The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
Referring to fig. 1, fig. 1 is a communication device 10 provided in this embodiment, the communication device 10 may include one or more forwarding chips 100, and the forwarding chip 100 may include (or control) one or more communication ports 111. Each communication port 111 includes a packet buffer queue for receiving or transmitting packets.
The communication device 10 further comprises a packet loss detection module 200. In an implementation manner of this embodiment, referring to fig. 1 again, the packet loss detection module 200 may be a packet loss detection module 200 provided by the forwarding chip 100, and is configured to perform packet loss detection on the communication port 111 included (or controlled) by the forwarding chip 100. For example, the packet loss detection module 200 may be a TCB (Transient Capture Buffer) module.
In another implementation manner of this embodiment, referring to fig. 2, the packet loss detection module 200 may also be a module capable of performing packet loss detection on the communication ports 111 included (or controlled) by different forwarding chips 100. That is, one packet loss detection module 200 may be used to detect packet loss of the communication ports 111 included or controlled by the plurality of forwarding chips 100.
Referring to fig. 3, in this embodiment, the packet loss detection module 200 may include a packet loss information buffer queue for recording packet loss information of the currently detected communication port 111. The packet loss information buffer queue may include a packet record queue and a packet loss event queue.
The message record queue may be a circular queue, and is configured to store, in a circular coverage manner, field message data stored when no packet loss occurs in a message buffer queue of the currently detected communication port 111.
The packet loss event queue is used to store packet loss event information of the currently detected communication port 111 when packet loss occurs, for example, information including a discard reason, a queue where a packet is located, a usage rate of the queue, a timestamp, and the like.
Referring to fig. 4, fig. 4 is a flowchart illustrating a port packet loss detection method applied to the communication device 10 according to this embodiment. In this embodiment, the method includes step S110 and step S120, and each step is explained in detail below.
In step S110, the packet loss detection module 200 is controlled to perform packet loss detection for a preset time length on a plurality of communication ports 111 to be detected (hereinafter referred to as "ports to be detected") one by one, so as to detect whether packet loss occurs in each port to be detected.
In some cases, the communication device 10 may have a plurality of communication ports 111, but only a part of the communication ports 111 may need to be subjected to packet loss detection. Therefore, in this embodiment, the packet loss detection module 200 stores a to-be-detected port list in advance, the to-be-detected port list records port information of the communication port 111 that needs to perform packet loss detection, and in the detection process, the communication port 111 recorded in the to-be-detected port list is used as the to-be-detected port.
In order to intuitively and conveniently manage and control the packet loss detection module 200 and the port list to be detected, in this embodiment, please refer to fig. 5, a corresponding packet loss detection module software node may be configured in advance for the packet loss detection module 200. The port list to be detected may be configured in the packet loss detection module software node, so that the packet loss detection module 200 may perform packet loss detection according to the port information recorded in the port list to be detected.
The communication device 10 may further adjust the port to be tested recorded in the port to be tested list in response to the received port to be tested adjustment instruction. For example, any one or more of port addition, port deletion, and port modification are performed. The detection range of the packet loss detection module 200 can be managed and controlled by managing the port list to be detected.
In this embodiment, each port to be detected may correspond to a detection flag for indicating whether the corresponding port to be detected has been detected by the packet loss detection module 200. For example, the detection flag may be a flag bit of 1 bit, setting the detection flag to 1 indicates that the corresponding port to be detected has been detected by the packet loss detection module 200, and setting the detection flag to 0 indicates that the corresponding port to be detected has not been detected by the packet loss detection module 200.
Referring to fig. 5 again, the packet loss detection module software node may include a monitoring object state sequence, and in the monitoring object state sequence, a detection mark corresponding to each port to be detected is recorded.
When detecting a plurality of ports to be detected, the communication device 10 may select one of the ports to be detected that is not detected as a target port to be detected from the ports to be detected recorded in the port list to be detected according to the detection flag of each port to be detected.
Different detection policy information may be required for different ports to be detected, so in this embodiment, the ports to be detected may correspond to preset detection policy information, and the detection policy information may include configuration information such as a queue type (e.g., a receiving queue or a sending queue) of the ports to be detected, a sampling rate of a buffer packet, and the like.
Referring to fig. 6, in this embodiment, a corresponding port-to-be-tested software node may also be generated for each port to be tested in advance, and the detection policy information may be configured in the port-to-be-tested software node.
