Network APIs such as UNIX sockets, DPDK, Netmap, etc. assume that networks provide only end-to-end connectivity. However, networks increasingly include smart NICs and programmable switches that can implement both network and application functions. Several recent works have shown the benefit of offloading application functionality to the network, but using these approaches requires changing not just the applications, but also network and system configuration. In this paper we propose Bertha, a network API that provides a uniform abstraction for offloads, aiming to simplify their use.
