摘要： Embodiments provide systems and methods for managing resources in networks which utilize network slicing. Embodiments include systems and methods for monitoring performance in networks which utilize network slicing when the resources of a network domain are allocated to more than one slice. Embodiments include systems and methods for monitoring performance when resources of a slice are controlled by different network operators/service providers. A domain manager can make the performance measurement data available per network allotment instance with an identifier indicating to which virtual network service the performance measurement data belongs.

摘要： A method of providing a network slice service includes a mobile network operator (MNO): providing one or more service profiles to a virtual service provider (VSP) serving a user population including a plurality of user devices, each service profile comprising attributes defining characteristics of a respective network slice service offered by the MNO, the network slice service comprising any one or more of: a Virtual Network with E2E service requirements; a Virtual Network with a specified network topology; and a virtualized infrastructure. The MNO receives a request for a selected network slice service from the VSP; determines whether or not the requested service can be provided; and responsive to determining that the requested service can be provided: sending a Service Level Agreement (SLA) for the network slice service to the VSP; and subsequently facilitating a network slice service instance in accordance with the SLA.

摘要： A method includes iteratively executing, by a computer, a scheduling process computing an allocation of wireless access network data rate to each link between an Access point and a User Equipment within a coverage area of the Access Point, and a routing process computing an allocation of wired network resources to each wired link between the Access Point and nodes of a wired network. The scheduling and routing processes are independent of each other. At each iteration, information of the allocated wireless access network data rate is passed to the routing process; and information of the aggregate allocated data rate for each service at the Access Point is passed to the scheduling process.

摘要： Methods and apparatus for determining whether to admit a virtual network using a set of communication network resources are provided. Different network resources can be owned by different infrastructure providers. Virtual network requests include a spatial profile of traffic requirements to be accommodated, and a determination is made as to whether the request can be accommodated based on available network resources. The resources include available backhaul link capacities. The resources can include computing resources for supporting service functions of the virtual network. Monitored network resource usage and traffic corresponding to the virtual network can be used to adjust future requests and accommodations. When a virtual network cannot be accommodated, a counter-offer can be made. Accommodation may incorporate monetary considerations. A feasibility computation of the admission procedure is formulated.

摘要： A method and apparatus supporting service function chaining in a communication network is provided. Service function chaining requires packets of a service to pass through a defined sequence of service nodes of the network. Traffic engineering support includes defining service segments, determining demands for each service segment, determining flow group conservation constraints using the determined demands, and determining a resource allocation for data links which respects the flow group conservation constraints along with a link capacity constraint. A service-based forwarding operation re-labels packets as they traverse each service segment, and forwards packets toward a destination service node of each service segment.

摘要： Methods for configuring user plane functions associated with a network slice. The methods include: creating a user plane configuration profile specific to at least one of an access technology and a user plane function; associating the user plane configuration profile with a network slice instance; selecting the network slice in response to a service request; and communicating the user plane configuration profile associated with the selected network slice instance to a control plane function.
