Abstract (in Japanese) (See Japanese page) 
(in English) MQTT is a major communication protocol for the IoT. In MQTT, all communication is done through a server called a "broker". Therefore, there is a concern that the broker is overloaded. In this study, we focus on MQTT-SN which is based on UDP and propose a method to offload the processing of the broker into the network using P4. P4 is a language for data plane programming, and the proposed method reduces the load on the broker by delivering publish messages that satisfy certain conditions directly from the network switch to the corresponding subscribers. We implemented the proposed method in BMv2, a reference implementation of P4, and conducted evaluation experiments. The experimental results show that the proposed method can reduce the number of packets that reach the broker. In addition, we confirmed that the proposed method reduces the delay time by more than 40% when sending a 100 Byte publish message.
