Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a method, apparatus, device, medium, and product for detecting flow detection capability. Background Technology

[0002] iFIT (In-situ Flow Information Telemetry) is a detection technology that directly detects network performance indicators by marking the features of real network traffic flows. It can directly measure traffic packets to obtain the real packet loss rate, latency, and other performance indicators of the IP network. Compared with out-of-band detection methods that periodically send simulated traffic packets, iFIT is more accurate.

[0003] However, since iFIT technology is a relatively new technology, the support capabilities of devices for iFIT vary. When iFIT is required, existing technologies cannot detect whether the current device has iFIT capabilities. If the current device does not have iFIT capabilities, it will cause service packets to fail to be forwarded normally. Summary of the Invention

[0069] In one embodiment, such as Figure 1 As shown, a method for detecting flow-following capabilities is provided, applied to a detection initiation device, and includes the following steps:

[0070] Step 101: Determine the device to be detected and the corresponding message to be sent.

[0071] Before sending the message to be sent, the probe initiating device determines the device to be probed and the message to be sent corresponding to the device to be probed. The message to be sent contains at least iFIT information and data packets.

[0072] In one possible embodiment, the probe initiating device can determine the message to be sent corresponding to the device to be probed before sending the message to be sent. For example... Figure 2 As shown, Figure 2 An exemplary diagram of the format of the message to be sent is shown. The format of the message to be sent can be Multi-Protocol Label Switching (MPLS) encapsulation or Segment Routing (SR) encapsulation. When the format of the message to be sent is MPLS encapsulation, the message to be sent includes a Layer 2 header, an MPLS header, an MPLS extension header, a Layer 3 header, and message data, wherein the iFIT information is encapsulated in the MPLS extension header. When the format of the message to be sent is SR encapsulation, the message to be sent includes a Layer 2 header, a Layer 3 header, an SR extension header, and message data, wherein the iFIT information is encapsulated in the SR extension header. It should be noted that the format of the message to be sent can also be other formats, and the format of the message to be sent is not limited here.

[0073] Step 102: Construct a probe message for the device to be probed based on the iFIT information in the message to be sent.

[0074] Here, after the probe initiating device determines the device to be probed and the corresponding message to be sent, a probe message can be constructed for the device to be probed based on the iFIT information in the message to be sent.

[0075] In one possible embodiment, constructing a probe message for the device to be probed based on the iFIT information in the message to be sent includes the following steps:

[0076] Obtain detection information of the device to be detected based on iFIT information;

[0077] Insert the detection information into the message to be sent to obtain the detection message of the device to be detected.

[0078] Specifically, after determining the device to be probed and the corresponding message to be sent, the probe initiating device obtains the probe information of the device to be probed based on iFIT information. This probe information includes the type, length, and message identifier of the probe message corresponding to the device to be probed. For example, when the probe initiating device determines that the message to be sent is in SR encapsulation format, it obtains iFIT information from the SR extension header and, based on the iFIT information, obtains the probe information of the device to be probed. This probe information includes the type, length, and message identifier of the probe message corresponding to the device to be probed. The type information can be the type (Type) of the iFIT probe message, the length information can be the length (Length) of the iFIT probe message, and the message identifier can be the message sequence number, service flow code, timestamp, etc., of the iFIT probe message. It should be noted that the probe information may also include other content; the content of the probe information is not limited here. After obtaining the probe information of the device to be probed, the probe initiating device inserts the probe information into the message to be sent, thus obtaining the probe message of the device to be probed.

[0079] Step 103: Send the probe message to the device to be probed.

[0080] Here, after the probe initiating device constructs a probe message for the device to be probed based on the iFIT information in the message to be sent, the probe initiating device sends the probe message to the device to be probed.

[0081] In one possible embodiment, sending a probe message to the device to be probed includes the following steps:

[0082] Obtain the address information of the device to be detected based on iFIT information;

[0083] Based on the address information and the detection direction of at least one device to be detected, the detection path of the device to be detected is determined, and the detection message is sent to the device to be detected according to the detection path.

[0084] Specifically, after the probe initiating device constructs a probe packet for the target device based on the iFIT information in the packet to be sent, the probe initiating device obtains the address information of the target device based on the iFIT information. For example, when the format of the packet to be sent is SR encapsulation, the probe initiating device obtains the iFIT information from the SR extension header of the packet to be sent, and obtains the address information of the target device based on the iFIT information. After obtaining the address information of the target device based on the iFIT information, the probe initiating device determines the probe path for the target device based on the address information and the probe direction for at least one target device, and sends the probe packet to the target device according to the probe path. For example, as shown... Figure 3 As shown, Figure 3An exemplary schematic diagram of the probe path is shown. The probe initiating device is located at the head node in the network, and the device to be probed is located at the middle node or tail node in the network. When the probe initiating device determines that the address information of the device to be probed is the tail node and determines the probe direction of the tail node, the probe initiating device can determine the probe path of the device to be probed and send probe packets to the device to be probed according to the probe path.

