Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a data transmission method, device, system and communication equipment. Background Art

[0002] With the advancement of transmission network technology, the number of Packet Transport Network (PTN) devices has reached 2 million, with over 100,000 miniaturized access devices deployed annually. Slicing Packet Network (SPN) networks are also entering large-scale commercial use in the 5G era. However, the initial installation and configuration of these devices is a critical factor hindering the development of existing network services.

[0003] Currently, most equipment is initially installed on-site, typically requiring application, communication, and confirmation with the installation department. On the transmission equipment side, after installation, manual login is required to determine the station address or location of the online equipment. Furthermore, the Internet Protocol (IP) address must be manually configured before the equipment can be connected to the Data Communication Network (DCN). This makes the equipment online process complex. Currently, there is no effective solution for automated equipment online. Summary of the Invention

[0058] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0059] Figure 1a and Figure 1b Schematic diagram of the system architecture of the data transmission method according to the embodiment of the present invention; Figure 1a As shown, the network may include a management and control system, access devices, one or more online devices, and one or more devices to be online. Access devices can be connected to the management and control system via a DCN (or an external DCN). Both online devices and devices to be online are access devices in the network. The difference is that online devices are configured with IP addresses and connected to the DCN, while devices to be online are not configured with IP addresses and are not connected to the DCN. The management and control system is the device that can assign IP addresses to access devices.

[0060] Further integration Figure 1b As shown, in this embodiment and the following embodiments, the first device is also referred to as a device to be put online, and the second device is also referred to as an online device. The first device and the second device can also be referred to as access devices, or as access devices to be put online or online access devices, respectively. The third device is also referred to as a management and control system, or can also be referred to as a management and control device or a control device, etc.

[0061] The following embodiments of the present invention are proposed based at least on the above system architecture.

[0062] An embodiment of the present invention provides a data transmission method, which is applied to a first device. Figure 2 FIG1 is a flow chart of a data transmission method according to an embodiment of the present invention; FIG2 is a flow chart of a data transmission method according to an embodiment of the present invention; Figure 2 As shown, the method includes:

[0063] Step 101: A first device sends a first message to a second device via a FlexE, MTN, or SPN overhead frame; the first message includes a DCN channel identifier and related information for the device to go online;

[0064] Step 102: The first device receives a third message from a third device through the second device, where the third message includes a management IP address allocated by the third device to the first device.

[0065] Step 103: The first device accesses the data communication network based on the management IP address.

[0066] In this embodiment, the first device transmits relevant information for the device to go online through FlexE, MTN or SPN overhead frames, and transmits it to the third device (i.e., the management and control system) through the second device (the second device has the ability to process and forward messages to the third device and act as an agent). The third device (i.e., the management and control system) assigns a management IP address to the first device, and transmits the assigned management IP address to the first device through the second device. The first device can access the data communication network (DCN) based on the management IP address, thereby enabling the first device to automatically obtain the management IP address and automatically access the data communication network (DCN) based on the management IP address.

[0067] In this embodiment, the first message is marked with a DCN channel identifier. Exemplarily, the DCN channel identifier can be a special virtual local area network (VLAN) identifier, etc., to distinguish it from ordinary business messages. The relevant information for the device to go online included in the first message includes the information required for the device to go online automatically. Exemplarily, the relevant information for the device to go online includes at least one of the following: the device's MAC address, system name, system description information, IPv6 management address, and IPv4 management address. The relevant information for the device to go online can also include a device identifier, device information, routing information, etc. Among them, the device information and routing information can be generated through Link Layer Discovery Protocol (LLDP) information or Open Shortest Path First (OSPF) protocol, etc.

[0068] In some optional embodiments of the present invention, the first message is transmitted through a first channel in 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.

