Introduction

The Juniper Networks Cloud customer premises equipment (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 the following deployment models:

  • Cloud CPE Centralized Deployment Model (centralized deployment)

    In the centralized deployment, customers access network services in a service provider’s cloud. Sites that access network services in this way are called cloud sites in this documentation.

  • Cloud CPE Distributed Deployment Model (distributed deployment)

    In the distributed deployment, customers access network services on a CPE device, located at a customer’s site. These sites are called on-premise sites in this documentation.

  • A combined centralized and distributed deployment

    In this combined deployment, the network contains both cloud sites and on-premise sites. One customer can have both types of sites; however, you cannot use the same network service package for cloud sites and on-premise sites. If you require the same network service for cloud sites and on-premise sites, you must create two identical network service packages with different names.

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

  • When end users access network services in the cloud:
    • 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).
  • When end users access network services on a local CPE device:
    • 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 CPE 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.

    You can deploy the Cloud CPE solution in a demonstration (demo) or production environment. Table 1 shows the number of sites and VNFs supported for each environment.