After the target port to be detected is determined, the detection policy information of the target port to be detected is obtained, and then the packet loss detection module 200 is controlled to detect the target port to be detected for a preset time (for example, 50ms) according to the detection policy information. Therefore, the packet loss detection module 200 can perform automatic cycle detection on the ports 111 to be detected according to the detection strategy information of different ports to be detected, and compared with the existing method for detecting through manual configuration, the method is higher in efficiency and less prone to errors.
In this embodiment, after the current target port to be detected is detected, the detection flag of the target port to be detected may be further modified, so that the detection flag indicates that the target port to be detected is detected, for example, the detection flag of the target port to be detected is modified to 1, and then another port to be detected is reselected as the target port to be detected for packet loss detection.
In addition, when the detection mark indication of each port to be detected is detected, the detection mark of each port to be detected can be modified, so that the port to be detected corresponding to each detection mark indication is not detected, and then a new round of packet loss detection is performed. For example, when the detection marks of all the ports to be detected are 1, it is determined that all the ports to be detected have been detected in the current round, the detection marks of all the ports to be detected are modified to be 0, and then a new round of detection is started.
Thus, by time-sharing multiplexing of the packet loss detection module 200, automatic detection of a plurality of ports to be detected by one packet loss detection module 200 can be realized.
Further, in this embodiment, please refer to fig. 5 again, the packet loss detection module 200 further has a packet loss state identifier configured in the software node of the packet loss detection module, where the packet loss state identifier is used to indicate whether the port to be detected currently detected by the packet loss detection module 200 has a packet loss.
In the process of detecting a plurality of ports to be detected, the communication device 10 detects the packet loss state identifier of the packet loss detection module 200, and determines whether the port to be detected currently detected by the packet loss detection module 200 has a packet loss according to the packet loss state identifier.
If the packet loss state identifier indicates that the currently detected port to be detected has a packet loss, the method goes to step S120; if the packet loss state identifier does not indicate that the currently detected port to be detected has packet loss within the preset time length, modifying the detection mark of the target port to be detected to enable the detection mark to indicate that the target port to be detected is detected, and then reselecting the next port to be detected for detection.
In step S120, the packet loss information of the currently detected port to be detected, recorded by the packet loss detection module 200, is stored in the information cache region corresponding to the port to be detected.
In this embodiment, referring to fig. 6 again, each port to be tested corresponds to one information buffer. The information cache region comprises a first information cache region and a second information cache region. The first information cache region is used for storing packet loss information when packet loss occurs at present, and the second information cache region is used for storing packet loss information when packet loss occurs last time.
When detecting that the port to be tested loses the packet in step S110, the communication device 10 may store the data currently recorded in the first information cache region of the port to be tested in the second information cache region, and then store the packet loss information recorded by the packet loss detection module 200 in the first information cache region.
Therefore, when packet loss occurring in the port to be tested needs to be analyzed, current and previous packet loss information of the port to be tested can be directly read, and analysis can be more convenient and accurate.
Further, in this embodiment, each port to be tested may further include corresponding port information, for example, a port number of the port to be tested, a chip number of the forwarding chip 100 to which the port to be tested belongs, and the like.
When packet loss analysis needs to be performed on a certain port to be analyzed, the communication device 10 may obtain port information of the port to be analyzed, determine an information cache region corresponding to the port to be analyzed according to the port information, and read packet loss information in the information cache region for further analysis.

And the selecting submodule 311 is configured to select an undetected port to be detected as a target port to be detected according to the detection flag of each port to be detected.
Further, in this embodiment, the communication device 10 stores a list of ports to be tested in advance, and the list of ports to be tested records port information of each port to be tested.
The selecting submodule 311 is configured to select, according to the detection flag of each port to be detected recorded in the port to be detected list, one undetected port to be detected as a target port to be detected.
The detection sub-module 312 is configured to control the packet loss detection module 200 to perform packet loss detection on the target port to be detected for a preset time period, and modify the detection mark of the target port to be detected after the detection is completed, so that the detection mark indicates that the target port to be detected has been detected.
Further, in this embodiment, the port to be tested has corresponding preset detection policy information. The detection sub-module 312 obtains the detection policy information of the target port to be detected, and controls the packet loss detection module 200 to perform detection on the target port to be detected for a preset time according to the detection policy information.
The reset submodule 313 is configured to modify the detection mark of each port to be detected when the detection mark of each port to be detected indicates that the port to be detected is not detected.

Further, in this embodiment, the port packet loss detection apparatus 300 may further include a modification module.
And the modification module is used for responding to the received port to be tested adjustment instruction and adjusting the port to be tested recorded in the port list to be tested, wherein the adjustment comprises any one or more of port addition, port deletion and port modification.
