Abstract: The control system includes a monitoring device operable to determine information related to resource availability associated with the network entity and to communicate the information related to the resource availability to a network controller. The control system includes a data relay device, which is operable to relay data packets between a plurality of network nodes. The data relay device is operable to receive information related to data packet relaying to the network entity from the network controller. The network controller apparatus includes one or more communication interfaces, which are operable to receive information related to a resource availability from a monitoring device. The one or more communication interfaces are operable to communicate information related to data packet relaying to a data relay device.

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: In one aspect, a communications network, wherein capacitor tunnels for particular services, for example for a quality of service are arranged on the link paths between the network nodes is provided. For preventing the capacity blocking or underused, the tunnel capacities are adapted according to a time-variable communication matrix. In a particular embodiment, a stock of transmission capacity common for a number of link paths is maintained, wherein a capacitor tunnel takes the data transmission capacity from the stock, when a top traffic threshold is exceeded or returns the data transmission capacity in the stock when the lower traffic threshold is under permissible level, respectively.
