Description

Technical Field

[0001] The disclosed embodiments relate to the technical field of cloud computing, and in particular to a cloud network message tracing method and related equipment. Background Art

[0002] In a public cloud environment, each cloud tenant has an isolated virtual network. When processing computing tasks, if the tenant's computing resources (virtual machines / containers) want to access resources in other locations or provide services to the outside world, they need to communicate data packets with the outside world through the virtual network. When the data packets of tenant services are forwarded through network devices, if any network device in the data transmission link fails, data packets will be lost, causing damage to the tenant's services. Therefore, cloud service providers need to quickly locate the packet loss location so that they can take corresponding measures to restore network services in a timely manner.

[0003] Currently, when tenants have packet loss problems, it often manifests as no response to the connection or request. Packet loss may occur in the request direction, that is, the forward path, or in the response direction, that is, the reverse path. Therefore, to accurately locate the packet loss, it is necessary to track the message on both the forward and reverse paths.

[0004] However, in the conventional message tracking solution, the reverse tracking of messages needs to be manually configured to be implemented, which leads to problems such as low efficiency and poor accuracy of message tracking. Summary of the invention

[0005] The embodiments of the present disclosure provide a cloud network message tracing method and related equipment, which can realize automatic tracing of forward and reverse messages without manual configuration, thereby improving the efficiency and accuracy of message tracing.

[0019] The present embodiment provides a cloud network message tracing method and related equipment. After receiving a forward message with coloring information sent by an upstream device, a coloring connection record of the forward message is generated through a slow path, and the forward message is sent to a downstream device through a fast path.

On the other hand, the outgoing message tracking is automatically triggered by the forward message tracking, avoiding the performance overhead of executing rule matching on multiple devices in the prior art.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0032] The application scenarios of the embodiments of the present disclosure are explained below:

[0033] Figure 1An application scenario diagram of the cloud network message tracing method provided in the embodiment of the present disclosure. The cloud network message tracing method provided in the embodiment of the present disclosure can be applied to the application scenario of message tracing. More specifically, the execution subject of this embodiment can be a network device running the above-mentioned message forwarding function, or other electronic devices that perform similar functions. Among them, in some embodiments, the network device can implement the cloud network message tracing method provided in the embodiment of the present application by running various computer executable instructions or computer programs. For example, computer executable instructions can be program-level commands, machine instructions or software instructions. The computer program can be a native program or software module in the operating system; it can be a local application, that is, a program that needs to be installed in the operating system to run. The above-mentioned computer executable instructions can be instructions in any form, and the above-mentioned computer program can be an application, module or plug-in in any form. The specific implementation form can be configured as needed. Furthermore, in some embodiments, the network device can be an independent physical device, a device cluster or a distributed system composed of multiple physical devices, or a virtual device that provides basic cloud computing services such as cloud services, cloud storage, cloud communications, cloud databases, cloud computing, cloud functions, network services, middleware services, domain name services, security services, content delivery networks (CDNs), and big data and artificial intelligence platforms.

[0034] refer to Figure 1 As shown in the figure, the data packet of the tenant service (shown as an uncolored message) will be forwarded by multiple network devices (shown as network device A, network device B, etc.) during the transmission along the data transmission path. The network device can be a virtual network device or a physical network device. In this process, the network analysis center will issue a data tracking task to the network controller. After that, the network controller will issue a coloring rule to the starting network device (i.e., network device A) corresponding to the starting node of the data transmission path. After that, the starting network device will mark the data passing through it, that is, the uncolored message sent to the starting network device will be colored, and then a colored message will be generated and sent to the downstream network device, i.e., network device B. And so on, until the colored message is sent to the final target device, the forward transmission of the message is completed, and the message is also called a forward message. In this process, after receiving the above-mentioned colored message, each network device will upload the record information to the network analysis center. The network analysis center obtains the last position of the message by restoring the path passed by the message to locate the packet loss position, thereby realizing the tracking of the colored message and achieving the purpose of locating the fault of the subsequent abnormal network device.

