Abstract: System and method embodiments are provided for enabling software defined topology (SDT) to interwork with network function virtualization (NFV) and software defined networking (SDN). In an embodiment, a method for software defined topology (SDT) management interworking with network function virtualization (NFV) and software defined networking (SDN) includes receiving, at an SDT Manager, from a service customer, a service request comprising a virtual service function forwarding graph (VSF FG); selecting a virtual network function (VNF) forwarding graph (FG) template in accordance with the received service request; generating a virtual function (VF) FG in accordance with the service request and the selected VNF FG template; selecting a point of presence (PoPs) for a VF in the VF FG; and transmitting, to an NFV Manager, instructions to instantiate the VF in accordance with at least one of the generated VF FG and the determined PoP.

Abstract: A method and system for machine type communication (MTC) service management using network function virtualization (NFV) is disclosed. In an embodiment, a method for a machine type communication (MTC) service management using a virtual network function (VNF) includes receiving, by a virtual serving gateway (v-s-SGW), a request for an MTC service from a MTC device through a radio node associated with the MTC device; sending, by the v-s-SGW, an authentication request to an MTC server to authenticate the MTC device; receiving, by the v-s-SGW, an authentication response from the MTC server; and establishing, by the v-s-SGW, an MTC bearer between the v-s-SGW and the radio node if the authentication is successful; wherein the v-s-SGW comprises a virtual connection management (v-CM) and a serving gateway (s-SGW).

Abstract: A method for network adaptation includes receiving, by an adaptation coordinator of a virtual network, a performance measurement generated at a performance checkpoint located in the virtual network. The method also includes generating, by the adaptation coordinator, a first update of a service-specific configuration of the virtual network. The first update includes at least one of a modification of a performance checkpoint configuration, a modification of a Virtual Network Function (VNF) configuration, a modification of a protocol configuration, a modification of a resource allocation input, or a modification of a logical graph. The service-specific configuration includes a configuration of a plurality of logical nodes and a plurality of logical links of the virtual network in accordance with a service-specific data plane logical topology.
