The embodiments of the present invention provide a method for detecting multi-service performance in tunnel, which includes the following features: receiving detecting packets corresponding to the service packets, wherein the priorities of the detecting packets are the same as those of the corresponding service packets and the detecting packets include at least one of the loss packet detecting parameter, time delay detecting parameter and jittering detecting parameter; detecting service performance in tunnel according to the detecting parameters in the detecting packets. The embodiments of the present invention implement performance detecting for the services transmitted in tunnel by setting the same priorities of the detecting packets as those of the corresponding service packets and adding at least one of the loss packet detecting parameter, time delay detecting parameter and jittering detecting parameter to the detecting packets, and thereby solve the problem of the prior art that the performance detecting for different services transmitted in tunnel can not be implemented.
