Türk Telekom launched a comprehensive network transformation initiative to modernize its access infrastructure while addressing new features which cannot be applied to traditional vendor-specific architectures. Central to this effort is SEBA-VOLTHA – the open source, cloud-native broadband access management hosted by Linux Foundation Broadband (LF Broadband) – implemented under the SEBA (SDN-Enabled Broadband Access) framework. By deploying SEBA-VOLTHA across its access network, Türk Telekom achieved vendor neutrality, significant cost reductions, and enhanced service agility through a microservice-based architecture.
This case study presents Türk Telekom’s strategic approach, developed in collaboration with Netsia, highlighting the implementation aspects, the solutions created, and the significant results achieved. It demonstrates how Türk Telekom became the first operator in Türkiye to lead a large-scale, open source-based access transformation.
