technical field

Embodiments of the present disclosure relate to the communication field, and in particular, relate to a port state adjustment method, device, computer-readable storage medium, and electronic device.

Background technique

In the current network construction, in order to ensure the stability and reliability of the network and the economy of the network, the link aggregation control protocol (Link Aggregation Control Protocol, referred to as LACP) group method is often used to enhance the bandwidth. This technology can treat multiple physical connections as a single logical connection, allowing two network devices to be connected in parallel through multiple ports and transmit data at the same time to provide higher bandwidth and throughput.

Dynamic aggregation is a way to realize link aggregation. Under the interaction of the LACP protocol, information is exchanged with the peer through the link aggregation control protocol data unit (Link Aggregation Control Protocol Data Unit, referred to as LACPDU). After the negotiation between the two ends is successful, the traffic can be load-balanced among the activated member ports.

In the scenario where LACP is used, it is necessary to ensure that a large number of packets are not lost during link restoration. When the devices at both ends perform LACP protocol interaction, after the port of the peer device recovers, the data flow will be sent on this port, but at this time the port of the local device has not recovered and lost. When the recovery time difference is larger, the packet loss will be more, and the recovery performance will be worse.

However, when the network environment fluctuates, or the peer device performs abnormal protocol processing, it will mistakenly judge that the unrecovered port of the local device has been restored, and then send packets to the unrecovered port, resulting in packet loss.

For the above problems, no effective solution has been proposed yet.

In this embodiment, a port state adjustment method is provided. FIG. 2 is a flowchart of a port state adjustment method according to an embodiment of the present disclosure. As shown in FIG. 2 , the process includes the following steps:

Step S202, the first device acquires a first message from the second device, wherein the first message carries first state information, and the first state information is used to indicate the state of the first port included in the first device, The first device performs data transmission with the second device through the first port;

In this embodiment, the first status information includes (but is not limited to) activation/inactivation/abnormal status information of the first port included in the first device, address information of the first port, port type of the first port, and other information , the number of the first port can be (but not limited to) one or at least two; both the first device and the second device are (but not limited to) devices or devices that can execute the interaction of the LACP protocol, such as switches, gateways, etc.; The number of the first device and the second device can be (but not limited to) multiple, as long as the information interaction between the first device and the second device can be realized; the first message can be (but not limited to) The data packet can also be other information streams capable of various information; the data transmission method of the first message can be (but not limited to) Ethernet, etc., or a wireless network, such as 3G/4G/5G/quantum communication Wait.

For example, the first device receives the LACP packet sent by the second device, and parses the first packet to obtain port parameters in the first packet.

Step S204, the first device determines the capability information of the first port based on the first state information and the actual state of the first port read by the first device, wherein the capability information is used to indicate whether the first port is allowed to recover from the abnormal state to normal state;

In this embodiment, the actual state of the first port is the state of the first port within the time range of receiving the first message, and the time range can be the time node when the first message is received, or a specified delay time. A long time node; the actual status reading of the first port can be (but not limited to) realized by reading the status code identifying the first port, or by receiving the port status information or signal fed back by the first port The determination may also be realized by other means; the actual status of the first port includes (but not limited to) normal, abnormal, activated but not activated, inactivated, and so on.

For example, the first device reads the actual port status of the first device itself while parsing the first packet.

Step S206, if the capability information is the first capability information, the first device activates the first port so that the state of the first port changes from an abnormal state to a normal state, wherein the first capability information is used to indicate The first port is allowed to recover from the abnormal state to the normal state.

In this embodiment, the first capability information is that the first port is in an abnormal state that can be activated but not activated. By activating the first port, the normal information exchange of the first port can be realized, and the abnormal state of the port can be avoided. data loss.

Wherein, the activation process for the first port may be normal activation or forced activation, and the activation status may indicate that the first port remains activated within a predetermined time, or indicate that the first port is always in an activated state; The method can be realized by sending an activation command to the first port, or by adjusting the physical information (such as address code, current and voltage, etc.) of the first port.

For example, the first device confirms whether the first port in the LACP aggregation group between itself and the second device can recover through LACP protocol interaction and negotiation, and when the physical status of the first port itself is normal, the port may be blocked due to protocol interaction failure. Deactivated and unable to send and receive data. Therefore, if the physical state of the port of the first device is normal, but when data cannot be sent and received due to protocol interaction, a forced activation command can be sent to the first port to make it forcedly activated; wherein, the physical state of the first port can (but Not limited to) is determined by polling and scanning the first port.

