The present invention discloses a protection method based on the Ethernet at the optical network port level; the method comprises the following steps that a first veneer and a second veneer are separately connected with a first port and a second port for network equipment protection and the first and second veneers are collocated with the same information and a protection unit is arranged betweenthe first and second veneers in the S102 step; a cross board is equipped with a 1 plus 1 time slot channel protection and a priority from the first and second veneers to the cross board in the S104 step; when the user side of the first veneer fails, the priority of the cross board is alternated to trigger the rotation of the 1 plus 1 time slot on the cross board and switch the operation to the second veneer in the S106 step; when the system side of the first veneer fails, the equipment for network protection is used to switch the operation from the first port to the second one in the S108 step. The present invention realizes the port-level protection of the Ethernet operation on the optical transmission MSTP device and forms the complete network protection with the existent SDH channel protection technology.
Description
technical field [0001] The invention relates to the technical field of network communication, in particular to a data access technology in the field of (communication) SDH (Synchronous Digital Hierarchy) optical transmission. Background technique [0002] Multi-Service Transport Platform MSTP (Multi-Service Transport Platform) has been accepted by many telecom operators. With its low cost, high reliability and smooth upgrade capability, it has become an important device for constructing a metropolitan area network. As the application of MSTP Ethernet data boards becomes more and more widespread, operators put forward higher requirements for the security of access data. [0003] The current SDH1:N protection can realize single-board failure protection and manual switching; however, there is a big defect for data single boards, that is, the SDH1:N protection function cannot provide protection for user-side connections, let alone GE ports. for protection. Therefore, protecti...
