Juniper Networks debuted its cloud-enabled branch (CEB) Software-Defined Wide Area Network (SD-WAN) capabilities in 2016. Juniper CEB offers SD-WAN functionality that securely manages connections across branch locations, which can deploy applications and services from the cloud via an open platform for third-party services. Juniper CEB provides a consistent user experience across all branch locations and allows the locations to take advantage of cloud-hosted applications.
According to Juniper, CEB simplifies the deployment and automation of branch office networking. It contains SD-WAN functionality and cloud-based security components that monitor security threats across branches. Branches can use various types of network links according to their needs; for example, to reduce costs, branches can move lower-priority traffic from MPLS to broadband or LTE.
Juniper SD-WAN Features
Juniper CEB includes the company’s Contrail Service Orchestration, which supports both Juniper and third-party services. For SD-WAN capabilities, Juniper combines the Contrail Service Orchestrator with its NFX Network Services Platform, which provides routing and switching functionality. The NFX simply plugs in on-premises, and it auto-homes to communicate with Contrail Service Orchestration.
Contrail Service Orchestration is essentially a suite of products for designing and deploying network services. Juniper SD-WAN provides a RESTful API to connect with service providers’ operational support systems (OSS) and business support systems (BSS) applications and is responsible for many management and network orchestration (MANO) activities.
Juniper SD-WAN’s Contrail Service Orchestration includes the following features:
- An administration command-line interface (CLI) for managing customers
- The Cloud CPE Tenant Site and Service Manager and the Identity and Access Manager for mapping each customer’s network services to the appropriate gateway resources
- The Customer Portal, which lets customers manage sites and services for their organizations
- The Network Service Designer for designing, creating, managing, and configuring network services through a GUI
- The Network Service Orchestrator for lifecycle management of network service instances
- The Service and Infrastructure Monitor for providing data about the Cloud CPE Centralized Deployment Model, 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); and software components running in Contrail Cloud Platform
- The VNF Manager for creating VNF instances and managing their lifecycles
Juniper SD-WAN Differentiation
Juniper SD-WAN touts is ease of operation and a focus on minimizing intervention while improving operational efficiency and reducing operational cost. The company also values on-demand customization, allowing policy-driven, software-controlled, on-demand service chain customization based on customers’ business policies.
