Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method, device, equipment and medium for preventing switch mirror back pressure. Background Art

[0002] Network monitoring and troubleshooting are important components of network operation and maintenance, and port mirroring plays an important role in this process. Without affecting the normal message forwarding function, users can use the port mirroring function to mirror the messages and data flows of the specified source port to the specified mirror destination port; this port is usually connected to a network monitoring device to monitor the ingress and egress of a specific port or a specific flow and monitor traffic, thereby providing assistance and reference for monitoring the operation status of network equipment, locating faults, and guiding troubleshooting.

[0003] However, in practice, the mirroring port itself may also become a point of failure, such as mirroring back pressure. When the mirroring destination port message is continuously congested, the buffer of the chip where the mirroring source port is located is full of back pressure, causing the chip's inbound / outbound service message and protocol message forwarding packet loss, which in turn leads to a large number of low-priority BPDU messages, buffer fullness, MAC address drift and other problems, which will make the network equipment unable to provide network services normally, causing service interruption.

[0004] The existing preventive disposal solutions for the technical solutions of mirror back pressure of control switches are usually: detect the port mirror destination port, and when its bandwidth utilization is greater than 90%, delete the port mirror configuration in advance. This solution is designed based on the fact that the traffic of the mirror destination port is twice the inbound / outbound traffic of the mirror source port, so that the mirror source port where the mirror back pressure fault actually occurs can be indirectly detected and preventively deleted. However, there are also objective shortcomings. First of all, the preventive measures need to be optimized: 1. It only treats the symptoms but not the root cause, and can only be monitored passively, not actively improved; 2. Port mirroring itself is used for network monitoring. Each mirror destination port used for monitoring is monitored again. On the one hand, the number of indicators that the network monitoring system needs to pay attention to is directly doubled, increasing the monitoring pressure. On the other hand, this also increases the non-business traffic of the device again, increases the traffic pressure and CPU load of the device, and further reduces the business support ability of the device that may have bottlenecks in related parameters; 3. The port mirroring configuration needs to be deleted every time the bandwidth utilization rate of the port mirroring destination port exceeds 90%. There are also negative effects. First, this operation will make the corresponding mirroring source port traffic unable to be detected normally, making the network monitoring partially ineffective and increasing the overall network security risk; secondly, this operation It is not possible to automate the operation and maintenance, which will consume a lot of change windows and work energy of the operation and maintenance personnel; finally, this operation cannot solve the problem or reduce the frequency of subsequent problems. A port mirroring configuration that has experienced a port mirroring destination port bandwidth utilization rate of more than 90% is likely to have problems repeatedly and fall into a cycle of alarm-deletion-reconfiguration-alarm; 4. In actual work, the rise and fall of business traffic is not necessarily a smooth change. From the time point when the port mirroring destination port bandwidth utilization rate exceeds 90% to the time point when the port mirroring source port bandwidth utilization rate exceeds 50% and triggers port mirroring back pressure, there may not be enough response time for handling. Even during some sudden business peaks, it cannot be ruled out that the former is directly skipped and the latter occurs; at this time, the preventive disposal plan cannot be responded to and implemented in time, the preventive disposal fails, and the emergency disposal stage must be entered.

[0005] In the existing technical solutions for dealing with the mirror back pressure of the control switch, the emergency disposal solutions are usually:

[0006] 1. Check and confirm the status of all port mirroring source ports and port mirroring destination ports on the device, and delete all port mirroring configurations that cause port mirroring back pressure. Example command: undo mirroring-group X;

[0007] 2. Reboot the device to release the board buffer resources. Example command: reboot chassis X;

[0008] Based on the above, we can know that under the premise that the current preventive disposal scheme only treats the symptoms but not the root cause, is complicated to deal with, and may not be suitable for the actual problem situation of business traffic, the emergency disposal scheme will be activated at a relatively high frequency. However, the first emergency disposal scheme of simply deleting the port mirroring configuration cannot solve the problem immediately, because it takes a certain amount of time to release the buffer resources after deletion, which does not conform to the emergency disposal principle of giving priority to rapid recovery of business; the second emergency disposal scheme will directly affect the normal operation of the business, and this impact is relatively significant. Summary of the invention

[0050] The emergency response plan is activated at a relatively high frequency, given that the existing preventive measures for switch mirror back pressure are only symptomatic and complicated, and may not be suitable for the actual problem scenarios of business traffic. However, the emergency response plan in the existing preventive measures for switch mirror back pressure is to simply delete the port mirror configuration, which cannot solve the problem immediately, because it takes a certain amount of time to release the buffer resources after deletion, which does not conform to the emergency response principle of giving priority to rapid business recovery; the second emergency response plan will directly affect the normal operation of the business, and this impact is relatively significant.

