Description
Technical Field
Embodiments of the present disclosure relate generally to the field of the internet and, more particularly, to a data communication method, system, device and computer-readable storage medium of a network node.
Background
Currently, in an SDN (Software Defined Network) wide area Network communication Network, if Network functions of transmission nodes constituting the Network need to be upgraded, a specific image file (group) needs to be imported into a Network node management platform (SDN Controller) and an image file management service is started, and an archive file such as star, gz or qcow2 is distributed to each Network node through the service process.
The network node management and control platform executes a group of configuration commands on the network node to activate the distributed archive and install the image file. Network nodes typically automatically reboot after installing the image to initialize the system and load the installed image file. The network node management and control platform actively starts to poll the network node at a preset time (for example, after 3 minutes) after the mirror image installation process of the network node is activated, for example, using a PING command to detect whether the network node has a response.
Once the network node completes the reboot and responds to the PING command from the network node management platform, the network node management platform issues a more specific Command Line Interface (CLI) command to the network communication nodes to determine the upgraded state.
The scheme for upgrading the network function of the node by using the mirror image file has the following problems:
firstly, the network nodes may need a relatively long time to restart after the mirror image is installed, which requires a manager to repeatedly test the restart speed and synchronization time of different types of network nodes when different mirror image versions are loaded, so that the network node management and control platform can initiate polling test at a relatively proper time, which greatly affects the availability of the network.
Second, since network nodes may exist in various local area network environments, their underlying network connections may be local area network gateway devices using Dynamic Host Configuration Protocol (DHCP) services to dynamically assign traffic IP addresses. The DHCP service does not enforce that the service IP address assigned to the same host at each time is completely consistent with that previously assigned, and the service IP address obtained by the network communication node from the local lan gateway device after the restart may not be consistent with that previously assigned. In this case, when the network node management and control platform polls the old traffic IP address of the network node, an error is generated.
In addition, opening a port on the upgraded network node to listen for later live polling by the network node management and control platform may create a potential security breach.
Finally, a firewall may be deployed between the network node and the network node management and control platform. The change of the service IP address and the interruption of the session may cause the network node management and control platform to fail to access the node after the network node is restarted.

Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are some, but not all embodiments of the present disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
In the disclosure, after the network node to be upgraded performs network upgrade by using the received image network upgrade file, the network node to be upgraded is actively returned to the network node control platform, so that the situation that a manager needs to repeatedly test the restart speed and the synchronization time of different types of network nodes when different image versions are loaded to determine a proper polling time due to the fact that the network node control platform needs to poll the network nodes can be avoided; and the connection back to the network node control platform can also improve the communication efficiency between the network node control platform and the network node to be upgraded, and avoid resource consumption caused by polling.
Fig. 1 shows a flow chart of a method 100 of data communication of a network node according to an embodiment of the present disclosure. As shown in fig. 1, the method 100 may include:
The network node management and control platform is used for managing and controlling the network node to be upgraded, and may be located in the same network or a different network from the network node to be upgraded, which is not limited in this disclosure.
the image network upgrading file is used for upgrading the network functions of the network node to be upgraded, such as a wifi module.
And 140, performing data communication between the network node to be upgraded and the network node management and control platform through the first communication link.
After the network node to be upgraded is upgraded by using the received image network upgrade file, the network node to be upgraded can actively return to the network node control platform, so that the situation that a manager needs to repeatedly test the restart speed and the synchronization time of different types of network nodes when different image versions are loaded to determine a proper polling time due to the fact that the network node control platform needs to poll the network nodes can be avoided; and the connection back to the network node control platform can also improve the communication efficiency between the network node control platform and the network node to be upgraded, and avoid resource consumption caused by polling.
