Abstract: A controller is provided for a Cloud based service handling multiple types of traffic in a telecommunications network, the controller comprising: a first stage configured to automatically model use of Cloud resources allocated to the service for specific workloads of each of a plurality of traffic types, so as provide a variety of models for each traffic type; a second stage configured to automatically reduce the number of and generalise the models so as to provide generalised models for each traffic type applicable to other workloads than the specific loadings; a third stage configured to automatically evaluate accuracy of the generalised models for various combinations of given workloads, in each combination each of the given workloads being of a corresponding traffic type, and to select one of the generalised models dependent upon evaluated accuracy; and a fourth stage configured to control operation of the Cloud resources according to the selected model.

Abstract: A capability for providing policy enforcement in a topology abstraction system is presented. The capability for providing policy enforcement in a topology abstraction system may support use of topology abstraction policies to control abstraction of topology information of a topology (e.g., a network topology of a communication network or any other suitable type of topology). The capability for providing policy enforcement in a topology abstraction system providing an abstract representation of a topology may support use of topology abstraction policies to control selection (or acceptance) of topology elements for inclusion within the abstract representation of a topology and filtering (or rejection) of topology elements from being included within the abstract representation of a topology.

Abstract: Various exemplary embodiments relate to a method of determining a cost for a routing path in a network. The method includes: receiving a first metric for a plurality of links in a network, the first metric being a routing metric used to determine routing in the network; determining a routing path including a subset of the links based on the first metric, the routing path having an initial cost based on the first metric; receiving second metric information including a second metric that is different from the first metric; and calculating a corrected cost for the routing path based on the second metric.

Abstract: Various exemplary embodiments relate to a method for scaling out a cloud application, the method including: receiving a virtual private network (VPN) scale out request at a network management system (NMS), the scale out request including communication requirements from a cloud computing manager; determining the value of communication parameters corresponding to the communication requirements for a set of potential VPN endpoints; determining that only a portion of the set of potential VPN endpoints meet the communication requirements based upon the communication parameters; and sending an indication to the cloud manager that only a portion of the set of potential VPN endpoints meet the communication requirements.

Abstract: The invention concerns a method of providing a real-time communication connection over an IP communication network between a first entity and a second entity, as well as a sending and a receiving device to execute the method. The basic idea of the invention is to fragment non-real-time streams associated with the real-time communication connection at the first entity, to multiplex the fragments of the non-real-time streams into real-time streams of the real-time communication connection at the first entity, and to transmit the multiplexed real-time streams comprising the real-time streams and the fragments of the non-real-time streams via the real-time communication connection from the first entity to the second entity. In order to ensure a reliable quality of service of the real-time data, the real-time part of the multiplexed data stream is assigned the highest priority for transmission.

Abstract: A method of forwarding signaling information within a communication network is described. The signaling information is based on a signaling protocol (e.g SIP). A message is generated by encapsulating the signaling information (e.g. I?) according to given definitions (e.g. D). Furthermore, non-signaling information (e.g. R) is added to the message.
