[0003] Regardless of the wrapping switching mode or the steering switching mode, when the upper-ring service node or the lower-ring service node in the ring network fails, or the upper-ring service node or the lower-ring service node is isolated due to a peripheral fault, the The following problem: the service cannot be connected normally, but the MPLS ring network protection still starts switching, resulting in the traffic of the unreachable service still being forwarded on each node of the ring network, occupying the bandwidth of other services that can be connected normally

[0116] Optionally, the second suppression unit 902b is specifically configured to determine the ring channel corresponding to the suppressed service according to the suppressed service, and suppress the service transmitted through the ring channel. In one implementation manner, the second suppression unit 902b suppresses the services transmitted by the ring channel by setting an invalid flag at the ring channel forwarding layer and discarding the services forwarded to the ring channel.
[0117] Figure 16 Is a schematic structural diagram of a network device provided by an embodiment of the present invention, such as Figure 16 As shown, the network device includes a processor 1601. The processor 1601 is used to obtain unreachable node information, determine the suppressed service in the local service information according to the unreachable node information, and suppress the determined suppressed service.

The invention provides a service processing method and network equipment for a ring network. The method comprises the following steps of: acquiring unreachable node information by a first node in the ring network; according to the acquired unreachable node information, determining a suppressed service in local service information; and suppressing the determined suppressed service. The network equipment comprises an acquisition module, a determination module and a suppression module. An unreachable service is suppressed, so that an additional protecting channel bandwidth can be prevented from being occupied, and influence on other reachable services is maximally reduced.
Description
Technical field [0001] The invention relates to communication technology, in particular to a business processing method and network equipment in a ring network. Background technique [0002] With the development of Multi Protocol Label Switching (MPLS) technology, in order to enhance the reliability of the network, a variety of MPLS ring network protection methods have gradually emerged, each of which can include wrapping switching. And steering switch mode. For example, when the ring network is working normally, the transmission path of the service in the ring network is as follows: Figure 1a Shown. When a fault occurs between node 4 and node 3 in the ring network, the wrapping switching method will follow Figure 1b The path shown by the dotted line is switched, and the steering switching method will be Figure 1c The path shown by the dotted line is switched. [0003] Regardless of the wrapping switching mode or the steering switching mode, it will occur when the upper ring se...