In addition, no matter what the type of the network node to be upgraded and the version of the image network upgrade file are, the network node to be upgraded can actively return to the network node control platform when the network upgrade is completed, so that the potential security loophole caused by opening a port on the upgraded network node for monitoring can be avoided; furthermore, it can be avoided that the network node management and control platform cannot access the network node after the network node is restarted due to the change of the service IP address of the network node to be upgraded because a firewall may be deployed between the network node and the network node management and control platform.
In one embodiment, when the network node to be upgraded is completed, actively establishing a first communication link with the network node management and control platform, including:
when the network node to be upgraded finishes network upgrading, actively sending a first connection request to the network node control platform through a service IP address of the network node to be upgraded; the first connection request carries an identifier of the network node to be upgraded; the identifier includes, but is not limited to, a service IP address, a number, a name, etc. of the network node to be upgraded, for example, the identifier may include the number of machines of the XX local area network in addition to the service IP address.
The traffic IP address may be an IP address dynamically assigned by the network node local area network gateway device to be upgraded using a Dynamic Host Configuration Protocol (DHCP) service. The service IP address is used for daily communication between the network node to be upgraded and the network node control platform.
And after receiving the first connection request, the network node management and control platform establishes the first communication link with the network node to be upgraded.
When the network node to be upgraded is upgraded, the network node to be upgraded can actively send the first connection request to the network node control platform through the service IP address of the network node to be upgraded, so that the network node control platform establishes the first communication link with the network node to be upgraded after receiving the first connection request, and the network node to be upgraded can be quickly connected back.
And the network node to be upgraded is actively connected back, so that even if the service IP address of the network node to be upgraded changes before and after the network node to be upgraded is upgraded, communication errors caused by polling of the old service IP address by the network node management and control platform can be avoided.
In an embodiment, if the network node management and control platform does not establish the first communication link with the network node to be upgraded within a preset time period, the network node management and control platform sends a second connection request to a fixed management IP address of the network node to be upgraded, so as to establish a second communication link with the network node to be upgraded.
The fixed management IP address may be maintained by a Virtual Network Function (VNF), such as by manual configuration of the management IP address by the VNF.
The second communication link and the first communication link use different network modules on the network node to be upgraded, if the first communication link uses a wifi module, the second communication link uses a 5G SIM card module or a 4G SIM card module, and the second communication link is not necessarily enabled due to various limitations of bandwidth, charging and the like, so that network resources on the network node to be upgraded are reasonably used.
If the network node management and control platform does not establish the first communication link with the network node to be upgraded within the preset time length, the network node to be upgraded may not successfully utilize the mirror image network upgrade file to complete the upgrade of the network function, so that the fixed management IP address of the network node to be upgraded can be utilized to send a second connection request to the fixed management IP address of the network node to be upgraded so as to establish a second communication link with the network node to be upgraded, and even if the network node to be upgraded does not complete the upgrade of the network function, the network node management and control platform and the network node to be upgraded are not disconnected, and normal communication can be maintained.
In addition, since the service IP address is dynamically allocated to the network node to be upgraded by the lan gateway device using a Dynamic Host Configuration Protocol (DHCP) service, the service IP address may be dynamically changed, so that the network node to be upgraded maintains a fixed management IP address, when the network node to be upgraded cannot communicate with the network node management and control platform using the service IP address due to a network upgrade failure, the network node management and control platform can still normally communicate with the network node to be upgraded through the management IP address of the network node to be upgraded, and a communication failure between the network node management and control platform and the network node to be upgraded due to a change in the service IP address is avoided.
In one embodiment, the method further comprises:
the network node management and control platform sends a control instruction to the network node to be upgraded through the second communication link, wherein:
the control instructions include at least one of:
a state rollback instruction, a node restart instruction and a reinstallation instruction of the image network upgrade file.
After the network node management and control platform cannot establish the first communication link with the network node to be upgraded, the network node management and control platform can automatically send a control instruction to the network node to be upgraded through the established second communication link so as to control the network node to be upgraded, for example, control the network node to be upgraded to perform state rollback, restart the network node to be upgraded or control the network node to be upgraded to reinstall the image network upgrade file.