[0035] In the prior art, reference Figure 1As shown in , by sending the coloring rules to the starting network device through the network controller, only the coloring of the forward message can be realized, thereby realizing the message tracking during the forward message transmission process. However, the cause of the packet loss problem can occur in the path of the message request (forward message sending) or in the path of the message response (reverse message sending). Therefore, to accurately locate the packet loss position, it is necessary to color and track the message on the path in both directions at the same time. In the scheme of the prior art, on the one hand, there is a situation where the reverse message coloring rules cannot be extracted and configured and issued, that is, when the message passes through the virtual network device in the path, the address port information of the initial message (such as passing through the load balancer, NAT gateway, etc.) or the virtual network identifier (such as passing through the virtual switch, virtual network gateway, etc. when sent to the peer private network) may be changed. At this time, it is necessary to wait for the forward message tracking result, and then derive the coloring rules of the reverse message from it for configuration and issuance, but it is impossible to directly achieve simultaneous tracking. On the other hand, since the device type of the starting point of the reverse path cannot be directly determined based on the destination address of the forward message, there is a situation where the starting network device of the reverse path cannot be accurately located. This results in the inability to color the reverse message, making it impossible to achieve positioning and tracking during the reverse transmission of the message, affecting the accuracy of locating the packet loss location.

[0036] The disclosed embodiment provides a cloud network message tracing method to solve the above-mentioned problem.

[0037] refer to Figure 2 , Figure 2 Schematic diagram of the process of cloud network message tracing method provided by the embodiment of the present disclosure Figure 1 The method of this embodiment can be applied in a network device. The cloud network message tracing method includes:

[0038] Step S101: After receiving a forward message with coloring information sent by an upstream device, a coloring connection record of the forward message is generated through a slow path, and the forward message is sent to a downstream device through a fast path. The coloring connection record contains the coloring information of the forward message, which is used for matching coloring of the reverse message.

[0039] refer to Figure 1 As shown in the schematic diagram of the application scenario, in this embodiment, the provided cloud network message tracing method is introduced with a network device located in the data transmission path as the execution subject. By way of example, the network device can be a physical network device or a virtual network device. The functional structure of the network device is first introduced below. Figure 3 A schematic diagram of a network structure provided by an embodiment of the present disclosure is shown in FIG. Figure 3As shown, a slow path (SP) forwarding unit and a fast path (FP) forwarding unit are deployed in the network structure. When forwarding a message, the received message is processed by two different processing methods, namely the fast path and the slow path. The fast path uses the forwarding flow table to quickly forward the message in a match-action manner, wherein the match refers to matching the network communication identification information of the received message, such as the IP address, network port, transmission protocol, virtual network identification, etc., that is, for example, five-tuple information, so as to realize the identification of a specific message; and the action refers to the operation performed on the message after matching the message, such as forwarding the message after modifying the address. The slow path maintains the connection record and generates a corresponding forwarding flow table according to the configuration and policy instructions of the fast path. Fast path and slow path are existing concepts in network protocols, and their implementation methods are not repeated here. The slow path and fast path in this embodiment are respectively used to implement a functional unit for forwarding messages based on a slow path and a functional unit for forwarding messages based on a fast path.

[0040] Furthermore, combined with Figure 1 As shown in the schematic diagram of the application scenario, in this embodiment, the upstream device is a network device located upstream of the target network device as the execution subject of this embodiment in the data transmission path, more specifically, a network device located at the previous hop of the target network device. During the forward transmission of the message, the upstream network device determines that the target network device is a startled network device through routing calculation, and then sends the message (i.e., the forward message) to the target network device, and the target network device continues to forward the forward message. Specifically, the target network device first receives the forward message with coloring information through the fast path, and then sends the forward message with coloring information to the slow path, and the slow path searches according to the network communication identification information of the forward message to confirm whether the corresponding message connection record already exists. If the message connection record already exists, the message connection record is a kind of information used to establish a forwarding flow table in the fast path, thereby realizing the fast forwarding of the message. The message that has been forwarded will establish and maintain a message connection record in the slow path. This embodiment aims at the situation where the message connection record is not established. Specifically, after the slow path searches according to the network communication identification information of the forward message, no matching message connection record is found. In this case, a coloring connection record of the forward message is generated through the slow path. Unlike the traditional message connection record, the coloring connection record additionally includes coloring information of the forward message to realize the subsequent coloring of the reverse message, that is, for matching coloring of the reverse message.

[0041] Furthermore, after generating a colored connection record for the forward message through the slow path, the slow path sends the forward message back to the fast path. The fast path creates a forwarding flow table through the above colored connection record, and then sends the forward message with the colored information to the downstream device. The downstream device is the network device located at the next hop of the target network device in the data transmission path. The target network device records the target IP address in the forward message received. After that, the target network device determines the next hop network address by querying the forwarding routing table, thereby determining the next hop network device, thereby realizing message forwarding.