[0085] Step 104: Obtain the feedback message sent by the device under test based on the detection message, and determine the flow detection capability of the device under test based on the feedback message.

[0086] Here, after the probe initiating device sends the probe message to the device to be probed, the probe initiating device obtains the feedback message sent by the device to be probed based on the probe message, and determines the flow detection capability of the device to be probed based on the feedback message.

[0087] In one possible embodiment, such as Figure 4 As shown, Figure 4 An exemplary response path diagram is shown. After the probe initiating device at the head node sends the probe message to the device to be probed at the tail node, the probe initiating device obtains the feedback message sent by the device to be probed based on the probe message through the response path. After obtaining the feedback message, the probe initiating device determines the flow detection capability of the device to be probed through the feedback message.

[0088] This disclosure provides a method, apparatus, device, medium, and product for detecting flow-following detection capability. First, a probe initiating device determines a device to be detected and a corresponding message to be sent; wherein the message to be sent includes at least iFIT information and a data packet; then, the probe initiating device constructs a probe message for the device to be detected based on the iFIT information in the message to be sent; subsequently, the probe initiating device sends the probe message to the device to be detected; finally, the probe initiating device obtains a feedback message sent by the device to be detected based on the probe message, and determines the flow-following detection capability of the device to be detected based on the feedback message.

[0089] As described above, before sending a message to be sent, the probe initiating device can construct a probe message for the device to be probed using the iFIT information in the message to be sent, and then send the probe message to the device to be probed. By receiving the feedback message sent by the device to be probed, the probe initiating device can predict in advance whether the device to be probed has the ability to follow the flow for detection, thereby avoiding service interruption caused by the device to be probed not having the ability to follow the flow for detection, and reducing invalid and unresolved traffic in the network, thereby improving network stability.

[0090] In one embodiment, step 102, which involves constructing a probe message for the device to be probed based on the iFIT information in the message to be sent, further includes the following steps:

[0091] If the message to be sent contains an SR extension header, the probe information is encapsulated in the SR extension header to obtain a probe message;

[0092] If the message to be sent contains an MPLS extension header, the probe information is encapsulated in the MPLS extension header to obtain a probe message;

[0093] The probe information is encapsulated in a data packet to obtain the probe packet.

[0094] Specifically, in one possible embodiment, after the probe initiating device obtains the probe information of the device to be probed based on iFIT information, it inserts the probe information into the message to be sent to obtain the probe message of the device to be probed. For example, as shown below... Figure 5 As shown, Figure 5 An exemplary schematic diagram of the probe message format is shown. When the message to be sent is in SR encapsulation format, the message to be sent contains an SR extension header. The probe information is encapsulated in the SR extension header of the message to be sent to obtain a probe message containing the probe information.

[0095] In another possible embodiment, when the message to be sent is encapsulated in MPLS format, the message to be sent includes an MPLS extension header. The probe information is encapsulated in the MPLS extension header of the message to be sent, resulting in a probe message containing the probe information.

[0096] In another possible embodiment, the probe information can also be encapsulated in the data packet of the message to be sent using the Internet Control Message Protocol (ICMP) to obtain a probe message. It should be noted that, in addition to the methods described in the three embodiments above, other methods can also be used to encapsulate the probe information. The specific encapsulation method is not limited here, and the method that can be implemented is the standard.

[0097] In this embodiment, after obtaining the probe information of the device to be probed based on iFIT information, the probe initiating device obtains a probe packet containing the probe information by inserting the probe information into the SR extension header or MPLS extension header of the packet to be sent, or by encapsulating the probe information in the data packet of the packet to be sent. The probe initiating device can select an appropriate encapsulation form to encapsulate the probe information according to the actual situation, making the flow detection method applicable to more scenarios and improving the flexibility of the detection method.

[0098] In one embodiment, such as Figure 6As shown, step 104, which determines the flow detection capability of the device to be detected based on the feedback message, also includes the following steps:

[0099] Step 601: Extract the iFIT probe response information from the feedback message.

[0100] After the probe initiating device obtains the feedback message sent by the device to be probed based on the probe message, it extracts the iFIT probe response information from the feedback message.

[0101] In one possible embodiment, exemplarily, such as Figure 7 As shown, Figure 7 An exemplary schematic diagram of the feedback message format is shown. The probe initiating device obtains the feedback message. The SR extension header of the feedback message contains iFIT probe response information. The probe initiating device extracts the iFIT probe response information contained in the SR extension header.

