The present invention provides a method, a network device, and a network system for processing a data service. The method for processing a data service includes: receiving a data service packet; identifying protocol information and/or service information of the packet; mapping the protocol information and/or service information to a corresponding type of service field, and changing a type of service value of the packet according to the mapped-to type of service field; and performing queue scheduling for the packet according to the type of service value of the packet. The present invention effectively reduces the cost of the QoS implementation solution, prevents a low-priority application server from forging high-priority services, and prevents a high-priority port from being used to bear low-priority services.
