Provided is a communication processing system including a response time measuring unit, a routing unit, and a communication route setting unit. The response time measuring unit measures a response time on a communication route between one or more communication apparatuses. The routing unit controls a communication route between the one or more communication apparatuses, based on the first communication route information to which a communication route between communication apparatuses is set. The communication route setting unit sets, based on the measured response time, a first communication route on which communication data related to a certain communication between communication apparatuses is transferred, to the first communication route information. The communication route setting unit sets, a communication route being different from the first communication route, on which communication data related to a communication other than the certain communication is transferred, to the first communication route in
