Access Solutions

To unlock the full potential of gigabit broadband, service providers need to build a scalable network which can launch new services on the fly. This can be achieved by building virtual networks wherein network resources can be re-configured on demand basis. Traditionally, this has required significant investment, and hence creating a massive roadblock for service providers. But today, with the maturity of cloud technologies, availability of open source codes and abstraction of hardware from software layer ensures this transition with minimal additional cost.

At STL, we offer pFTTx which can virtualize last mile network to enable flexible gigabit broadband. pFTTx is an SDN-NFV, micro-services oriented, cloud-based network solution that radically elevates the network service provider’s business model. It helps in building virtual networks with open interfaces by abstracting software from hardware layer.It drastically reduces time to market for new digital services, sets the ball rolling for edge computing by disaggregating broadband networks and re-architecting central offices. While deploying this into our production network, we have implemented the SEBA (Software enabled broadband access), an ONF complaint reference platform. This platform serves as a benchmark for the community, customers, and industry and is helping in adoption of programmable FTTx PODS.

  • pFTTx (SDN) Controller: This is a software-defined controller that defines the data forwarding path across the FTTx network. This is a true cloud-native application which is based on open standards and a true CUPS (Control and User Plane Separation) model.

  • Edge Orchestrator: This is the orchestration engine for the FTTx network that enables container orchestration, workflow management, and FCAPS (for FTTx end device management). This works seamlessly with software and hardware components to provide a unified carrier-grade service experience.

  • White box OLT: This is a white-labelled hardware component of OLT which is controlled by pFTTx Controller and managed by Edge Orchestrator. This is an integral part of STL pFTTx stack that works with a whole ecosystem of partners supporting open interfaces.

  • White Box ONU/ONT: This is a white-labelled hardware component of ONU/ONT which is controlled by pFTTx Controller and managed by Edge Orchestrator. This is an integral part of STL pFTTx stack that works with a whole ecosystem of partners supporting open OMCI.

  • Non-Proprietary Protocols: This facilitates software stack internal messaging and external protocol communication through open, standardized, API and interfaces. This helps integrating third-party hardware (ONT/OLT) and also the existing operator NMS and OSS as long as they support open, standardized API and interfaces.

  • vOLTHA: This is a software-defined hardware abstraction platform that acts as a mediation between the control plane and forwarding plane. Thisabstraction platform helps in integration of open white box hardware with the software-defined platform.
