    • 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.
    • 提供了系统和方法实施例,用于使得软件定义拓扑(SDT)能够与网络功能虚拟化(NFV)和软件定义网络(SDN)相互配合。 在一个实施例中,一种与网络功能虚拟化(NFV)和软件定义网络(SDN)交互工作的软件定义拓扑(SDT)管理的方法包括在SDT管理器处从服务客户接收包括虚拟服务功能的服务请求 转发图(VSF FG); 根据接收到的服务请求选择虚拟网络功能(VNF)转发图(FG)模板; 根据服务请求和选择的VNF FG模板生成虚拟功能(VF)FG; 在VF FG中选择VF的存在点(PoP); 以及根据生成的VF FG和所确定的PoP中的至少一个,向NFV管理器发送用于实例化VF的指令。

    • System and method embodiments are provided for traffic engineering (TE) in software defined networking (SDN). The embodiments enable a complete end-to-end TE solution between a user equipment (UE) and a source/destination across a radio access network (RAN). In an embodiment, a method in a network component for TE in a SDN includes receiving TE information from a first core network component in a core network, a RAN component, wherein the RAN is communicably coupled to the core network, wherein the TE information includes a TE objective; and determining a TE decision between at least one UE and a second core network component in the core network according to the TE information and the TE objective, wherein the TE decision comprises information for at least one end-to-end path solution between the at least one UE and the second core network wherein the path traverses the core network and the RAN.
    • 为软件定义组网(SDN)中的流量工程(TE)提供了系统和方法实施例。 这些实施例能够在用户设备(UE)和跨越无线接入网络(RAN)的源/目的地之间实现完整的端到端TE解决方案。 在一个实施例中,SDN中的TE的网络组件中的方法包括从核心网络中的第一核心网络组件接收TE信息,RAN组件,其中RAN可通信地耦合到核心网络,其中TE信息包括 TE目标; 以及根据所述TE信息和所述TE目标,确定所述核心网络中的至少一个UE与所述第二核心网络组件之间的TE决定,其中,所述TE决定包括用于所述TE信息和所述TE目标之间的至少一个端到端路径解的信息 至少一个UE和第二核心网络,其中路径穿过核心网络和RAN。
