20090202057 | Method For Identifying Undesired Telephone Calls - A method for identifying undesired telephone calls (Spit/Spam over IP), preferably in a VoIP network, in which the telephone calls coming in for a telephone subscriber, the callee, from at least one calling telephone subscriber, the caller, are subjected to a test or more precisely to a statistical analysis. The method is developed in such a manner that in the framework of the test for incoming calls, the time of the receipt of each call is determined and in each case the probability that the call is undesired is determined, where for the calculation of the probability the time of the receipt of the call, or a parameter dependent thereon, is related to the temporal distribution of previous undesired calls. | 08-13-2009 |

20110154016 | METHOD FOR AGGREGATING INFORMATION VALUES IN A NETWORK - A method for aggregating information values in a network, the network including trusted network nodes and untrusted network nodes, wherein a communication session is established by directing messages through the network along a network path from an originating network node ( | 06-23-2011 |
20110314146 | DISTRIBUTION MONITORING SYSTEM, DISTRIBUTION MONITORING METHOD, AND PROGRAM - A network distribution monitoring method is executed by a computer which configures each of a plurality of nodes, in a network which comprises the plurality of nodes which are connected with a management network. The network distribution monitoring method includes: generating a first detection message by detecting a first traffic on an object network of a corresponding one of a plurality of first predetermined applications, in each of first probe nodes of the plurality of nodes; transmitting the first detection message to a node determined from a first hash value to only a first function identifier showing a kind of the corresponding one or the first function identifier and address data of the first traffic; generating a first mediation processing result by performing first mediation processing on the first detection message to the plurality of first applications, in a first mediation node of the plurality of nodes; and storing a result of the first mediation processing in a first collector node of the plurality of nodes. In this way, the distribution monitoring system is provided in which it is possible to monitor the advanced function. | 12-22-2011 |
20120198062 | METHOD FOR MONITORING TRAFFIC IN A NETWORK AND A NETWORK - For providing a simple monitoring mechanism with reduced resource and performance requirements a method for monitoring traffic in a network is claimed, wherein a monitoring activity of at least two monitoring probes of the network is coordinated by a coordinating element, wherein at least two nodes of the network are able to operate as coordinating elements and wherein the responsibility for coordinating the monitoring activity of the monitoring probes is split between the nodes according to a compressed representation of flow parameter keys. Further, an according network is described, preferably for carrying out the above mentioned method. | 08-02-2012 |
20120207046 | METHOD FOR MONITORING A NETWORK AND NETWORK INCLUDING A MONITORING FUNCTIONALITY - A method for monitoring a network, wherein the network has a connected graph topology, in particular a tree structure, including a plurality of monitoring nodes that collect network measurement data, a plurality of mediator nodes each performing at least the task of aggregating network measurement data received from different monitoring nodes and/or other mediator nodes, and at least one root entity that receives network measurement data and/or aggregated network measurement data from the mediator nodes, is characterized in that the aggregation of network measurement data is performed by condensing network measurement data into a summarized probabilistic data structure. Furthermore, a network including a monitoring functionality is disclosed. | 08-16-2012 |
