<p>A ring-based packet transmitting method, network system and node equipment are provided. The ring-based packet transmitting method includes the following steps: a received user packet is encapsulated; one or more PBB or PBT rings are detected for fault; when a fault is detected, a PBB or PBT ring having no fault is selected to send the encapsulated packet to a target node equipment according to a corresponding relation between virtual media access control (VMAC) addresses and ports. The network system includes at least two node equipments interconnected with one or more node equipments respectively through ports provided thereon to form one or more PBB or PBT rings. The node equipment includes at least two ports and a data processing unit. Thus, packet transmission on the PBB or PBT ring is achieved.</p> |