Through the above steps, due to the adjustment of the port state of the first port in the abnormal state, the first port can perform data interaction normally, thereby avoiding the data packet loss phenomenon caused by the abnormal state of the port, and solving the data loss caused by the abnormal state of the port. Packet problem, improved data transmission stability.

Wherein, the execution subject of the above steps may be a base station, a terminal, etc., but is not limited thereto.

In an optional embodiment, the first device determining the first capability information of the first port based on the first state information and the actual state of the first port read by the first device includes:

In step S2042, the first device determines that the first state information is used to indicate that the state of the first port included in the first device is an abnormal state or a normal state, and the actual state of the first port read by the first device is a normal state. In some cases, it is determined that the capability information of the first port is the first capability information.

In this embodiment, since the first message is from the second device, there may be a situation where the state information of the first port lags behind, and by comparing and confirming the state information of the first port, the second device can store The state information of the first port of the device is updated, so as to prevent the second device from sending and receiving packets by mistake.

In step S2044, the first device determines that the first state information is used to indicate that the state of the first port included in the first device is an abnormal state or a normal state, the actual state of the first port read by the first device is a normal state, and In a case where the first device determines that the first port can be recovered after performing the first protocol interaction negotiation with the second device, determine the capability information of the first port as the first capability information.

In this embodiment, the purpose of determining the capability information of the first port as the first capability information after it is determined that the first port can be restored is to perform a forced activation operation on the first port, so that the first port can realize normal operation. data interaction.

In an optional embodiment, after the first device activates the first port, the method further includes:

Step S208, the first device sends a second message to the second device, wherein the second message includes second state information for indicating that the state of the first port has returned to a normal state;

Step S2010, the first device terminates sending a third message to the second device, wherein the third message includes third status information for indicating that the status of the first port is an abnormal status.

In this embodiment, the purpose of sending the second message to the second device is to enable the second device to update the stored state information of the first port, and the purpose of stopping sending the third message is to prevent the second device from Messages send feedback messages to avoid data loss.

Wherein, both the second message and the third message may include (but not limited to) information such as status information and an IP address of the first port, and the first port indicated by the third message may be the first port included in the first device. One or more of the multiple first ports, similarly, the first port indicated by the second message may be one or more of the multiple first ports contained in the first device; the second message The method of sending the third message may be (but not limited to) Ethernet, or wireless network, such as 3G/4G/5G/quantum communication.

For example, when entering the fast recovery processing flow (that is, the forced activation process), the first device needs to directly restore (that is, forcibly activate) the port that has not been restored, and at the same time, the first device sends a message that the first port has been restored to the second device. LACP protocol packets. At the same time, it is necessary to intercept the LACP protocol message whose port status has not been restored and which the first device is about to send.

Step S2012, the first device performs a second protocol interaction negotiation with the second device through the first port;

Step S2014, when the first device determines that it cannot successfully negotiate with the second device based on the second protocol interaction negotiation process, it performs a first deactivation process on the first port, so that the state of the first port changes from a normal state to an abnormal state state.

In this embodiment, after the activation process is performed, it is determined whether the first port is recovered through interactive negotiation, and then subsequent data interaction is performed, so as to avoid data loss caused by the unrecovered port status; The purpose of port deactivation is to avoid data interaction with abnormal ports and further avoid data loss.

Wherein, the second protocol may be (but not limited to) the LACP protocol, or other interactive protocols; the deactivation process may be (but not limited to) adjusting the state of the first port, or making the first port Identified as abnormal; the way of deactivation processing may be sending a deactivation command to the first port, or changing the physical information of the first port, etc.

For example, if it is confirmed according to the subsequent LACP protocol interaction that the LACP protocol negotiation of the fast-recovery port fails, the status is rolled back, and the fast-recovery port of the first device is deactivated from the aggregated link.

In an optional embodiment, after the first device deactivates the first port, the method further includes:

Step S2016, the first device sends a fourth message to the second device to instruct the second device to perform a second deactivation process on the second port connected to the first port included in the second device, wherein, in the fourth message It includes fourth state information for indicating that the state of the first port is an abnormal state.

In this embodiment, when it is determined that the first port cannot be recovered, the second port is also made to perform the second deactivation process, so as to prevent the second port from sending data to the first port. In addition, it should be noted that the information sent in different states to indicate that the state of the first port is an abnormal state may be the same information or different information. For this embodiment, the fourth state information Both the aforementioned third status information and the aforementioned third status information are used to indicate that the status of the first port is an abnormal status, and the two may be the same information or different information.

