The transmission module is used for sending a third message sent by the second management message processing module to the main control card, and the main control card is used for generating a fourth message according to the third message sent by the transmission module, wherein the fourth message is the third message added with the remote management information.

The following describes a communication method provided by the embodiment of the present invention with reference to the communication system shown in fig. 1 and the office device 100 shown in fig. 2.
As shown in fig. 3, the communication method provided by the embodiment of the invention includes:
s301, a message forwarding module in the local side equipment 100 receives a message sent by the remote side equipment.
The message forwarding module may be represented by a message forwarding (packet transmission, PT) module. The PT module is used for carrying out data interaction between the Ethernet service side and the management end and between the management end and the remote equipment, and consists of a plurality of message forwarding channels.
S302, a first management message processing module in the local side equipment 100 extracts a first message from a message forwarding module in the local side equipment 100.
The first message is a management message with a single layer VLAN tag and an outer layer VLAN tag as a first value.
The first management message processing module may be represented by management message processing (management packet pro cess, MPP) 1. The MPP1 module is used for extracting management messages and packaging the management messages, and in practical application, the MPP1 module sets VLAN values of the management messages to be extracted aiming at forwarding channels of the PT module and is used for distinguishing interaction between the management messages on different message forwarding channels and the MPP1 module. Here, it is explained that the management VLAN tag corresponding to each packet forwarding channel may not be the same by the MPP1 module, so as to distinguish the channel corresponding to the packet forwarding, and is different from the service VLAN tag.
The MPP1 module can be realized by a field programmable gate array (field-programmable gate arra y, FPGA), and the message packaged by the MPP1 module is secondarily packaged according to a remote management design rule.
S303, a first management message processing module in the local side equipment 100 generates a second message according to the first message.
The second message is a management message having a double-layer VLAN tag, and both the outer-layer VLAN tag and the inner-layer VLAN tag are the first numerical value.
Specifically, the MPP1 module extracts the first message to a corresponding message encapsulation processing unit queue in the MPP1 module. The message packaging processing unit of the MPP1 module extracts VLAN tag in the first message by identifying VLAN tag field in the first message, copies the field and inserts the field into the original first message, and packages the original single-layer VLAN tag management message into double-layer V LAN tag management messages with the same VLAN tag of the inner layer and the outer layer.
S304, the first management message processing module in the local side device 100 sends a second message to the second management message processing module in the local side device 100.
Correspondingly, a second management message processing module in the office device 100 receives the second message.
S305, a second management message processing module in the local side equipment 100 generates a third message according to the second message sent by the first management message processing module in the local side equipment 100.
The third message is a management message with a double-layer VLAN tag, wherein the outer-layer VLAN tag is a second numerical value, and the inner-layer VLAN tag is a first numerical value. The second management message processing module may be represented by MPP 3.
Specifically, after receiving the second message sent by the MPP1 module, the MPP2 module identifies an outer layer VLAN tag in the management message, and replaces the outer layer VLAN tag with a VLAN tag1 identifiable by the main control card.
S306, the second management message processing module in the local side device 100 sends a third message to the transmission module in the local side device 100.
Correspondingly, the transmission module in the office device 100 receives the third message.
S307, the transmission module in the local side device 100 sends a third message sent by the second management message processing module in the local side device 100 to the master control card in the local side device 100.
Correspondingly, the master control card in the local side device 100 receives the third message.
Alternatively, the transmission modules in the office device 100 may include a first transmission module (transmission module 1) and a second transmission module (transmission module 2).
In the prior art, the transmission module 1 and the transmission module 2 correspond to different VLAN forwarding domains respectively. For example, transport module 1 corresponds to VLAN forwarding domain 1 and transport module 2 corresponds to VLAN forwarding domain 2. In the embodiment of the present invention, VLAN forwarding domains of the transmission module 1 and the transmission module 2 may overlap. For example, transport module 1 corresponds to VLAN forwarding domain 1, transport module 2 corresponds to VLAN forwarding domain 1 and VLAN forwarding domain 2.
In order to increase the reliability of remote management, the embodiment of the invention adds a protection mechanism on the basis of the method. In the embodiment of the invention, in the prior art, specific type message timing interaction is added between the transmission module 1 and the transmission module 2, the setting of the main and standby roles positioning and the management message forwarding domain is carried out, and the transmission module 2 is multiplexed and used as a standby channel of the transmission module 1. After the management message enters the transmission module, the main transmission module notifies the standby transmission module of own state information, and the format of the interactive message is shown in table 1.
TABLE 1
| Message type | Operating state | Character status | Managing message VLAN forwarding domain |
In the initial state, the transmission module 1 is used for forwarding the remote management message in the embodiment of the present invention, and the preset role is mainly in a working state, and supports the VLAN forwarding domain 1. The transmission module 2 is used for forwarding other management messages, and is preset to be in a non-working state, and the VLA N forwarding domain 2 available for transmission is not overlapped with the VLAN forwarding domain 1 supported by the far end in the embodiment of the present invention.
During normal transmission, the transmission module 1 is in a working state and takes the role as the main part. Normal remote management message transmission is performed, and status information is sent to the transmission module 2 at regular time. When the transmission module 2 receives the message of the message type, the message interpretation is carried out, the management message VLAN carried in the message is extracted, and if the transmission module 1 is in a working state and the role state is the main state, the response processing is not carried out, and the transmission of the management message is carried out according to the initial state.
At a certain moment, when the transmission module 1 detects that the current state is in the non-operating state, the transmission module 1 modifies the state information to be in the non-operating state, takes the role as a backup, transmits the information to the transmission module 2 no matter whether the timing time is reached or not, and stops transmitting the exchange message during the state.
After receiving the state change information of the transmission module 1, the transmission module 2 modifies the role information of itself to be the main role information and updates the role information to be the working state. Meanwhile, the received VLAN forwarding domain 1 is added into the forwarding domain of the VLAN forwarding domain, and the processing of the remote management message in the embodiment of the invention is increased. And sends a timing interaction message to the transmission module 1 for state information notification.
According to the method, the transmission module 2 can be reused only by adding small message interaction, so that the utilization rate of the transmission module 2 is increased, and the stability of the management capability of the remote equipment is improved.