[0042] In a possible implementation, the coloring information includes a Differentiated Services Code Point (DSCP) located in the header of the forward message, such as Figure 4 As shown, the specific implementation of step S101 includes:

[0043] Step S1011: Obtain network communication identification information of the forward message.

[0044] Step S1012: Generate a message connection record corresponding to the network communication identification information through the slow path. The message connection record is used to generate a forwarding flow table in the fast path. The forwarding flow table is used to indicate the forwarding rules of the fast path when forwarding messages.

[0045] Step S1013: Write the differentiated services code point of the forward message into the message connection record to generate a colored connection record of the forward message.

[0046] Exemplarily, the network communication identification information of the message, the network communication identification information refers to the source IP address, source port, destination IP address, destination port and transport layer protocol. The network communication identification information is carried in the message and is used to implement parsing and forwarding of the message. The specific method of obtaining the network communication identification information of the message is based on the existing technology of the network protocol and is not repeated here. After obtaining the network communication identification information of the forward message, the slow path will generate a corresponding message connection record based on the above network communication identification information. The message connection record is used to generate information of the forwarding flow table on the fast path. The forwarding flow table is used to indicate the forwarding rules of the fast path when forwarding the message, so that when a message with the same or similar network communication identification information is received, the corresponding connection record and forwarding flow table can be matched. Finally, the differential service code point of the forward message is written into the message connection record through the slow path, thereby generating a coloring connection record containing coloring information (differential service code point).

[0047] Among them, further, after generating the dye connection record through the slow path and sending the forward message to the fast path, it is necessary to generate a corresponding forwarding flow table based on the dye connection record, that is, after step S1013, it also includes:

[0048] Step S1014: Based on the dyed connection record, a target forwarding flow table for the network communication identification information is generated in the fast path.

[0049] Step S1015: Send the forward message to the corresponding target downstream device through the fast path based on the target forwarding flow table.

[0050] Exemplarily, after generating the dye connection record, the fast path generates "match-action" information corresponding to the network communication identification information based on the content indicated by the message connection record part in the dye connection record, where the content of the matching part can be part or all of the network communication identification information, and then directly executes the corresponding action after receiving similar or identical network communication identification information, thereby realizing the fast forwarding of the message. In this message forwarding link, the fast path calculates the address of the next hop based on the target forwarding flow table, and sends the forward message to the corresponding target downstream device, and this process is not repeated.

[0051] Step S102: after receiving the reverse message sent by the downstream device, the reverse message is sent to the slow path, and a processing rule for the reverse message is generated according to the dye connection record.

[0052] Step S103: The reverse message is processed based on the processing rule through the fast path to obtain a reverse message with coloring information, and the reverse message with coloring information is sent to the upstream device.

[0053] Exemplarily, after the forward message is forwarded, the forward message finally reaches the final receiving end, such as a server, and executes the action requested by the forward message. After that, the server sends the result of the action execution in the reverse path, and finally reaches the initiating device of the forward message, so that the initiating device obtains the response result corresponding to the forward message. The process of reverse transmission of the message is the process of sending the reverse message.

[0054] In this embodiment, after the target network device obtains the reverse message sent by its downstream device through the fast path, the reverse message is first sent to the slow path, and then the processing rule of the reverse message is generated according to the dyeing connection record stored in the slow path. Wherein, the processing rule includes at least one matching value, and the matching value corresponds to at least one action item, wherein the matching value is used to indicate the network communication identification information of the message, and the action item is used to indicate the operation performed on the message. In this embodiment, the action item in the processing rule is used to indicate the corresponding dyeing operation performed on the reverse message. Then, the reverse message is processed based on the processing rule to obtain a reverse message with dyeing information, thereby solving the problem in the prior art that the processing rule of the reverse message cannot be configured, resulting in the inability to dye it. Specifically, after receiving the reverse message sent by the downstream device, when it is detected that the reverse message is not dyed, a rule "for dyeing and forwarding the message" is generated using the dyeing connection record. Based on the rule, a special forwarding flow table is generated, so that before forwarding the reverse message through the fast path, the message is dyed, and a reverse message with dyeing information is generated.