The state rollback instruction is used for controlling the network node to be upgraded to roll back to the network state corresponding to the image network upgrading file before updating.
In an embodiment, the network node management and control platform determines the preset duration according to an upgrade requirement corresponding to the image network upgrade file.
The network node management and control platform can automatically determine accurate preset time according to the specific corresponding upgrading requirement of the image network upgrading file, for example: if the upgrade requirement is to upgrade a part of files in the image network upgrade files, the preset time is short, and if the upgrade requirement is to upgrade the whole image network files, the preset time is long.
In one embodiment, the network node management and control platform sends an upgrade inquiry request to the network node to be upgraded based on the first communication link or the second communication link;
after receiving the upgrading query request, the network node to be upgraded returns a mirror image upgrading result to the network node management and control platform;
the image upgrade result comprises at least one of:
whether to utilize the image network upgrading file to complete network upgrading, network upgrading progress, network upgrading time consumption, network upgrading resource consumption and starting conditions of the network node to be upgraded.
The network node management and control platform can automatically send an upgrading query request to the network node to be upgraded by utilizing the first communication link or the second communication link, so that a mirror image upgrading result of the network node to be upgraded is obtained, and the upgrading state of the network node to be upgraded can be timely confirmed.
Of course, since the second communication link is established only when the first communication link cannot be established (i.e. the network node to be upgraded cannot successfully complete the network function upgrade using the image network upgrade file), the contents to be queried of the upgrade query request sent through the first communication link and the upgrade query request sent through the second communication link are different, for example: if the upgrade query request can be sent through the first communication link, the network upgrade is finished, so that whether the network upgrade and the network upgrade progress are finished by using the image network upgrade file is not required to be inquired, and the upgrade query request is sent through the second communication link, whether the network upgrade and the network upgrade progress are finished by using the image network upgrade file is required to be inquired, so that whether the network node to be upgraded cannot be successfully connected back or not due to the fact that the network upgrade cannot be finished by using the image network upgrade file successfully is determined.
In one embodiment, the first communication link or the second communication link is an encrypted network tunnel based on a TCP connection;
the network node to be upgraded and the network node management and control platform perform data communication through the first communication link, and the method includes:
on the first communication link, the network node to be upgraded reports target information to the network node management and control platform in an RPC mode, wherein the target information comprises: the network state of the network node to be upgraded and the resource use condition of the network node to be upgraded.
No matter the first communication link or the second communication link between the network node to be upgraded and the network node control platform can be an encrypted network tunnel based on TCP connection, that is, the TCP network link between the network node to be upgraded and the network node control platform can be established on the encrypted network protocol based on Secure Shell (SSH), so as to ensure further system security.
Certainly, on the first communication link, the network node to be upgraded may report the target information to the network node management and control platform in an RPC (Remote Procedure Call) manner, so that the network node management and control platform may timely know the current state of the network node to be upgraded, such as resource consumption condition, whether the network state is good, and so on, thereby timely scheduling and reasonably allocating resources and optimizing the network environment.
It is noted that while for simplicity of explanation, the foregoing method embodiments have been described as a series of acts or combination of acts, it will be appreciated by those skilled in the art that the present disclosure is not limited by the order of acts, as some steps may, in accordance with the present disclosure, occur in other orders and concurrently.

installing and loading an independent microkernel on a controlled wide area network node to monitor the real-time state of the node and monitor and issue a control instruction;
installing or upgrading new function module software on a wide area network node, namely restarting the node after finishing network upgrading by using a mirror image network upgrading file;
furthermore, the wide area network node actively initiates a TCP connection request to the network node management by the client identity so as to actively connect back with the network node management platform;
on the encryption network tunnel, a network node management and control platform manages the network node in an RPC (Remote Procedure Call) mode through a NETCONF network management protocol, and sends various control instructions and the like;
