The significance of the order of application protocols: (1) First, the order has an impact on the sequence in the application protocol view, but Others always remains in the end. (2) Second, for the smelling-based application protocols, this order also determines the priority of smelling, such as there is a packet meet the smelling rules of two protocols, then the packet would be recognized as the traffic of the protocol arranged at top.