For example, an LACP protocol packet for port deactivation is sent to the second device, so as to notify the second device to perform deactivation processing on the docking port of the second device.

Step S2018, the first device sends an alarm message.

In this embodiment, the purpose of sending the alarm information is to remind the staff to perform further processing on the relevant ports, so as to adjust the ports in time.

For example, the abnormal state of the first device port that cannot be recovered is sent through an alarm or other means, and relevant personnel are notified to perform troubleshooting.

In an optional embodiment, after the first device acquires the first packet from the second device, the method further includes:

Step S2022, the first device replies a fifth message to the second device based on the first message, wherein the fifth message carries fifth state information, and the fifth state information is used to instruct the first device to The obtained state of the first port;

Step S2024, the first device acquires fifth state information, and compares the first state information with the fifth state information to obtain a comparison result;

Step S2026, when the first device determines that the comparison result indicates that the states indicated by the first state information and the fifth state information are different, stop replying the fifth message to the second device.

In this embodiment, in order to improve the ability to interact with data, a first device and a second device having the same function of sending and receiving data may be set.

For example, after the first device receives the fifth message sent by the second device, it parses the fifth message to determine the fifth status information, and at the same time sends reply information to the second device through the control system in the first device , and before the reply information is sent, the first device captures and analyzes the reply that has been generated but not sent, and determines whether the fifth state information is consistent with the actual state of the first port read by the first device. The reply message is intercepted; correspondingly, after the second device receives the fifth message sent by the first device, the control system of the second device also generates a reply message, and before sending the reply message The fifth state information is compared with the pre-stored first state information, and if they are inconsistent, the reply is intercepted.

In an optional embodiment, after the first device terminates restoring the fifth message to the second device, the method further includes:

Step S20262, the first device sends a notification message to the second device, wherein the notification message is used to notify the second device to resend the packet.

In this embodiment, the purpose of resending the message is to ensure the consistency of the port status, realize normal data interaction, and avoid data loss.

It should be noted that, when the second device confirms that the reply message is wrong, it may also send a notification message to the first device, so as to instruct the first device to resend the message.

Step S20264, the first device constructs and sends a sixth message, wherein the sixth message carries sixth state information, and the sixth state information is used to indicate the state indicated by the first state information.

In this embodiment, the purpose of reconstructing the sixth packet is to update the port status information stored in the second device and ensure consistency of the port status.

It should be noted that when the second device confirms that the reply message is wrong, it may also reconstruct the sixth message, so as to notify the first device that the first port status information stored in the second device has been updated.

The present disclosure will be described below in conjunction with specific embodiments.

As shown in FIG. 4 , a network environment is provided, in which two devices interact through aggregated links.

Wherein, the LACP protocol message based on the IEEE802.3ad standard stores the port states of the local device and the peer device respectively. Usually, the status of the device port can read the status of the sending port in the received message. And in the subsequent protocol message reply, fill in the own port status and the read port status in the message and send it. However, due to network reasons or its own protocol processing problems, the status of the peer read in the reply message may be wrong. In view of this situation, the data transmission method of the present application can solve this problem.

It should be noted that the first device and the second device in this application are mainly used to distinguish similar objects. The second device may wrongly judge the port status of the first device. For example, in the packet sent by the first device, the port status is 0x05, which means that the port of the first device cannot be restored currently. However, after the second device receives the message, the port status of the first device in the reply message is 0x0d, indicating that the port of the first device can be aggregated, that is, can be restored. This is due to an error in the state of the port, causing the second port to send the data stream to the wrongly judged first device port, thus causing packet loss. Data exchange can be performed normally only after the first device port is actually recovered.

As shown in Figure 5, corresponding to the above-mentioned network environment and protocol message sending and receiving, this embodiment provides a data transmission system, which is used in the aforementioned first device, including:

A packet sending and receiving module 51, which is mainly responsible for receiving and sending LACP protocol packets. After the LACP protocol message is sent from the second device, the module can be responsible for receiving the message and handing the message information to the protocol module of the first device for analysis. In addition, when the first device needs to perform fast recovery processing, it can send the LACP protocol message for port recovery, and intercept the LACP protocol message for port recovery sent by the first device.

A protocol module 52, which is mainly responsible for parsing LACP protocol messages, recording port states in the messages and comparing port state differences. If the first device needs to perform fast port recovery processing, the protocol module is also responsible for constructing an LACP protocol message, and handing it over to the sending and receiving packet module to send to the second device. In addition, the protocol module is also responsible for judging whether the port undergoing fast recovery processing on the first device needs state rollback, that is, to deactivate the fast recovered port from the aggregated link, and re-interact with the LACP protocol to determine the port status.

