Abstract: A method for performing a performance measurement in a communication network. Each measurement point in the network identifies packets of a multipoint packet flow and selects therefrom a number of samples, based on the value of a sampling signature calculated by applying a hash function to a bit mask in each identified packet. For each sample, a performance parameter and the packet's content are provided to a management server. The management server identifies a cluster of measurement points such that each identified packet of the multipoint packet flow received by a cluster's input measurement point is also received at a cluster's output measurement point. Amongst the performance parameters provided by the cluster's measurement points, the performance parameters relating to samples belonging to a certain packet sub-flow are identified, based on the packet's content. Then, a performance measurement is performed on the packet sub-flow.

Abstract: In method of protecting signaling messages in a hop-by-hop network communication link between a source node and a destination node, a source node public digital signature verification key and a respective source node private digital signature key associated with said public digital signature verification key are provided to the source node. The source node public digital signature verification key associated with the source node private digital signature key is also provided to the destination node. The source node builds a message including a sequence of Information Elements, and calculates, for each Information Element, an Information Element hash value. The source node also calculates a sequence hash value of a concatenation of the calculated Information Element hash values, and generates a source node digital signature by digitally signing the calculated sequence hash value. An intermediate node receives and forwards the signaling message to the destination node.

Abstract: An apparatus and associated method for processing packets transmitted in a packet-switched communication network includes a sampling module that identifies amongst the received packets a plurality of samples distributed in a statistically uniform way amongst at least two non-overlapping sample sequences. Each sample sequence is then subjected to at least one identification rule, thereby identifying in the sample sequence at least one sub-sequence of samples fulfilling the at least one identification rule. The identification rule comprises a condition on the value of at least one identification field of the packets. Then, at least one parameter indicative of a behavior of the at least one sub-sequence of samples is provided.

Abstract: An electric energy supply management method includes having a certifier system define a reference electric power profile for an electric apparatus, and having the certifier system provide a device coupled to the electric apparats and to a socket that delivers electric energy provided by an electric energy supplier. The device is associated only to the electric apparatus through the reference electric power profile. The method also includes having a user of the electric apparatus couple the electric apparatus to the socket through the device, and having the device check that the electric apparatus is coupled to the socket by comparing a measured electric power profile of the electric apparatus to the reference electric power profile. If the check has a positive outcome, the method has the device collect measurements about the electric power used by the electric apparatus and certify them as energy consumptions of the electric apparatus.

Abstract: A telecommunication system monitors, for a plurality of services, a number of service requests from users and quality of service perceived by the users while using the services. A self-organizing network module determines a correlation between at least one configuration parameter, the number of service requests and the quality of service perceived, and, based on the correlation, a target number of service requests, and a target quality of service, determines an updated value for the at least one configuration parameter. Then the self-organizing network module commands the telecommunication system to implement reconfiguration thereof based on the updated value of the at least one configuration parameter.

Abstract: A method for enabling a round-trip packet loss measurement in a packet-switched communication network wherein a first node and a second node exchange packets comprising a packet loss field settable to an idle value or one or more measurement values. The first node performs a generation step whereby first packets having their set to a measurement value are transmitted to the second node. For each received first packet, the second node transmits back a second packet having its set to a measurement value. The first node then performs a reflection step whereby, for each received second packet, it transmits to the second node a respective third packet having its set to a measurement value. The time lapsing between start of the generation step and start of the reflection step has a predefined and substantially constant duration.

Abstract: A method for a wireless network, including a node and a first device covered by the node, the node acting as serving node for the first device, and the first device transmitting first data to the node over a first link, includes determining presence of a second device covered by the node, the second device transmitting second data to a serving node over a second link, determining radio quality of the first link, determining radio quality of the second link, and determining radio quality of a third link between the second device and the first device. If the radio quality of the third link is higher than the radio quality of the second link, the second device transmits the second data to the first device over the third link and the first device retransmits, over the first link, the second data to the node.

Abstract: A method is provided for transmitting encrypted packets from a first node to a second node of a communication network. The first node pads each plaintext packet with a respective padding content. The padded plaintext packets are then encrypted and transmitted to the second node. For each plaintext packet, the first node randomly selects the padding size in a range comprised between a minimum padding size and a maximum padding size. If the size of a plaintext packet is lower than a predefined minimum packet size, the minimum padding size is set equal to the difference between predefined minimum packet size and the plaintext packet size.
