On my Ubuntu 16.04 Linux desktop computer I see a non-stop traffic in Wireshark about two protocols MDNS and BJNP. See: https://i.imgur.com/wbOcpzO.png

What are those two protocols and how to get rid of the non-stop traffic? Thanks

Both these protocols are LAN service discovery protocols (MDNS = multicast DNS, BJNP is a prorietary protocol by Canon). Up to their payload some application running on your Ubuntu is searching for any scanner possibly connected to your LAN. You can get rid of this traffic either actually, by disabling that application (or daemon), or just prevent them from being captured by setting a capture filter saying "don't capture UDP packets to/from ports 5353 and 8612.