[0055] Figure 5 A schematic diagram of a process for generating a reverse message with coloring information provided by an embodiment of the present disclosure, such as Figure 5 As shown, exemplarily, first, the target network device receives the uncolored reverse message 0_Msg_a sent by the downstream device through the fast path, and then the fast path sends the uncolored reverse message 0_Msg_a to the slow path, and the slow path compares the network communication identification information of the reverse message 0_Msg_a to confirm that the corresponding colored connection record Info_Msg_a with colored information of the forward message 1_Msg_a is stored in the slow path. Then, the colored connection record Info_Msg_a is used to generate the corresponding processing rule Case_a, wherein the processing rule Case_a corresponds to two execution actions, namely action_1 and action_2, wherein action_1 is used to generate the forwarding flow table flow_a corresponding to 0_Msg_a, and action_2 is used to insert the colored information (i.e., colored) into the reverse message 0_Msg_a. After that, the reverse message 0_Msg_a is processed by executing the above action_1 and action_2 through the fast path to generate a reverse message 1_Msg_a with coloring information, and the reverse message 1_Msg_a is forwarded based on the forwarding flow table flow_a generated in the above steps.

[0056] In this embodiment, after receiving a forward message with coloring information sent by an upstream device, a coloring connection record of the forward message is generated through a slow path, and the forward message is sent to a downstream device through a fast path, and the coloring connection record contains the coloring information of the forward message; after receiving a reverse message sent by a downstream device, the reverse message is sent to a slow path, and a processing rule for the reverse message is generated according to the coloring connection record; through a fast path, the reverse message is processed based on the processing rule to obtain a reverse message with coloring information, and the reverse message with coloring information is sent to the upstream device. After receiving a forward message, a coloring connection record of the forward message is generated, and then after receiving a reverse message, the reverse message is colored using the coloring connection record of the forward message to obtain a reverse message with coloring information, thereby solving the problem that the reverse message cannot be colored, realizing simultaneous tracking and association of forward and reverse messages under the same connection, and then realizing the location of abnormal network devices when packet loss occurs, and improving the accuracy of locating the packet loss position. At the same time, on the one hand, since the general process of stateful virtual network devices is reused to match the coloring of outgoing messages, development costs and performance overhead are saved. The coloring rules of reverse messages are generated in real time, avoiding manual configuration and distribution processing, eliminating the complexity and performance overhead of configuration distribution, thereby improving message tracking efficiency. On the other hand, outgoing message tracking is automatically triggered by forward message tracking, avoiding the performance overhead of executing rule matching on multiple devices in the existing technology.

[0057] refer to Figure 6 , Figure 6 Schematic diagram of the process of cloud network message tracing method provided by the embodiment of the present disclosure Figure 2 In this embodiment Figure 2 On the basis of the illustrated embodiment, steps S102-S103 are further refined, and the cloud network message tracing method includes:

[0058] Step S201: After receiving a forward message with coloring information sent by an upstream device, a coloring connection record of the forward message is generated through a slow path, and the forward message is sent to a downstream device through a fast path. The coloring connection record contains the coloring information of the forward message, which is used for matching coloring of the reverse message.

[0059] Step S202: after receiving the reverse message sent by the downstream device, send the reverse message to the slow path.

[0060] Step S203: Detect the coloring status of the reverse message through the slow path, and determine the corresponding target processing rule according to the coloring status.

[0061] Exemplarily, after the target network device receives the reverse message sent by the downstream device through the fast path, the undyed reverse message is sent to the slow path for processing. Specifically, the target network device generates a corresponding message connection record through the slow path to forward the reverse message on the fast path side. In this process, the slow path detects the dyeing state of the reverse message and determines the corresponding target processing rule according to the dyeing state. Among them, the dyeing state includes an undyed state and a dyed state. The undyed state is a state in which the message header field does not carry dyeing information, and the dyeing state is a state in which the message header field carries dyeing information. Specifically, when the reverse message is in an undyed state, it needs to be dyed so that it carries dyeing information, and when it is in a dyed state, it does not need to be dyed again, thereby reducing resource overhead.

[0062] For example, Figure 7 As shown, the specific implementation of step S203 includes:

[0063] Step S2031: Detect the header field of the reverse message to obtain the coloring status of the reverse message.

[0064] Step S2032: If the reverse message is in an uncolored state, the target processing rule is the first processing rule, which is used to generate a first forwarding flow table in the fast path, and the first forwarding flow table is used to insert coloring information into the reverse message and forward the reverse message.

[0065] Step S2033: If the reverse message is in a dyed state, the target processing rule is the second processing rule, the second processing rule is used to generate a second forwarding flow table in the fast path, and the second forwarding flow table is used to forward the reverse message.

