• Low-level, high-efficiency programming for subset of system SW that represents bulk of workload and is worth a lot of optimization. • Fast-path offload of a router stack (like a SW ASIC) • Layer 2 and up in a cell base station • Software fed by bump-in-wire net stack (like IPSEC), often with specialcase assumptions allowed because network is controlled. Linux Bare Metal Style SW core core core core TM Linux core core core core core 6 Bare metal software migrates from running alongside Linux on its own cores to running within a Linux user space process Bare Metal Style SW core Not really intended for legacy user space applications, but there is interest in this.