[0051] Based on this, the embodiments of the present application provide a method, device, equipment and medium for preventing switch mirror back pressure, which are described below through embodiments.

[0052] Example 1

[0053] To facilitate understanding of this embodiment, a method for verifying real participation in an activity disclosed in an embodiment of this application is first described in detail. Figure 1 A flowchart of a method for verifying real participation in an activity is shown in the figure. A method for preventing mirror back pressure of a switch provided in the present application is applicable to a prevention system, wherein the prevention system includes a service destination port of the switch, a mirror destination port, a network board, a network chip for receiving multicast messages, and a network chip for sending multicast messages. The method includes:

[0054] S101, the switch receives a message sent by an external device to obtain a multicast message, and controls the multicast message to process the data packet and transmit it to the network chip receiving the multicast message through the target multicast structure in the message; the switch is configured based on the multicast communication mechanism;

[0055] S102, the network chip receiving the multicast message obtains a multicast message unit set based on the received multicast message, and sends the multicast message unit set to the network board; the multicast message unit set includes a plurality of multicast message units;

[0056] S103, the network board receives the multicast message unit set, and forwards the multicast message unit set to a network chip that sends a multicast message, so that the network chip that sends the multicast message reassembles a plurality of multicast message units in the received multicast message unit set to obtain a reassembled multicast message; the network chip that sends the multicast message corresponds to the multicast communication mechanism;

[0057] S104, the network chip sending the multicast message sends the reassembled multicast message to the service destination port and the mirror destination port in the switch via the target multicast structure, so that the service destination port and the mirror destination port can respectively normally receive the message sent by the external device.

[0058] In step S101, the switch receives a message sent by an external device and obtains a multicast message, wherein the external device is an external device that forwards the message through the switch, which may be a terminal, a personal computer, etc. The switch is used to forward the message sent by the terminal or the personal computer to a server or a host computer, etc. The message includes a data request and key information such as a target multicast structure, data content, a source address, and a destination address. The target multicast structure is set by the switch through a multicast communication mechanism, which may be a multicast queue or other. After the message is received by the switch configured based on the multicast communication mechanism, the switch determines that the message is a multicast message based on the target multicast structure. After the switch controls the multicast message to perform a packet processing, i.e., a PP (Packet Processing) process, the message enters a target multicast structure, i.e., a multicast queue, in the switch corresponding to the target multicast structure in the message. The target multicast structure transmits the multicast message to a network chip that receives the multicast message.

[0059] The switch is configured based on the multicast communication mechanism, that is, the service destination port and the mirror destination port on the switch are configured with the multicast communication mechanism. Therefore, the switch of the present application can realize the transmission of the message through the multicast communication mechanism.

[0060] In the specific implementation process of step S101, there is an embodiment in which the switch receives a message sent by an external device to obtain a multicast message, and controls the multicast message to perform data packet processing and transmit it to a network chip that receives the multicast message through a target multicast structure in the message, including:

[0061] S1011, the switch generates a target multicast structure corresponding to the multicast communication mechanism after being configured according to the multicast communication mechanism;

[0062] S1012. The switch transmits the multicast message after data packet processing to the network chip that receives the multicast message through the target multicast structure.

[0063] In steps S1011-S1012, the switch generates multiple multicast structures of the multicast communication mechanism after being configured according to the multicast communication mechanism. After receiving a message including a target multicast structure, the switch parses the message and further parses the multicast address corresponding to the target multicast structure in the message to determine the multicast structure in the switch corresponding to the target multicast result in the message, i.e., the multicast queue, and uses this multicast queue as the target multicast queue. After determining the target multicast structure of the target multicast queue, the switch transmits the multicast message that has undergone data packet processing to a network chip that receives the multicast message under the command of the target multicast structure including the multicast queue. The network chip that receives the multicast message is specified by the multicast communication mechanism, and the model of the network chip that receives the multicast message is not limited herein.

[0064] In step S102, the network chip that receives the multicast message is a network chip that receives and decomposes the multicast message. After receiving the multicast message based on the target multicast queue, the network chip that receives the multicast message processes the multicast message to obtain multiple multicast message units. The multiple multicast message units respectively store relevant information or key information of the multicast message. Therefore, the multiple multicast messages are processed again to obtain a multicast message unit set. The multicast message unit set represents the data content of all relevant multicast messages received by the network chip, and the multicast message unit set is determined according to the target multicast structure in the multicast message, that is, the target multicast queue, to the network board to which the multicast message unit set needs to be sent, that is, the network board is determined by the target multicast structure, that is, the target multicast queue.