[0102] Step 602: Determine the flow detection capability of the device to be detected based on the iFIT detection response information.

[0103] After the probe initiating device extracts the iFIT probe response information from the feedback message, it determines the flow detection capability of the device to be probed based on the iFIT probe response information.

[0104] In one possible embodiment, determining the flow detection capability of the device to be detected based on iFIT probe response information includes the following steps:

[0105] The iFIT detection response information is compared with the detection information of the device to be detected to obtain the comparison results;

[0106] If the comparison results are consistent, it is determined that the device to be detected has the ability to detect along the flow.

[0107] If the comparison results are inconsistent, it is determined that the device to be detected does not have the ability to detect along with the flow.

[0108] Specifically, after the probe initiating device extracts the iFIT probe response information from the feedback message, it compares the iFIT probe response information with the probe information of the device to be probed, and obtains the comparison result. The probe information includes the type information, length information, and message identifier of the probe message corresponding to the device to be probed. If the comparison results of the type information, length information, and message identifier of the iFIT probe response information and the type information, length information, and message identifier of the probe message are consistent, then it is determined that the device to be probed has the capability for flow-following detection, the detection process is completed, and the probe initiating device subsequently executes normal iFIT detection. The FIT message sending process: If the comparison results of the type information, length information, and message identifier of the iFIT probe response information and the type information, length information, and message identifier of the probe message are inconsistent, it is determined that the device to be probed does not have the ability to perform flow-following detection. Subsequently, depending on whether the network service is in end-to-end detection (E2E) mode or hop-by-hop (Trace) detection mode, it is determined whether the device without iFIT capability affects the iFIT service. If it does not affect the service, the probe initiating device continues to perform normal iFIT message sending; if it does affect the service, it can report warnings to upstream devices or network management systems.

[0109] In this embodiment, firstly, the probe initiating device extracts the iFIT probe response information from the feedback message. Then, the probe initiating device obtains the comparison result by comparing the iFIT probe response information with the probe information of the device to be probed. Finally, the probe initiating device determines the flow detection capability of the device to be probed based on the comparison result, thereby improving the reliability of the flow detection capability detection method.

[0110] In one embodiment, such as Figure 8 As shown, a method for detecting flow-following capabilities is provided, applied to the device to be detected, and includes the following steps:

[0111] Step 801: Obtain the probe message sent by the probe initiating device.

[0112] Here, the probe initiating device constructs a probe message for the device to be probed based on the iFIT information in the message to be sent, and sends the probe message to the device to be probed according to the probe path. The device to be probed then obtains the probe message sent by the probe initiating device. The probe message is determined by a detection method applied to the flow detection capability of the probe initiating device; the process of obtaining the probe message will not be described in detail here.

[0113] Step 802: Generate a feedback message based on the probe message and send the feedback message back to the probe initiating device.

[0114] Here, after the device to be probed receives the probe message sent by the probe initiating device, the device to be probed generates a feedback message based on the probe message and sends the feedback message back to the probe initiating device.

[0115] In one possible embodiment, generating a feedback message based on the probe message includes the following steps:

[0116] iFIT probe response information is generated based on the probe information of the device to be probed in the probe message;

[0117] Insert the iFIT probe response information into the probe message to obtain the feedback message.

[0118] Specifically, after the device to be probed receives the probe message sent by the probe initiating device, the device to be probed parses the probe message and generates iFIT probe response information based on the probe information in the probe message. After generating the iFIT probe response information, the device to be probed inserts the iFIT probe response information into the probe message to obtain a feedback message. For example, as follows... Figure 7 As shown, Figure 7 An exemplary schematic diagram of the feedback message format is shown. After the device to be probed generates iFIT probe response information, it inserts the iFIT probe response information into the SR extension header of the probe message. The iFIT probe response information includes the type information, length information, and message identifier of the probe message corresponding to the device to be probed. After the device to be probed receives the feedback message, it sends the feedback message back to the probe initiating device. The probe initiating device can determine the flow detection capability of the device to be probed based on the iFIT probe response information in the feedback message.

[0119] In this embodiment, the device under test acquires the probe message sent by the probe initiating device, then the device under test generates a feedback message based on the probe message and sends the feedback message back to the probe initiating device. The feedback message is used by the probe initiating device to determine the flow detection capability of the device under test based on the iFIT probe response information in the feedback message. This allows the probe initiating device to know in advance whether the device under test has flow detection capability, thereby avoiding service interruption caused by the device under test not having flow detection capability. It can also reduce invalid and unresolved traffic in the network, thereby improving network stability.

[0120] In the case of dividing each functional module according to its corresponding functions, this disclosure provides a detection device for flow detection capability, which is set in the detection initiation device. The detection device for flow detection capability can be a server or a chip applied to a server.
