Virtual OLT Software Framework

A full featured IP/routing/MPLS software stack that provides further leverage to support different deployment models for PON access and aggregation.

Altran’s software framework offers a disaggregated solution for virtual OLTs (Optical Line Terminals).

The software framework uses a hardware abstraction layer to integrate on any COTS, whitebox, open or proprietary hardware platform depending upon the need.

Network operators are reinventing the access network to be more efficient, programmable and agile, so that they can evolve rapidly to meet subscriber demand. The Altran software architecture to disaggregate hardware and software components, around abstraction layers, to leverage the latest in economical and high-performing hardware, allows OEMs and NEPs to meet the new network demands, and thereby deliver to operators, the ability to design agile and programmable networks.

The hardware and vendor agnostic nature of the software framework, together with Altran’s partner ecosystem, helps OEMs and NEPs to optimize both software and hardware R & D budgets and cycles, thus greatly accelerating time to market without huge upfront capex outlays.

Virtual OLT Software Framework


This OLT software framework solution supports the following:

  • System and device management with Openflow/Netconf/SNMP/CLI
  • Subscriber management
  • Policy management
  • Bandwidth management
  • Fault management
  • Dynamic bandwidth allocation
  • Software management
  • Performance management
  • Standards support for various encapsulations for subscriber traffic over Ethernet/VLAN

In partnership with Edgecore, the framework is supported on Edgecore’s ASXvOLT16 white box OLT ( The framework can support other hardware platforms as well.