[0065] In the specific implementation process of step S102, there is an embodiment: Figure 2 As shown, the network chip receiving the multicast message obtains a multicast message unit set based on the received multicast message, including:

[0066] S1021. The network chip receiving the multicast message decomposes the received multicast message based on a preset decomposition method to obtain a plurality of multicast message units.

[0067] S1022. The network chip receiving the multicast message collects and organizes the obtained multiple multicast message units to obtain a multicast message unit set.

[0068] In steps S1021-S1022, after receiving the multicast message transmitted under the command of the target multicast queue, the network chip that receives the multicast message calls a pre-stored decomposition method, and decomposes the received multicast message based on the preset decomposition method to obtain multiple multicast message units to meet the requirements of the network board, and collects and organizes the multiple multicast message units obtained by decomposition to obtain a multicast message unit set. Therefore, there are multiple multicast message units in the multicast message unit set, that is, the multiple multicast message units obtained by decomposition are collected and organized into the multicast message unit set, avoiding the loss of multicast message units, thereby ensuring the integrity of the content in the multicast message.

[0069] In step S103, the network board receives the multicast message unit set sent by the network chip that receives the message. Since there are multiple network chips that send multicast messages corresponding to the target multicast queue, the multicast message unit set needs to be forwarded to the network chips that send multicast messages respectively, so that the network chips that send multicast messages can all receive the multicast message unit set. After receiving the multicast message unit set, the network chip that sends the multicast message reassembles the received multiple multicast message units in the multicast message unit set to obtain a reassembled multicast message; that is, the reassembled multicast message is the message sent by the external device or the longitudinal wave message generated by the switch, and the network chip that sends the multicast message corresponds to the multicast communication mechanism; thereby, the transmission of the multicast message in the switch is based on the multicast communication mechanism, so as to avoid the service destination port and the mirror destination port being unable to receive the multicast message normally.

[0070] In the specific implementation process of step S103, there is an embodiment in which the network board receives the multicast message unit set and forwards the multicast message unit set to the network chip that sends the multicast message, including:

[0071] S1031, the network board copies the received multicast message unit set to obtain multiple multicast message unit sets;

[0072] S1032: The network board sends the copied multiple multicast message unit sets to the network chip for sending multicast messages corresponding to the multicast communication mechanism.

[0073] In steps S1031-S1032, the network board copies the received multicast message unit set to obtain multiple multicast message unit sets, and the number of the multiple multicast message unit sets obtained by copying is determined according to the number of network chips for sending multicast messages corresponding to the multicast communication mechanism, that is, the number of multicast message unit sets is as large as the number of network chips for sending multicast messages corresponding to the multicast communication mechanism, that is, the network board achieves the effect of allocating the multicast message unit set to the network chip for sending multicast messages. After the network board copies the received multicast message unit set to obtain multiple multicast message unit sets, the multiple copied multicast message unit sets are respectively sent to the network chips for sending multicast messages corresponding to the multicast communication mechanism.

[0074] In step S104, after receiving the multicast message unit set sent by the network board, each network chip that sends the multicast message reassembles multiple multicast message units in the multicast message unit set to obtain a reassembled multicast message, and the reassembled multicast message is consistent with the multicast message or the message sent by the external device, that is, the reassembled multicast message has the same content as the multicast message or the message sent by the external device, so as to restore the original multicast message, and send the reassembled multicast message to the service destination port and the mirror destination port in the switch through the target multicast structure, that is, send according to the number of the service destination ports and the mirror destination ports in the switch, so that the service destination port and the mirror destination port can respectively receive the message sent by the external device normally, thereby avoiding the problem of mirror back pressure.

[0075] In the specific implementation process of step S104, there is an embodiment: Figure 3 As shown, the network chip sending the multicast message reassembles the received multiple multicast message units in the multicast message unit set to obtain a reassembled multicast message, including:

[0076] S10411, the network chip sending the multicast message calls a preset reassembly method after receiving the multicast message unit set;

[0077] S10412: The network chip sending the multicast message reassembles the multiple multicast message units in the multicast message unit set based on a preset reassembly method to obtain a reassembled multicast message corresponding to the multicast message.

