A VNF is a consolidated offering that contains all the components required for supporting
a fully virtualized networking environment. A VNF has network optimization as its focus.
JDM enables:
•
Management of guest virtualized network functions (VNFs) during their life cycle.
•
Installation of third-party modules.
•
Formation of VNF service chains.
•
Management of guest VNF images (their binary files).
•
Control of the system inventory and resource usage.
Note that some implementations of the basic architecture include a Packet Forwarding
Engine as well as the usual Linux platform hardware ports. This allows better integration
of the Juniper Networks data plane with the bare-metal hardware of a generic platform.
The disaggregated Junos OS architecture enables JDM to handle virtualized network
functions such as a firewall or Network Address Translation (NAT) functions. The other
VNFs and containers integrated with JDM can be Juniper Networks products or third-party
products as native Linux applications. The basic architecture of the disaggregated Junos
OS is shown schematically in Figure 2 on page 4.
