The Juniper Networks NFX250 Network Services Platform is a secure, automated, software-driven customer premises equipment (CPE) platform that delivers virtualized network and security services on demand. The NFX250 is part of the Juniper Cloud CPE solution, which leverages Network Functions Virtualization (NFV). It enables service providers to deploy and chain multiple, secure, and high-performance virtualized network functions (VNFs) on a single device.
Key components of the NextGen software include:
Linux - The host OS, which functions as the hypervisor.
VNF - A VNF is a virtualized implementation of a network device and its functions.
JCP - Junos virtual machine (VM) running on the host OS, Linux. The JCP functions as the single point of management for all the components.
JDM - An application container that manages VNFs and provides infrastructure services. The JDM functions in the background. Users cannot access the JDM directly.
L2 data plane - Manages Layer 2 traffic. The Layer 2 data plane forwards the LAN traffic to the Open vSwitch (OVS) bridge, which acts as the NFV backplane. The Layer 2 data plane is mapped to the virtual FPC0 on the JCP.
L3 data plane - Provides data path functions for the Layer 3 to Layer 7 services. The Layer 3 data plane is mapped to the virtual FPC1 on the JCP.
Open vSwitch (OVS) bridge - The OVS bridge is a VLAN-aware system bridge that acts as the NFV backplane to which the VNFs, FPC1, and FPC0 connect. Additionally, you can create custom OVS bridges to isolate connectivity between different VNFs.
This article provides references to information that would be useful for administration, configuration and troubleshooting of NFX-250 devices running the NextGen Software. Note:
This article applies only to NFX-250 running the NFX-3 software ie., the Next-Gen version. If you are unsure of the software version currently running on your NFX-250 (Next-Gen or non Next-Gen), refer to KB37304 -[NFX] How to identify if my NFX-250 is running NextGen (NG) or Non-NextGen Software [juniper.net] .
