a sending unit, configured to send the TCP request packet to a backend system corresponding to the target service type;
the analyzing the TCP request message based on the preset first configuration table to obtain the characteristics of the TCP request message includes:
acquiring the format of the TCP request message;
acquiring a first characteristic corresponding to the format of the TCP request message based on the first configuration table;
the first configuration table comprises a corresponding relation between a message format and a first characteristic;
the obtaining, by a preset second configuration table, a target service type corresponding to a characteristic of the TCP request packet includes:
determining a candidate service type corresponding to the first characteristic based on the preset second configuration table;
judging whether the first characteristic meets the distribution rule of the candidate service type or not according to the priority of the candidate service when a plurality of candidate service types exist;
when the TCP request message is detected to meet a first candidate service type, taking the first candidate service type as a target service type; the first candidate service type is any one of the candidate service types.
