Abstract
Enhanced Common Packet Radio Interface (eCPRI) based Fronthaul forms the foundation for open radio access network (O-RAN). O-RAN envisages splitting the radio into two parts, a Distributed Unit (DU) and Radio Units (RU), interconnected using high speed Fronthaul links. O-RAN and eCPRI for 5G/NR place demands for high speed Fronthaul with low latency, and high network bandwidth requirements. In the present disclosure, embodiments for configurable eCPRI Fronthaul solutions are disclosed. Various hardware accelerator implementations are presented for control plane and user plane traffic. The hardware accelerator implementation may support DU and RRU functionality required by eCPRI with minimal software intervention. The configurable eCPRI Fronthaul may support different data flows and meet different performance demands of DU and RRU. Scalable architecture may be applied for the configurable eCPRI Fronthaul to allow stacking of multiple hardware accelerators via a high-speed network interconnect, and overall performance and throughput may be improved.