[0078] In steps S10411-S10412, the network chip that sends the multicast message calls a preset reassembly method after receiving the multicast message unit set. The preset reassembly method has a corresponding relationship with the preset decomposition method in the network chip that receives the multicast message, so that the reassembled multicast message is consistent with or the same as the multicast message. When it is determined that the called reassembly method corresponds to the preset decomposition method in the network chip that receives the multicast message, the network chip that sends the multicast message reassembles the multiple multicast message units in the multicast message unit set based on the preset reassembly method to obtain a reassembled multicast message corresponding to the multicast message, thereby ensuring that the obtained reassembled multicast message is consistent with or the same as the multicast message.

[0079] In the specific implementation process of step S104, there is another embodiment in which the network chip sending the multicast message sends the reassembled multicast message to the service destination port and the mirror destination port in the switch via the target multicast structure, including:

[0080] S10421. The network chip sending the multicast message copies the reassembled multicast message to obtain multiple groups of the reassembled multicast messages.

[0081] S10422. The network chip sending the multicast message sends the multiple groups of the reassembled multicast messages to the service destination port and the mirror destination port respectively via the target multicast structure.

[0082] In steps S10421-S10422, the network chip that sends the multicast message is a network chip in the switch that implements sending the reassembled multicast message to the service destination port and the mirror destination port. The network chip that sends the multicast message copies the reassembled multicast message to obtain multiple groups of the reassembled multicast messages. The number of groups of the reassembled multicast messages corresponds to the number of the service destination ports and the mirror destination ports, that is, each of the service destination port and the mirror destination port can receive a group of reassembled multicast messages. The network chip that sends the multicast message sends the multiple groups of the reassembled multicast messages to the service destination port and the mirror destination port specified in the reassembled multicast message via the target multicast structure, so that the service destination port and the mirror destination port can receive the multicast message normally, avoiding the problem of congestion.

[0083] In the specific implementation process of step S10422, there is an embodiment in which the network chip sending the multicast message sends the plurality of groups of the reassembled multicast messages to the service destination port and the mirror destination port respectively via the target multicast structure, including:

[0084] S104221. After obtaining a plurality of groups of reassembled multicast messages, the network chip sending the multicast message calls the target multicast structure in the switch;

[0085] S104222. The network chip sending the multicast message sends it to the service destination port and the mirror destination port respectively via the target multicast structure.

[0086] In steps S104221-S104222, after the network chip that sends the multicast message obtains multiple groups of reassembled multicast messages, it will call the target multicast structure in the switch, i.e., the target multicast queue, to ensure that the message can be accurately forwarded to all intended recipients. The target multicast structure, i.e., the target multicast queue, is used to guide all necessary information for message forwarding, such as the member list of the multicast group, the forwarding path, etc. Under the guidance of the target multicast structure, the network chip that sends the multicast message will forward the reassembled multicast message to the service destination port and the mirror destination port, thereby significantly improving the transmission efficiency of the reassembled multicast message.

[0087] Example 2

[0088] The present application also provides a verification device for real participation in activities, such as Figure 4 The block diagram of a switch mirror back pressure prevention device is shown. The functions implemented by the switch mirror back pressure prevention device correspond to the steps of executing a switch mirror back pressure prevention method on the terminal device. The device can be understood as a component of a server including a processor, which is suitable for a prevention system. The prevention system includes a service destination port of the switch, a mirror destination port, a network board, a network chip for receiving multicast messages, and a network chip for sending multicast messages. The device includes:

[0089] Configuration module 401, used for the switch to obtain a multicast message after receiving a message sent by an external device, and control the multicast message to be transmitted to the network chip receiving the multicast message through the target multicast structure in the message after data packet processing; the switch is configured based on the multicast communication mechanism;

[0090] A sending module 402, for the network chip receiving the multicast message to obtain a multicast message unit set based on the received multicast message, and send the multicast message unit set to the network board; the multicast message unit set includes a plurality of multicast message units;

[0091] Forwarding module 403, used for the network board to receive the multicast message unit set, and forward the multicast message unit set to the network chip that sends the multicast message, so that the network chip that sends the multicast message reassembles the received multiple multicast message units in the multicast message unit set to obtain a reassembled multicast message; the network chip that sends the multicast message corresponds to the multicast communication mechanism;

[0092] The receiving module 404 is used for the network chip sending the multicast message to send the reassembled multicast message to the service destination port and the mirror destination port in the switch through the target multicast structure, so that the service destination port and the mirror destination port can normally receive the message sent by the external device.
