[Abstract] Over⁃the⁃top services and cloud services have created great challenges for telecom operators. To better meet the requirements of cloud services, we propose a decoupled network architecture. Software⁃defined networking/network function virtualization (SDN/NFV) will be vital in the construction of cloud⁃oriented broadband infrastructure, especially within data centers and for interconnection between data centers. We also propose introducing SDN/NFV in the broadband access network in order to realize a virtualized residential gateway (VRG). We discuss the deployment modes of VRG.