[0069] In this embodiment, the first device encodes the message into a 64-bit or 66-bit (64 / 66B) code block format and transmits it through the first channel of the FlexE overhead frame of the FlexE port, the MTN overhead frame of the MTN port, or the SPN overhead frame of the SPN port. Exemplarily, after the message is 64 / 66B encoded, it is inserted into the first channel of the FlexE overhead frame of the FlexE port, the MTN overhead frame of the MTN port, or the SPN overhead frame of the SPN port for transmission. Optionally, the first message is transmitted through the 4th code block and the 5th code block in the overhead frame. Exemplarily, taking the MTN overhead frame as an example, the first device can directly use the first channel of the section layer in the MTN overhead frame for transmission. Exemplarily, an MTN overhead frame includes 8 64 / 66bit blocks, and an MTN overhead frame is inserted every 1023 MTN blocks. The above-mentioned first message is transmitted through the 4th 64 / 66B code block and the 5th 64 / 66B code block in the MTN overhead frame.

[0070] For example, using MTN as an example, the first device can transmit DCN messages via the MTN overhead or MTN client. When the first device first accesses the network (i.e., the device is not online), the message is transmitted via the MTN overhead (i.e., the first channel). After the first device accesses the network (i.e., the device is online), the message can be transmitted via the MTN client or MTN overhead.

[0071] In this embodiment, the second device is an online device capable of processing and forwarding messages to a third device, and transmits the first message to the third device. The third device is a management and control system capable of assigning a management IP address to the first device and transmitting the management IP address to the first device via the second device via a third message. The first device can modify its IP address to the management IP address and access the data communication network based on the management IP address.

[0072] In some optional embodiments of the present invention, after the first device accesses the data communication network, the method further includes: the first device receiving an instruction from the third device, and switching the second channel to transmit the DCN message based on the instruction.

[0073] In this embodiment, after the first device accesses the data communication network (i.e., after the first device goes online), it can switch to the second channel for DCN message transmission based on an instruction from a third device. This means that DCN message transmission can be switched from the MTN overhead to the MTN client (MTN client). For example, the third device can be capable of detecting whether the first device has a client (e.g., an MTN client), that is, detecting whether the first device has been configured as a client (e.g., an MTN client). If the third device detects that the first device has a client (e.g., an MTN client), i.e., the first device has been configured as a client (e.g., an MTN client), the third device can send an instruction to the first device, and the first device, based on the instruction, switches to the second channel for DCN message transmission.

[0074] Exemplarily, the DCN message of this embodiment may include a DCN channel identifier, a protocol (such as Path Computation Element Protocol (PCEP), Link Layer Discovery Protocol (LLDP), Open Shortest Path First (OSPF) protocol, Telemetry protocol, etc.), a Netconf protocol configuration management interface, network element performance, alarms, and the like.

[0075] In some optional embodiments of the present invention, before the first device receives the instruction from the third device, the method further includes: the first device sending a confirmation message related to the second channel to the third device.

[0076] In this embodiment, if the first device has a client (such as an MTN client) or is configured as a client (such as an MTN client), it can send a confirmation message to the third device; the third device can send an instruction for switching channels to the first device based on the confirmation message.

[0077] In some optional embodiments of the present invention, the method further includes: when the first device detects that the second channel is invalid or deleted, switching to the first channel to transmit the DCN message.

[0078] In this embodiment, illustratively, when the first device detects that the transmission channel (i.e., the second channel) of the MTN client is deleted or invalid, the first device can automatically switch to the first channel (e.g., the MTN overhead) to transmit the DCN message based on locally generated notification information, such as a loss of signal (LOS) alarm or a performance degradation alarm.

