    摘要： A method for providing a service in a telecommunications network comprising a plurality of resources and at least one slice of resources. The method comprises actions of receiving, creating and modifying. A request is received from a customer to serve a group of user devices by a first service. A new NSI is created to provide the first service, if it is determined that there is no existing NSI, shareable between a plurality of services, that can provide the first service. An existing NSI, shareable between a plurality of services, is modified to serve the group of user devices by that first service in addition to at least one second service that is already provided by the existing NSI, if it is determined that the existing NSI can provide the first service.

    摘要： A method and system for routing data in a content distribution network (network) from a plurality of content sources that store the same data to a receiving device, including generating a network topology in which each of the content sources that store the data are represented as virtual routers that are each connected to a common virtual content server by respective infinite capacity communication links; determining optimized routing through the network topology for the data from the virtual content server to the receiving device; and determining, in dependence on the optimized routing, a data allocation for each of the content sources to transmit data through the network to the receiving device.

    摘要： A method and apparatus for deploying a set of network caches in a communication network is provided. A set of network nodes is identified such that, for each of a set of client device locations, and for at least a number c of the set of nodes, output of a coverage cost function is no greater than a threshold. The coverage cost function receives as input a client location and one of the nodes. The set of network caches are then located at the respective set of nodes. The set of network nodes can be selected from plural candidate sets based on a utility criterion. The candidate sets can be generated by successive addition and/or removal of nodes. Information obtained from a Traffic Engineering function can be used to direct selection of the set of nodes. A cache-client association can be generated for directing clients to particular caches.

    摘要： Methods and systems for determining placement of a virtual serving gateway. The method includes obtaining a set of input information. The input information includes network information and configuration information providing one or more parameters for placing the virtual serving gateway, and includes at least one mobility insensitivity criterion. Placement of the virtual serving gateway at one or more physical hosts is determined in accordance with the network information and the configuration information. The virtual serving gateway is distributively placeable across physical hosts. A set of output information is generated. The output information includes information identifying placement of the virtual serving gateway at the physical hosts, and a hosting percentage for each physical host.

    摘要： Methods and systems for generating a virtual network topology for machine-to-machine communications. A set of input information including network information and configuration information is obtained. One or more virtual serving gateways for the virtual network are located at one or more physical hosts, and each machine is associated with a respective virtual serving gateway, in accordance with the network information and the configuration information. A set of output information defining the virtual network topology is generated.
