Service function chain mapping system and method based on information interaction connection duration optimization

The invention discloses a service function chain mapping system and method based on information interaction connection duration optimization. In the calculation process, the influence of vehicle node movement on information interaction communication duration is considered, a service component node sorting method is designed, and feasible judgment is carried out on node attributes, node calculation units, structures and link capacity in node mapping according to a sequence; and the physical network node with the maximum information interaction connection duration is preferentially selected for mapping. According to the method, the component mapping with the maximum information interaction connection duration can be realized with relatively low calculation complexity. According to the method, the influence of vehicle mobility on information interaction communication duration after service function chain mapping can be reflected, the feasible duration of service in a dynamic environment is increased, and the ser
