The Juniper Networks Cloud CPE solution transforms traditional branch networks, offering opportunities for high flexibility of the network, rapid introduction of new services, automation of network administration, and cost savings. Based on the European Telecommunications Standards Institute (ETSI) standards for Network Functions Virtualization (NFV) management and orchestration (MANO), the Cloud CPE solution offers end-to-end provisioning of Layer 4 through Layer 7 network services through an open, cloud-based architecture. The solution supports both Juniper Networks and third-party virtualized network functions (VNFs) that network providers use to create the network services.

The solution can be implemented by service providers to provide network services for branch offices for their customers or by Enterprise IT departments in a campus and branch environment. In this documentation, service providers and Enterprise IT departments are called service providers, and the consumers of their services are called customers.

The solution offers 2 deployment models:

  • Cloud CPE Centralized Deployment Model (centralized deployment).

    In the centralized deployment, customers access network services in a service provider’s cloud.

  • Cloud CPE Distributed Deployment Model (distributed deployment).

    In the distributed deployment, customers access network services on an NFX Series Network Services Platform, specifically an NFX250 device, located at a customer’s site.

The Cloud CPE Solution uses the following components for the NFV environment:

  • For the centralized deployment:
    • Network Service Orchestrator provides ETSI-compliant management of the life cycle of network service instances.

      This application includes RESTful APIs that you can use to create and manage network service catalogs.

    • Contrail Cloud Platform provides the underlying software-defined networking (SDN), NFV infrastructure (NFVI), and the virtualized infrastructure manager (VIM).
  • For the distributed deployment:
    • Network Service Orchestrator, together with Network Service Controller, provides ETSI-compliant management of the life cycle of network service instances.
    • Network Service Controller provides the VIM.
    • The NFX250 device provides the NFV infrastructure (NFVI).

The following Contrail Service Orchestration components connect to Network Service Orchestrator through its RESTful API:

  • Administration Portal, which you use to set up and manage your virtual network and customers through a graphical user interface (GUI).
  • Customer Portal, which is an application that you can provide to customers to enable them to manage sites and services for their organizations through a GUI.
  • Network Service Designer, which enables design, creation, management, and configuration of network services through a GUI. Network services are stored in the network service catalog.
  • Service and Infrastructure Monitor, which works with Icinga, an open source enterprise monitoring system to provide real-time data about the Cloud CPE solution, such as the status of virtualized network functions (VNFs), virtual machines (VMs), and physical servers; information about physical servers’ resources; components of a network service (VNFs and VMs hosting a VNF); counters and other information for VNFs.
