At the 2026 OCP Global Summit, Meta announced several open networking infrastructure innovations: IcePack, its first liquid-cooled network rack; IceCube, a 102.4 Tbps switch blade delivering 128×800G non-blocking capacity; Flattened Planar Fabric (FPF), a multiplane backend scale-out fabric; MetaRoCE, an open-source RDMA transport protocol; and the Open Switch Platform Architecture (OSPA) initiative co-led with Microsoft and Alibaba. Meta also shared details on petabit-scale backend aggregation for multi-site clusters and Ethernet-based scale-up networking for its MTIA 300 system.
