Abstract:

With the continuous improvement of network speeds, the network processing overhead becomes increasingly significant. The in-network computing technology has become a key technology to offload the burden of hosts, release computing power of server, and solve network bottlenecks, which has attracted much attention in the fields of cloud computing and edge computing. First, starting with the needs of in-network computing, the background of in-network computing is described. Then, the development and industrialization of in-network computing technology is sorted out by focusing on the two aspects, namely, programmable switch and smart Network Interface Card (NIC). Finally, the application prospect of in-network computing is analyzed, and the application scenarios and the application value are proposed.

Key words: in-network computing, smart NIC, Data Processing Unit, programmable switch
