Description As a long-term target of SDN activities at the Transport Network and to provide the
value added service on future 5G network infrastructure.

SDN based infrastructure to manage the Microwave, Optic Transponders and
Routers of the Live Transport Networks is seen as a long-term solution.

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.


Role Integration Engineer

Tasks - 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

Description STOV is the Radio Network planning used by Vodafone German to plan new Radio
site, to enhance or edit existing Radio network sites.

Existing version of STOV is based on the Sybase based database which is 20 years
old. The existing solution is based on 8 database instances and each instance
contains the data of that particular region.

STOVAtoll Centralization is going to introduce a centralized database for all user
where each user can plan across the regions and make changes according to
allocated access rights.

Apart from that the Concept of Single Sing On is also introduced where the users
are assigned rights to their Windows user and with a single login the users can
navigate between STOV and Atoll

the customers, provided that the user equipment is capable of multicarrier
transmission and reception. It was required to analyse that 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.