Port module 53, this module is mainly responsible for reading the actual port status of the first device's ready to restore port when necessary, and handing the read port status to the protocol module, the actual status and the second device sent by the protocol module The port status of the first device in the LACP message is compared and processed. In addition, the module notifies the port to perform fast recovery during fast recovery processing or notifies the port to deactivate when state rollback is required.

Alarm module 54, this module is mainly responsible for sending relevant alarms to colleagues who perform state rollback port deactivation when the port of the first device is quickly restored and found that the port cannot be negotiated successfully through subsequent LACP protocol interaction. Notify the staff to troubleshoot in time.

Correspondingly, as shown in FIG. 6, the data transmission method of this embodiment includes the following steps:

In step S61 (corresponding to the aforementioned step S202), the first device receives the LACP message sent by the second device, and parses the port parameters in the message. And read the actual port status of the first device itself.

Step S62 (corresponding to the aforementioned steps S204 and S206), comparing the port status of the first device in the message sent by the second device with the actual port status of the first device. If it is found that the port of the first device in the message can be restored, but in fact the port has not been restored, it will enter the fast recovery process; in other cases, do not do any processing, and continue to interact with the LACP protocol.

It should be noted that, the ports in the LACP aggregation group in the first device and the second device confirm whether they can recover through LACP protocol interaction and negotiation. When the physical state of the port itself is normal, the port may be deactivated due to protocol interaction failure and cannot send and receive data. Therefore, in the above step S62, if the physical state of the port of the first device is normal, but the data cannot be sent and received due to protocol interaction, it can be activated forcibly. This situation is exactly the method for fast recovery of ports mentioned in this patent.

In step S63 (corresponding to the aforementioned steps S208 and S2010), when entering the fast recovery process flow, the first device needs to directly recover the port that has not been recovered, and at the same time, the first device sends the LACP protocol message of the port that has been recovered. At the same time, it is necessary to intercept the LACP protocol message whose port status has not been restored and which the first device is about to send.

In step S64 (corresponding to the aforementioned steps S2012, S2014, and S2016), the LACP protocol interaction is continued after the first device port has recovered. If the port of the first device can indeed be recovered, it is maintained; if it is found through subsequent LACP protocol interaction that the LACP protocol of the port that is recovering quickly cannot be successfully negotiated, the state is rolled back. That is, the port on which the first device quickly recovers is deactivated from the aggregated link, and sends a port deactivation LACP protocol packet to notify the second device to deactivate the interconnected port.

In step S65 (corresponding to the aforementioned step S2018), if the fallback in step S64 occurs, it is necessary to send the abnormal state that the first device port cannot recover by means of an alarm, etc., and notify relevant personnel to perform troubleshooting.

As shown in Figure 7, in order to prevent the second device from misjudging the port status of the first device, thereby preventing the second device from sending data to the unrecovered port of the first device and causing packet loss, and improving recovery performance, in another specific embodiment, Include the following steps:

In step S71, the second device receives the LACP protocol message sent by the first device, parses and records the port status of the first device in the message.

Step S72, after the second device receives the message, the system replies with the LACP protocol message after protocol processing, and at this time analyzes the replied protocol message, and records the port status of the first device in the reply message.

Step S73, comparing the port status in the received message and the reply message, if it is found that the second device mistakenly identifies the port status of the first device, that is, the port status of the first device in the received message is not consistent with the sent message, then The wrong LACP protocol message replied by the second device is intercepted, and at the same time, the second device is notified to perform protocol interaction again.

Step S74: After intercepting the wrong LACP protocol message, in order to improve the interaction efficiency, the LACP protocol message with the correct port status can be constructed and sent to the first device without waiting for the result of the second device's re-protocol interaction.

Correspondingly, as shown in Figure 8, the system applied to the aforementioned second device includes:

A packet sending and receiving module 81, which is mainly responsible for receiving and sending LACP protocol packets. After the LACP protocol is sent from the first device, the module can be responsible for receiving the message. In addition, when it is found that the port states in the above messages are inconsistent, the port recovery protocol message can be sent instead of the second system, and the wrong port state protocol message sent by the second system can be intercepted.

A protocol module 82, which is mainly responsible for parsing LACP protocol port messages and comparing port states. If it is found that the port state in the message is inconsistent, the second system is notified to perform protocol interaction again, and a protocol message with the correct port state is constructed and sent to the sending and receiving packet module.
