An Ethernet transmission apparatus having a quick protection and fair attribute as well as a corresponding method are disclosed. The apparatus comprises a sorter (1), MPLS processing module (2) and a SDH processing module (3), wherein, the MPLS processing module includes a VC tag packaging unit (21), a multiplexing unit (22), a tag managing unit (23), a scheduler (24), an MPLS protective unit (25), an MPLS signaling unit (26) and a Fair algorithm unit (27). The present invention sorts the Ethernet transactions and labels VC tags by the VC tag packaging unit so as to form a PW LSP. PW LSP with a plurality of identical source and target ends are multiplexed into a tunnel LSP. MPLS signaling unit counts the network nodes that LSP passes by and calculates a protective LSP. MPLS protective unit selects an active LSP or a protective LSP and enters the scheduler for queuing. The FAIR algorithm controls the allotment of the bandwidth so as to secure the fairness of the transactions. <IMAGE> |
