Sankala
