Communication method and device of slice packet network and electronic equipment

The invention discloses a communication method of a slice packet network, and aims to solve the problem that in the prior art, after a looped network is subjected to multiple fiber breaking faults or attacks, the interruption time of an SPN service is easily caused to be too long, so that the perception of a user is poorer. The method comprises the following steps: establishing communication connection between a first redundant service port of common convergence SPN equipment and a second redundant service port of backbone convergence SPN equipment in a slice packet network; the communication connection is used as an escape route of the slice packet network; judging whether an original route in the slice packet network fails or not; and when the original route of the slice packet network fails, starting the escape route, so that equipment on two sides of the escape route realizes route communication based on the escape route. The invention further discloses a communication method and device of the slice packe
