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: System and method embodiments are provided for configuring a network to forward traffic from a first network zone to a second network zone. In an embodiment, a first zone controller of the first zone receives information indicating network capability. The information includes a plurality of parameters of a constraint function. The first network controller provisions a network node, e.g., at the second zone, to forward traffic from the first zone to the second zone in accordance with the received information. The information indicating network capability includes one or more variables relating to the constraint. The constraint relates to at least one current traffic level or at least one wireless link in the second zone.
