Deutsche Telekom recently announced its Access 4.0 (A4) platform began providing services to customers in Stuttgart in December 2020. This marks a major milestone in DT’s efforts building a state-of-the-art disaggregated broadband solution that blends open source and vendor proprietary components into a production-grade highly optimized solution for providing FTTx services.
A key foundational building block of A4 is ONF’s Virtual OLT Hardware Abstraction (VOLTHA) open source software controlled by the ONF’s ONOS SDN Controller and a set of ONOS Apps. This VOLTHA stack enables operators to extend software defined programming to the fixed access network, and makes it possible to embrace a best-of-breed approach to selection of white box network equipment. In addition to this open source stack, ONF’s SDN-Enabled Broadband Access (SEBA) Reference Design documents the architecture and framework used to assemble open solutions such as DT’s.
VOLTHA, operational in the A4 network, has been developed as a joint effort between ONF, ONF operator partners (particularly AT&T, Deutsche Telekom and Turk Telekom), and additional members and vendors in the VOLTHA ecosystem. The role of the operators is key in shaping the architecture and requirements for VOLTHA and SEBA with their sharing of insight learned in field trials and early commercial deployments. This collaboration has helped to improve, harden and scale VOLTHA and SEBA.
We want to also congratulate the ONF member companies that DT credited in their announcement, including: ADTRAN, BISDN, Broadcom, Radisys and Reply. Creating disaggregated solutions is a team effort, and it’s terrific to see how DT is building their next-generation solutions with an ecosystem of best-of-breed players.
