Abstract
A method for managing a communications network includes providing a parent network manager in a parent domain of the communications network, and providing a child network manager in a child domain of the communications network. The parent network manager comprises at least one of a parent Service Oriented Network Auto Creation (SONAC) function and a parent MANagement and Orchestration (MANO) function. The child network manager comprises at least one of a child Service Oriented Network Auto Creation (SONAC) function and a child MANagement and Orchestration (MANO) function. The parent and child network managers cooperate to optimize management of the parent and child domains of the communications network.
Claims9
A method for managing a communications network, the method comprising:
- providing a parent network manager in a parent domain of the communications network, the parent network manager comprising at least one of a parent Service Oriented Network Auto Creation (SONAC) function and a parent MANagement and Orchestration (MANO) function;
- and
- providing a child network manager in a child domain of the communications network, the child network manager comprising at least one of a child Service Oriented Network Auto Creation (SONAC) function and a child MANagement and Orchestration (MANO) function;
- wherein at least one of the parent network manager and the child network manager comprises the Service Oriented Network Auto Creation (SONAC) function,
- the parent and child network managers cooperating to optimize management of the parent and child domains of the communications network.
A network management entity of a communications network, the network management entity comprising:
- a Service Oriented Network Auto Creation (SONAC) function including:
- a Software Defined Topology (SDT) controller configured to define a logical network topology;
- a Software Defined Protocol (SDP) controller configured to define a logical end-to-end protocol;
- and
- a Software Defined Resource Allocation (SDRA) controller configured to define an allocation of network resources for logical connection in the logical network topology;
- and
- a MANagement and Orchestration (MANO) function including a Network Function Virtualization Orchestrator (NFVO) configured to receive topology information from the Software Defined Topology (SDT) controller of the SONAC function.
A network management entity of a communications network, the network management entity comprising:
- a Service Oriented Network Auto Creation (SONAC) function including:
- a Software Defined Topology (SDT) controller configured to define a logical network topology;
- a Software Defined Protocol (SDP) controller configured to define a logical end-to-end protocol;
- and
- a Software Defined Resource Allocation (SDRA) controller configured to define an allocation of network resources for logical connection in the logical network topology;
- wherein the SONAC is configured to implement functionality of a Network Function Virtualization Orchestrator NFVO function of a conventional MANO.