[0079] Based on the above embodiment, an embodiment of the present invention further provides a data transmission method, which is applied to a second device. Figure 3 Schematic diagram of the data transmission method according to an embodiment of the present invention Figure 2 ;like Figure 3 As shown, the method includes:

[0080] Step 201: A second device receives a first message from a first device; the first message is carried via a FlexE, MTN, or SPN overhead frame; the first message includes a DCN channel identifier and related information for the device to go online;

[0081] Step 202: The second device generates a second message based on the identification information of the second device, the relevant information for the device to go online, and the neighbor information related to the first device, and sends the second message to the third device;

[0082] Step 203: The second device receives the third message from the third device and forwards the third message to the first device. The third message includes the management IP address allocated by the third device to the first device, and the management IP address is used by the first device to access the data communication network.

[0083] In this embodiment, the second device is an online device. If the second device is the first access device in the data communication network, it can be connected to the data communication network by manually configuring a management IP address.

[0084] In this embodiment, the first message is marked with a DCN channel identifier. Exemplarily, the DCN channel identifier can be a VLAN identifier, etc., to distinguish it from ordinary service messages. The relevant information included in the first message for device online includes information required for the device to automatically go online. Exemplarily, the relevant information for device online includes at least one of the following: the device's Media Access Control (MAC) address, system name, system description information, IPv6 management address, and IPv4 management address. The relevant information for device online can also include a device identifier, device information, routing information, etc. The device information and routing information can be generated using LLDP information or the OSPF protocol.

[0085] In this embodiment, the first message is transmitted through a first channel in 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.

[0086] In this embodiment, the second device is similar to the first device and can also transmit DCN messages via an MTN overhead or MTN client. The second device is an online device and can send a second message to a third device via a second channel (e.g., an MTN client). The second channel is identified by a DCN channel identifier; exemplarily, the DCN channel identifier can be a special virtual local area network (VLAN) identifier to distinguish it from ordinary service messages.

[0087] In some optional embodiments of the present invention, the method further includes: the second device determining whether the first device is a registered neighbor node; if the first device is a registered neighbor node, obtaining neighbor information related to the first device.

[0088] In this embodiment, the second device may extract and decode the first message and then locally check whether it is a registered neighbor node. For example, the second device may search for locally stored neighbor information corresponding to the MAC address carried in the first message. If the locally stored neighbor information corresponding to the MAC address is present, it indicates that the first device is a registered neighbor node, and the second device obtains the neighbor information related to the first device. Conversely, if the locally stored neighbor information corresponding to the MAC address is not present, it indicates that the first device is an unregistered neighbor node.

[0089] In some optional embodiments of the present invention, the method further includes: if the first device is an unregistered neighbor node, assigning a neighbor identifier to the first device, and generating neighbor information related to the first device; wherein the neighbor information includes at least one of the following: the port index of the second device, the index of the first device, the first device identifier, the connection port identifier of the first device, the IP address of the first device, the IPv6 management address of the first device, the IPv4 management address of the first device, the system name of the first device, and the system description information of the first device.

[0090] In this embodiment, the second device generates a second message based on the second device's identification information, the relevant information for the device online, and the neighbor information related to the first device. Exemplarily, the second device's identification information may include information such as the second device's IP address and port identifier. Exemplarily, the second message may include two parts: a first part containing the content of the first message, such as the content shown in Table 1, and a second part containing the neighbor information, such as the content shown in Table 2.

[0094]

[0095]

[0096] In the above Table 2, "this end" refers to the second device, and "opposite end" refers to the opposite end relative to the second device. In this embodiment of the present invention, the "opposite end" is the first device.

[0097] In Table 2 above, the IPv6 management address (management-address-ipv6) and IPv4 management address (management-address-ipv4) are initial addresses before the device goes online. The initial addresses can be generated based on the device's MAC address.

[0098] For example, taking the generation of IPv6 management address from MAC address as an example, the IPv6 management address has a total of 128 bits. The first 64 bits can be filled with 0, and the last 64 bits can be mapped according to the MAC address. For example, the first 48 bits of the last 64 bits are mapped to the MAC address, and the last 16 bits of the last 64 bits are filled with 1.