[0066] Exemplarily, in a specific implementation, the slow path determines the coloring state of the reverse message by detecting the header field of the reverse message, that is, whether the differential service code point is written. If the reverse message is in an uncolored state, that is, the differential service code point is not written in the header field, the first processing rule is determined to be the target processing rule; conversely, if the reverse message is in a colored state, that is, the differential service code point is written in the header field, the second processing rule is determined to be the target processing rule. Among them, the first processing rule and the second processing rule are both pre-set rules and can be implemented by specific methods and functions. In one case, after the first processing rule is determined, a corresponding first forwarding flow table will be generated in the fast path, and the first forwarding flow table is used to insert coloring information in the reverse message and forward the reverse message; in another case, after the second processing rule is determined, a corresponding second forwarding flow table will be generated in the fast path, and the second forwarding flow table is used to forward the reverse message without inserting coloring information.

[0067] Step S204: Generate a corresponding target forwarding flow table in the fast path through the slow path based on the target processing rule, and the target forwarding flow table includes forwarding action items and coloring processing action items.

[0068] Further, in combination with the previous steps, after determining the target processing rule, a corresponding target forwarding flow table is generated in the fast path based on the target processing rule, that is, if the target processing rule is the first processing rule, a first forwarding flow table is generated in the fast path, and if the target processing rule is the second processing rule, a second forwarding flow table is generated in the fast path. Among them, exemplarily, when the target forwarding flow table is the first forwarding flow table, the target forwarding flow table contains a forwarding action item (action_1) and a coloring processing action item (action_2). When the target processing rule is the first processing rule, the corresponding value of the corresponding forwarding action item is the corresponding forwarding action content, such as a specific modification address, and a forwarding instruction for forwarding based on the modified address, and the corresponding value of the coloring processing action item is an instruction to insert coloring information. When the target forwarding flow table is the second forwarding flow table, the target forwarding flow table contains a forwarding action item (action_1).

[0069] Optionally, after step S204, the method further includes:

[0070] Step S204A: Delete the dyed connection record of the forward message stored in the slow path.

[0071] Exemplarily, after the target forwarding flow table is generated, the coloring process of the reverse message has been completed. After that, whenever the reverse message with the coloring information is forwarded, the path it passes through will be recorded, thereby achieving the purpose of tracking it. Therefore, the reverse message received later can no longer be colored, thereby saving the system's resource overhead. Therefore, after the target forwarding flow table is generated, the coloring connection record of the forward message stored in the slow path is deleted, so that when the next reverse message is received, since the slow path no longer stores the coloring connection record, the target network device will not color the reverse message based on the coloring connection record, thereby achieving the purpose of saving system resources and reducing resource overhead.

[0072] Step S205: through the fast path, based on the coloring processing action item, the coloring information is written into the reverse message to obtain a reverse message with the coloring information.

[0073] Step S206: Send the reverse message of the coloring information to the upstream device through the fast path based on the forwarding action item.

[0074] Exemplarily, after generating the target forwarding flow table, the fast path will perform the corresponding processing steps according to the action indicated by the above target forwarding flow table, that is, based on the coloring processing action item, the coloring information is written into the reverse message to obtain a reverse message with coloring information. After that, the fast path performs the message forwarding action based on the forwarding action item, and sends the reverse message with coloring information to the upstream device. Among them, the coloring information is the coloring information carried in the forward message corresponding to the reverse message, so that the request message and the response message can have the same coloring information, thereby realizing the complete tracking of the forward path and reverse path of the same request.

[0075] Optionally, after step S206, the method further includes:

[0076] Step S207: Generate a sending and receiving record for the forward message with coloring information and / or the reverse message with coloring information.

[0077] Step S208: Send the sending and receiving records to the data tracking server.

[0078] Exemplarily, after the target network device completes forwarding of the forward message with the coloring information and / or the reverse message with the coloring information, it generates a corresponding transceiver record based on the coloring information. The transceiver record may include the transceiver time and the corresponding device information, indicating that the target network device has received the message with the above coloring information. Afterwards, the target network device sends the transceiver record to the data tracking server, for example Figure 1 The network analysis center in the application scenario diagram shown in the figure, and the data tracking server further processes the sending and receiving records to locate the packet loss location.

[0079] Exemplarily, the transceiver record includes at least one of the following: the location of the target network device in the message forwarding path, the device identification of the target network device, the device identification of the next-hop network device, and the network communication identification information of the forward message and / or the reverse message.
