Message transmission method and device, nonvolatile storage medium and electronic equipment

The invention discloses a message transmission method and device, a nonvolatile storage medium and electronic equipment. The method comprises the steps that a preset switch obtains an original message and a first telemetering message, the original message comprises a message header and a message body, the message header is used for indicating a message forwarding path of the original message in an in-band network telemetering domain, and the in-band network telemetering domain comprises a plurality of preset switches; the message headers of the first telemetering message and the original message are the same; inserting in-band network telemetering data of a preset switch into a message main body of the first telemetering message to generate a second telemetering message; and respectively transmitting the original message and the second telemetering message according to the message header. According to the invention, the technical problem of low transmission efficiency of the second telemetering message is sol
