NFX250 Overview

The Juniper Networks NFX250 Network Services Platform is a secure, automated, software-driven customer premised equipment (CPE) platform that delivers virtualized network and security services on demand. An integral part of Juniper’s fully automated Cloud CPE solution suite for NFV, this high-performance virtualized services platform helps service providers improve overall operational efficiency and service agility while empowering enterprise customers with immediate access to custom-designed managed services. Simultaneously supporting multiple Juniper and third-party VNFs on a single device and providing built-in, dynamic, policy-based routing, the NFX250 addresses the needs of small to midsize businesses as well as large multinational or distributed enterprises with a single, highly scalable solution.

NFX250 Network Services Platform are Juniper Network’s secure, automated, software-driven customer premises equipment (CPE) devices that deliver virtualized network and security services on demand. Leveraging Network Functions Virtualization (NFV) and built on the Juniper Cloud CPE solution, NFX250 enables service providers to deploy and service chain multiple, secure, high-performance virtualized network functions (VNFs) as a single device. This automated, software-driven solution dynamically provisions new services on demand.

Benefits of NFX250 Network Services Platform

The NFX250 is an integrated branch router and switch with a multicore CPU that enables it to run multiple Virtual Network Functions (VNFS). The NFX250 Network Services Platform provides these benefits:

  • Simultaneously supports multiple Juniper and third-party VNFs on a single device, providing built-in, dynamic, and policy-based routing

  • Provides and open framework that supports industry standards, protocols, and seamless API integration

  • Supports a variety of flexible deployments. A distributed services deployment model ensures high availability, performance, and compliance

  • Incorporates many advanced security features. Secure Boot feature safeguards device credentials, automatically authenticates system integrity, verifies system configuration, and enhances overall platform security

  • Modular software architecture provides high performance and scalability for routing, switching, and security enhanced by carrier-class reliability

  • Automated configuration eliminates complex device setup and delivers a plug-and-play experience

  • High performance simplifies network topologies and operations

NFX250 Components

The NFX250 consists of the following key components:

  • Juniper Device Manager: The Juniper Device Manager (JDM) is a low-footprint Linux container that provides these functions:

    • Virtual Machine (VM) lifecycle management

    • Device management and isolation of host OS from user installations

    • NIC, single-root I/O virtualization (SR-IOV), and virtual input/output (VirtIO) interface provisioning

    • Support for the Network Service Orchestrator module to connect to Network Activator

    • Inventory and resource management

    • Internal network and image management

    • Service chaining—provides building blocks such as virtual interfaces and bridges for users to implement service chaining polices

    • Virtual console access to VNFs including vSRX and vjunos

  • Junos Control Plane: Junos Control Plane (JCP) is the Junos VM running on the hypervisor. You can use JCP to configure the network ports of the NFX250 device, and JCP runs by default as vjunos0 on NFX250. You can log on to JCP from JDM using the SSH service and the command-line interface (CLI) is the same as Junos.
