SDN Controller receives the REST based requests at its northbound and abstracts the underlying network infrastructure from individual devices- Allowing expansion of vendor agnostic, open source network elements at the Transport network.

  • Setup Low level solution design
  • Preparing hardware resources for Microwave, Routers and Optic Transport
  • Network planning and network setup SDN controller and SDN Mediators and transport network elements
  • Test automation ? zero touch provisioning
  • Enhancement of UML to YANG tool, for the automated generation of YANG models for standardization of YANG interfaces ? MW, Routers and Optic devices

Analyst
In carrier aggregation, multiple carriers are aggregated to provide high bandwidth to the customers, provided that the user equipment is capable of multicarrier transmission and reception. It was required to analyse those changes brought into the network are reflected transparently into the operational tools and no misleading data or information exists in the operational tools that could result into wrong Alarming or wrong inventory data.

  • Requirements gathering from tools lifecycle managers, problem definition and Data analysis of the affected Systems.
  • Determining the adaptation effort in the various OSS Tools / components. (For example, Inventory, Fault Management, Performance Management, Reporting, ticketing systems).
  • Preparation of an implementation recommendation, adapting of concerned OSSTools / components, from the viewpoint of the lowest possible System interference.
