Introduction

Juniper Networks Cloud customer premises equipment (CPE) Centralized Deployment Model offers end-to-end provisioning of Layer 4 through Layer 7 network services through an open, cloud-based architecture. The deployment uses:

You can either use the Cloud CPE Centralized Deployment Model as a turnkey implementation or connect to other operational support and business support systems (OSS/BSS) through a northbound Representational State Transfer (REST) API.

In the Cloud CPE Centralized Deployment Model, virtualized network functions (VNFs) are located in a central cloud in a point of presence (POP) or data center owned by either a service provider, such as a telecommunications company, or a large enterprise. Customers access the central cloud through a Layer 3 VPN to obtain network services. You can use the Cloud CPE Centralized Deployment Model for existing Layer 3 VPN customers without changing CPE or access networks. Alternatively, you can enable access through a Layer 3 network interface device (NID).

The Cloud CPE Centralized Deployment Model uses the Contrail Service Orchestration software, which consists of the following components:

  • Network Service Designer, which enables design, creation, management, and configuration of network services. Network services are stored in the network service catalog.
  • Network Service Orchestrator, which is responsible for 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.
  • Cloud CPE Tenant, Site and Service Manager and its auxiliary component, Identity and Access Manager, which manage Cloud CPE customers and map each customer’s network services to the appropriate gateway resources. These applications provide northbound RESTful APIs to which you can connect OSS/BSS systems.
  • VNF Manager, which creates VNF instances and manages their life cycles.
  • Administration Portal, which you use to manage customers, their networks, and allocation of network services.
  • Customer Portal, which you can provide to customers to enable them to view the topology of their networks and to manage sites and services in their networks.
  • Service and Infrastructure Monitor, which provides both a visual display and detailed information about physical servers, virtual machines (VMs), software components, network services, and VNFs.
