DPU Software

Inango offers software for Distribution Point Unit (DPU) applications.

The DPU connects to homes via an existing physical infra-structure (phone lines or coaxial cables) using technologies such as G.fast or G.hn to provide high-speed Internet access to home owners.

The DPU Software is a complete operational system, including support for QoS, user authentication, Ethernet OAM, provisioning and more. It is fully field-upgradeable. Furthermore, the DPU is fully SDN-aware, supporting OpenFlow communication with the SDN server and modules for publicizing information about network interfaces and

connectivity. It is based on a highly portable architecture and supports a variety of network processor, switch and FPGAbased platforms.

The main functional modules of the DPU are shown below. As with all Inango products, we are happy to offer extensions and customization through our professional services group.


RG Software

Residential Gateway

The Residential Gateway is the heart of the networked home. It is also the platform on which many of our in-home features run.

Inango offers a comprehensive software package for Residential Gateway applications.

Fully managed via many means (TR-069, SNMP, NetConf, web, command-line or others) and based on Inango’s enhanced OpenWRT package, our suite offers a broad range of functionality that includes networking, NAT/firewall, VoIP, authentication and much more as summarized below. This is far from an exhaustive features list – please contact us for full technical information.

The RG software is fully field-upgradeable (either as a whole image or as specific individual modules) either on command or through an automated upgrade server.



Persistent Management Agent

The Persistent Management Agent (PMA) is used to allow Network Management Systems to manage DPU systems that may not be on-line. This is particularly useful in systems where the DPU’s are line-powered and may not have power at any given point in time.

Inango’s PMA supports both G.fast and G.hn DPUs but is designed to extend easily for other technologies. It acts as an intelligent proxy device for each of the managed DPUs, storing commands until they can be executed, saving system configuration and more.

It supports NetConf management in both directions (from an “upstream” NMS and to the “downstream” DPU’s) and includes the ability to manage the CPE devices connected to each DPU.

Moreover, since it is based on OpenDaylight, it can easily be extended by adding SDN functionality for network virtualization (an optional add-on).

Inango’s PMA is the ideal combination of standard infra-structures and state-of-the-art functionality.
