OpenURMA: A Clean-Room Open Implementation of the Unified Bus Protocol
OpenURMA is the first open-source implementation of Huawei's Unified Bus (UB) protocol, a 2025 specification designed to overcome RDMA bottlenecks at the network interface. The implementation demonstrates 4.37x lower latency and 2.80x higher throughput compared to RoCEv2, while consuming only 14% of FPGA resources, offering a potential architectural shift for datacenter networking.
