Summary • ONF: Operator driven curated open source • • CORD is the flagship umbrella project SEBA – SDN Enabled Broadband Access built on the CORD platform • Modular Components: • • VOLTHA abstracts the PON as a quasi-Ethernet switch to the SDN controller Trellis manages a multi-purpose leaf-spine fabric • SEBA & 5 G • • MWC Barcelona 2018: SPGW in hardware using Trellis + P 4 MWC Barcelona 2019: SEBA + OMEC + 5 G high-split RAN 5 G low-split RAN on PON discussed by ORAN and ITU-T – a few years away SEBA + Terragraph – mm. Wave backhaul – more near term
