A backplate, a method and device for analysing a message, and a method and device for implementing communications. The backplate comprises one or more than one backplate slot positions and an interface for transmitting a data message; each backplate slot position comprises a main internet access and a standby internet access; one end of the standby internet access is connected to the interface; and one end of the main internet access and the other end of the standby internet access are respectively connected to different ports of a switch chip of a service single board. By means of the technical solution, a standby internet access is added to the backplate slot position, so that when the main internet access fails, the main internet access can be rapidly switched to the standby internet access, thereby guaranteeing that a service single board can implement a service normally when the main internet access fails. |