[0099] In this embodiment, after the third device assigns a management IP address to the first device, the second device receives a third message from the third device. The second device also has a proxy function, including but not limited to Telnet, Transmission Control Protocol (TCP) Layer 4 channel, and NetconfClient. Exemplarily, the second device establishes a temporary channel between the third device and the first device via a local TCP port and maps the operating port of the Netconf server on the first device to the local server on the third device. The third device communicates with the remote Netconf server on the first device by accessing the locally mapped port, thereby sending the management IP address to the first device.

[0100] Based on the above embodiment, an embodiment of the present invention further provides a data transmission method, which is applied to a third device. Figure 4 Schematic diagram of the data transmission method according to an embodiment of the present invention Figure 3 ;like Figure 4 As shown, the method includes:

[0101] Step 301: A third device receives a second message from a second device, where the second message includes: identification information of the second device, relevant information for the first device to go online, and neighbor information related to the first device;

[0102] Step 302: The third device allocates a management IP address to the first device, and sends a third message including the management IP address to the first device through the second device. The management IP address is used for the first device to access a data communication network.

[0103] In this embodiment, the third device is a management and control system, or may also be referred to as a management and control device, a control device, etc. After receiving the second message, the third device creates a new network element for the first device and allocates a management IP address to the first device according to the address planning rules. Exemplarily, the third device extracts the identification information of the second device carried in the second message (such as an IP address, a port identifier, etc.) to query the geographical location of the second device and allocates a management IP address to the first device based on the geographical location. The second message is marked with a DCN channel identifier. Exemplarily, the DCN channel identifier may be a VLAN identifier, etc., to distinguish it from ordinary service messages.

[0104] Exemplarily, the relevant information for the device to go online includes at least one of the following: the device's media access control MAC address, system name, system description information, IPv6 management address, and IPv4 management address.

[0105] Exemplarily, the neighbor information related to the first device includes at least one of the following: the port index of the second device, the index of the first device, the first device identifier, the connection port identifier of the first device, the IP address of the first device, the IPv6 management address of the first device, the IPv4 management address of the first device, the system name of the first device, and the system description information of the first device.

[0106] In some optional embodiments of the present invention, the third device assigns a management IP address to the first device, including: the third device determines the area range to which the second device belongs based on the identification information of the second device, and assigns a management IP address to the first device from the corresponding management IP address set based on the area range.

[0107] In this embodiment, the third device pre-configures and manages the IP address set according to the regional scope. Figure 5 This is an example diagram of the management IP address in an embodiment of the present invention, such as Figure 5As shown, the management IP address includes 4 / 8 bits representing the region or network level identifier, which corresponds to the corresponding regional range. The third device then queries the geographic location of the second device according to the identification information of the second device (such as the IP address, port identifier, etc. of the second device), determines the set of management IP addresses in the corresponding regional range based on the geographic location, and selects a management IP address from the set of management IP addresses as the management IP address allocated to the first device. The third message containing the management IP address is further sent to the first device via the second device.

[0108] Specifically, the third device receives an online notification (i.e., a second message) from a newly online network element (i.e., the first device), obtains the default network element IP address (automatically generated by default) of the newly online network element, and the network element IP address of the neighboring network element (i.e., the second device). If the neighboring network element does not have the port forwarding function enabled, the third device sends a command to the neighboring network element to enable port forwarding. The third device applies for an independent available TCP port (e.g., PortL) for each newly online network element. The third device performs local configuration, establishes an SSH tunnel from the local PortL to the neighboring network element, and implements an SSH port forwarding channel from the local PortL to the newly online network element PortR (Server port 830 defined by Netconf). The third device establishes a Netconf session with the newly online network element by accessing localhost:PortL, and completes the modification of the network element IP address as planned. The third device performs local configuration, releases the used TCP port, and dismantles the SSH port forwarding channel to the newly online network element. If the third device determines that there is no SSH tunnel passing through the neighboring network element, it sends a command to the neighboring network element to disable the port forwarding function.
