The difference is that the online device is a device configured with an IP address and accessed to the DCN, and the online device is a device not configured with an IP address and not accessed to the DCN. The administration system is a device capable of assigning IP addresses to access devices.

As further shown in fig. 1b, in the following embodiments of this embodiment, a first device is also referred to as a device to be online, a second device is also referred to as a device to be online, and the first device and the second device may also be referred to as access devices, or may be referred to as an access device to be online or an access device to be online, respectively. The third device is also called a management and control system, or may also be called a management and control device or a control device, etc.

The following embodiments of the present invention are proposed based on at least the above system architecture.

The embodiment of the invention provides a data transmission method which is applied to first equipment. Fig. 2 is a first flowchart illustrating a data transmission method according to an embodiment of the present invention; as shown in fig. 2, the method includes:

step 101: the first equipment sends a first message to the second equipment through a Flexe, MTN or SPN overhead frame; the first message comprises a DCN channel identifier and related information used for equipment online;

step 102: the first device receives a third message from a third device through the second device, wherein the third message comprises a management IP address distributed by the third device for the first device;

step 103: the first device accesses a data communication network based on the management IP address.

In this embodiment, the first device transmits, through a FlexE, MTN, or SPN overhead frame, related information for on-line of the device, and transmits, to the third device (i.e., a management and control system) through the second device (the second device has a capability of processing and forwarding a message to the third device and an agent), the third device (i.e., the management and control system) allocates a management IP address to the first device, and transmits, to the first device, the allocated management IP address through the second device, and the first device can access a Data Communication Network (DCN) based on the management IP address, thereby implementing that the first device automatically acquires the management IP address and automatically accesses the Data Communication Network (DCN) based on the management IP address.

In this embodiment, the first message is marked by using a DCN channel identifier, and for example, the DCN channel identifier may be a special Virtual Local Area Network (VLAN) identifier, which is different from a normal service packet. The related information for the online of the device included in the first message includes information required in the automatic online of the device. Illustratively, the related information for the device to be online includes at least one of: MAC address, system name, system description information, IPv6 management address, IPv4 management address of the device. The related information for on-line of the device may further include device identification, device information, routing information, and the like. The device information and the routing information may be generated through Link Layer Discovery Protocol (LLDP) information or Open Shortest Path First (OSPF) Protocol.

In some optional embodiments of the invention, the first message is transmitted through a first lane of a FlexE overhead frame of a FlexE port, an MTN overhead frame of an MTN port, or an SPN overhead frame of an SPN port.

In this embodiment, the first device encodes the message into a 64-bit or 66-bit (64/66B) code block format, and transmits the message through a FlexE overhead frame of a FlexE port, an MTN overhead frame of an MTN port, or a first channel of an SPN overhead frame of an SPN port. Illustratively, after 64/66B encoding, the packet is inserted into a first channel of a FlexE overhead frame of a FlexE port, an MTN overhead frame of an MTN port, or an SPN overhead frame of an SPN port for transmission. Optionally, the first message is transmitted through 4 th and 5 th code blocks in an overhead frame. For example, taking an MTN overhead frame as an example, the first device may directly use a first channel of a Section (Section) layer in the MTN overhead frame for transmission. Illustratively, one MTN overhead frame includes 8 64/66bit blocks, one MTN overhead frame is inserted every 1023 MTN block blocks, and the first message is transmitted through the 4 th 64/66B code block and the 5 th 64/66B code block in the MTN overhead frame.

Illustratively, taking MTN as an example, the first device may transmit the DCN message through an MTN overhead or an MTN client (MTN client). When a first device accesses a network for the first time (namely the device is not on line), transmitting a message through an MTN overhead (namely a first channel); after the first device accesses the network (i.e. the device is online), the message may be transmitted through an MTN client (MTN client) or an MTN overhead.

In this embodiment, the second device is an online device, and the second device has the capability of processing and forwarding the message to the third device, and transmits the first message to the third device; the third device is a management and control system and can allocate a management IP address to the first device and transmit the management IP address to the first device through the second device through a third message. The first device may modify the IP address to the management IP address, and access the data communication network based on the management IP address.

In some optional embodiments of the invention, after the first device accesses the data communication network, the method further includes: the first device receives an instruction from the third device, and switches a second channel to transmit the DCN message based on the instruction.

In this embodiment, after the first device accesses the data communication network (that is, after the first device is online), the first device may be switched to the second channel to transmit the DCN message based on the instruction of the third device, or may be switched to an MTN client (MTN client) by the MTN overhead to transmit the DCN message. For example, the third device may have the capability of detecting whether the first device has a client (e.g., MTN client), that is, whether the first device is configured with a client (e.g., MTN client); if the third device detects that the first device has a client (e.g., an MTN client), that is, the first device is configured with the client (e.g., an MTN client), the third device may send an instruction to the first device, and the first device switches the second channel to transmit the DCN message based on the instruction.

For example, the DCN message of the present embodiment may include DCN channel identifier, protocol (e.g., path Computation Element Protocol (PCEP), link Layer Discovery Protocol (LLDP), open Shortest Path First (OSPF), telemetry Protocol, etc.), netconf Protocol configuration management interface, network Element capability, alarm, and so on.

In some optional embodiments of the invention, before the first device receives the instruction from the third device, the method further comprises: the first device sends an acknowledgement message associated with the second channel to the third device.

In this embodiment, if the first device has a client (e.g., an MTN client) or is configured with a client (e.g., an MTN client), the first device may send a confirmation message to the third device; the third device may send an instruction to the first device to switch channels based on the acknowledgement message.

In some optional embodiments of the invention, the method further comprises: and when the first equipment detects that the second channel is invalid or deleted, switching to the first channel to transmit the DCN message.

In this embodiment, for example, when the first device detects that a delivery channel (i.e., the second channel) Of the MTN client is deleted or fails, the first device may automatically switch to the first channel (e.g., MTN overhead) to transmit the DCN message according to locally generated notification information, for example, a LOSs Of Signal (LOS) alarm, a performance degradation alarm, and the like.
