Meta Networking at the 2026 OCP Global Summit: Open Innovation for Scale-Up, Scale-Out, and Scale-Across AI Networks

At the 2026 OCP Global Summit, Meta presented networking work supporting its AI models and gigawatt-scale Prometheus cluster, including the liquid-cooled IcePack/IceCube rack with 102.4T switch blades, the Flattened Planar Fabric for scale-out, BAG super-spine and SRv6 backbones for scale-across, and Tahan, an Ethernet scale-up switch for MTIA 300. Meta also introduced OSPA, an OCP initiative co-led with Microsoft and Alibaba to standardize the switch platform layer with a v1.0 spec submitted to OCP, and said its MetaRoCE RDMA transport is going open source, starting with a user-space version on GitHub. Recorded talks and slide decks from the event are available on the 2026 OCP Global Summit website.
