In a method for guaranteeing classification of service of the packet traffic, each node on the Resilient Packet Ring performs the following steps separately. For the traffic of the different classification of service going to the ring at this node, performing rate restriction according to the physical packet length of the Resilient Packet Ring of the various classification of service traffic separately; for all the non-class A0 traffic transmitted by this node and gone to the ring at this node, performing rate monitoring according to the physical packet length of the Resilient Packet Ring of the various classification of service traffic in real time. Also, in a method of rate restriction according to the total length of the encapsulated message in the transmitted message based on the token bucket, rate restriction and rate monitoring is performed for the traffic going to the ring at this node according to the physical packet length of the Resilient Packet Ring, overcoming the default that doesn't assure the preserved bandwidth previously because the encapsulation spending of the physical layer result in the transmitted traffic preempting the bandwidth of the traffic going to the ring in the lower node in the network of the Resilient Packet Ring.
