Abstract: A method for performing a performance measurement on a multipoint packet flow transmitted in a packet-switched subnetwork. A monitoring network of measurement points is implemented in the subnetwork. All packets have a marking value, which is periodically switched between first and second marking values. Each measurement point receiving a marked packet updates a couple of performance parameters, one per each marking value. Since not all the measurement points receive the same packets of the multipoint packet flow, to provide a performance measurement a cluster of measurement points is firstly identified in the monitoring network, which possesses the following property: each packet received at the input of the cluster is also received at the output of the cluster, if no packet loss occurs. The performance parameters provided by input and output measurement points of the identified cluster are then used for providing the performance measurements.

Abstract: In a method for processing messages exchanged on a social network, a data processing apparatus gathers from the social network a reference set of messages pertaining to a user-selected reference context. The data processing apparatus then applies a multidimensional aggregation to the reference set of messages, whereby the messages of the reference set are grouped in an multidimensional array of groups having at least two dimensions. In each dimension, the array comprises a number of groups that correspond to a number of values of a certain message feature. Each group in a dimension corresponding to a certain message feature aggregates all the messages of the reference set whose message feature has a same value. Then, a user interface is displayed, which shows the reference set of messages as aggregated in at least two dimensions of the array.

Abstract: A method for managing a wireless network includes collecting a sequence of traffic data samples and arranging the sequence of data samples in a level-0 residual matrix having a dimension corresponding to a time scale defining a time window. The method also includes performing a least one cycle of subdividing the matrix based on the time scale to form traffic sample sets, calculating a functional that fits each sample set, and calculating an approximation of each sample set.

The method further forecasts a traffic data trend for another time window by generating predicted samples based on the previous calculations, and allocating resources of the wireless network based on the traffic data trend.

Abstract: A method for performance measurement in packet switched communication networks includes generating a flow of artificial packets having predefined packets lengths, which is then aggregated to the packet flow to be measured by an aggregator. The artificial packets are configured to follow the packet flow to be measured, starting from the point where aggregation is performed. Two measurement points are then provided after the aggregator, which identify the artificial packets based on their packet lengths and provide respective raw performance measurements indicative of the actual positions of the artificial packets in the aggregated packet flow. The raw performance measurements are then used for providing the performance measurements. Since the artificial packets are identified based on their packet lengths, no inspection of the packets' content is needed for identification purposes. The artificial packets may therefore be identified even if their content is uninspectable.

Abstract: It is disclosed a method for performing a performance measurement on a packet flow transmitted along a path through a packet switched communication network. Two or more measurement points are implemented on the path. Each measurement point calculates a sampling signature for each received packet by applying a hash function to a mask of bits of the packet. Then, it selects a number of measurement samples amongst the received packets, the measurement samples being selected as those packets whose sampling signatures comprise a portion of length S equal to a predefined sampling value. While performing the selection, the measurement point counts the number of selected measurement samples and retroactively adjusts the length based on this number. Then, the measurement point provides measurement parameters relating to the selected measurement samples.
