Abstract:
1. A method for ensuring service classes of packet services, wherein each Resilient Packet Ring (RPR) station of an RPR network performs the following process, respectively: limiting the rate of services with different service classes uploaded to a ringlet from the RPR station, respectively, in accordance with the RPR physical packet lengths, wherein the RPR physical packet length is the sum of the length of an RPR packet and the length of an RPR physical layer encapsulation overhead; and obtaining a statistic rate of all non-class A0 services forwarded by the RPR station and uploaded to the ringlet from the RPR station, wherein in the process of making rate statistics, the length of the RPR physical layer encapsulation overhead of the sent packet is added to the statistic rate of all non-class A0 services each time after or before forwarding a packet of non-class A0 service, and the length of the RPR physical layer encapsulation overhead of the sent packet is added to the statistic rate of all non-class A0 services each time after or before transmitting the packet of the non-class A0 service uploaded to the ringlet from the RPR station, when the statistic rate of the non-class A0 services exceeds the un-reserved rate of the RPR network, reporting a congestion message and adjusting the statistic rate of non-class A0 services uploaded to the ringlet within a congestion domain.
