Abstract: A method and a system for rating entities of a group is provided. Rating values for one or more other entities are received. The received rating values include a time stamp. A matrix of combined rating values is built, and entropy values for each entity are determined. The entropy value is indicative of a rate an entity rates other entities with a same rating value. Goodness values are determined for each entity. Each of the goodness values is dependent from a respective fairness value for each entity and the respective entropy value of each entity. The goodness value are indicative of a quality metric. The fairness values for each entity is determined. The fairness value is dependent on the related goodness value, the fairness value being indicative of a difference of an entity rating in comparison to other ratings. The determination of the goodness and fairness values are repeated until convergence.

The input documents of the second functional layer can contain transport-related information while the input documents of the first functional layer can contain application-related information.

Abstract: The invention is related to a method for resilient multi-path connections between edge devices of a communication network. First are determined connection-specific traffic distribution functions for the multi-paths depending on a plausible failure pattern of active and inactive paths of the multi-path of this connection. Further is selected the traffic distribution function for a multi-path depending on the current failure pattern of active and an inactive paths of the multi-path of this connection and is distributed the traffic of the connection onto the path of the corresponding multi-path pursuant to the selected traffic distribution function. An essential advantage of the invention is a significant decrease of network capacity for resilient multi-path connections. Another advantage of the invention is the short reaction time in case of an outage of one or more paths of the multi-path connections.

Abstract: The invention relates to a method for determining limits for the access control of traffic that is to be transmitted via a communication network. The limits are fixed in such a way that no overload situation can occur in the network; the probability of rejection of traffic flows is, wherever possible, is independent from the point of entry into said network; and resources are used as efficiently as possible. On the basis of limits wherein no overload situation occurs, the limits for the traffic control are raised in such a way that the blocking probability for traffic transmitted between pairs of marginal modes is lowered at the same time. The lowereing of said blocking probability is maintained if an overload situation were to occur in the network.

Abstract: Routing is one of the key issues in networks for communication of data. Conventionally, the optimization of the routing for a particular network is achieved by improving/changing/expanding the routing protocol. In order to optimize the routing of data networks without varying existing routing protocols, the present invention provides a method and a system for optimizing the routing of data to be communicated in a network. In particular, the invention achieves a homogeneous distribution of data communication traffic in a network by a minimization of the maximum link utilization and/or a minimization of the average link utilization of data links between nodes of the network.
