[0072] Before introducing the embodiments of this application, the relevant technologies will be described first:

[0073] Most SD-WAN solutions centrally manage and control an enterprise's wide area network (WAN) nodes through an SD-WAN controller. This controller then centrally schedules application-based packet forwarding based on the overall network resource status and utilizes Quality of Service (QoS) policies for quality assurance. However, this approach views the Overlay (virtual network) and Underlay (physical network) as separate entities, and the cloud and network as separate entities, leading to inflexible cloud and network service quality. For example, to guarantee high-quality service, a dedicated line must be used to connect to the enterprise's WAN nodes and run SD-WAN to ensure Service Level Agreements (SLAs).

[0074] The concept of Wide Area Network (WAN) aims to leverage SRv6 technology to integrate network resources from an end-to-end perspective by converging Underlay and Overlay networks, thereby achieving the integration of cloud and network capabilities and providing network plus cloud product services. Figure 1 This document illustrates an architecture example of an SRv6-based SD-WAN system. The SRv6-based SD-WAN system includes: a Smart WAN controller (also known as an SD-WAN controller), a bearer network controller (also known as a cloud backbone controller), edge routers (PE, Provider Edge), CPE, and PoP, among others.

[0075] The CPE has added functions such as SRv6 / G-SRv6 tunnel, Operation Administration and Maintenance (OAM) / protection, application awareness, and flow detection.

[0076] PoP enables the connection between Virtual Private Cloud (VPC) and Wide Area Network at the tenant level, thus bridging the cloud and network connectivity.

[0077] The SD-WAN controller calculates the overlay path between CPE and PoP, or between CPE and CPE; it obtains the backbone underlay path from the cloud backbone controller according to the business SLA requirements, and concatenates the backbone underlay path and overlay path to send it to CPE to achieve end-to-end connectivity.

[0078] The SD-WAN solution based on SRv6 enables end-to-end Underlay and Overlay collaboration, provides differentiated SLA guarantees, achieves fine-grained service scheduling, and ensures end-to-end network manageability and visibility, thus improving the integrated operation experience. However, the following issues exist:

[0079] Services offering the same service may be deployed on different public clouds or edge clouds. In a multi-cloud scenario, when switching cloud services, the cloud-side resource monitoring system needs to report clouds with poor service capabilities or faulty nodes to the cloud management platform. The cloud management platform then notifies the orchestration system, which finally sends the notification to the Smart WAN controller, which adjusts the destination of the CPE. This results in a lengthy management process, slow cloud service switching, and significant service latency.

[0080] Based on this, in various embodiments of this application, the CPE receives a first message sent by the PoP; wherein the first message carries detection information of each of at least two cloud nodes. Thus, the CPE can perceive the detection information of multiple cloud nodes, thereby understanding the service capabilities of different cloud nodes; when switching cloud services in a multi-cloud scenario, the CPE can select the cloud node providing the cloud service based on the detection information of the cloud nodes, shortening the management process for switching cloud services between cloud nodes, accelerating the switching speed of cloud services, and thereby reducing service latency.

[0081] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0082] This application provides a message processing method applied to a CPE, as described in the embodiments below. Figure 2 The method includes:

[0083] Step 201: Receive the first message sent by PoP.

[0084] The first message carries first information for each of at least two cloud nodes; the first information represents the detection information of the cloud node.

[0085] Here, the first message can be understood as an SRv6 message. At least two cloud nodes are located within an SRv6-based SD-WAN, and these two cloud nodes can provide the user with at least one identical cloud service. A cloud node is a terminal or server of a cloud service provider.

[0086] In one embodiment, the first information of each of the at least two cloud nodes is encapsulated in the first TLV of the SRH of the first message.

[0087] Here, a TLV can be defined in the SRH, and the data field of the TLV can carry the first information of each cloud node in at least two cloud nodes.

[0088] In one embodiment, the first information includes at least one of the following information about the cloud node:

[0089] Network-related performance metrics;

[0090] Service-related performance metrics;

[0091] Availability test results;

[0092] Resource location detection results.

[0093] In practical applications, the first information about network attributes includes network-related performance indicators, which include at least one of the following: network latency, packet loss rate, routing hop count, connection establishment using Transmission Control Protocol (TCP), and network bandwidth.

[0094] The first piece of information about a service attribute includes service-related performance metrics. These performance metrics can differ for different cloud services. For example, performance metrics for a Content Delivery Network (CDN) service include first-packet response time and buffer hit rate; performance metrics for cloud storage services include data upload and download speeds.

[0095] Availability test results characterize whether the cloud services provided by the cloud node are available.

[0096] The resource location detection results of cloud nodes indicate whether there is cross-carrier or cross-regional resource access.

[0097] Specifically, a first TLV can be defined in the "Optional Type Length Value objects" of the SRH, and the data field of the first TLV can carry the first information of each cloud node in at least two cloud nodes.

[0098] The field value of the type field in the first TLV is used to describe the TLV type and can occupy 8 bits.

[0099] In the first TLV, the length field is used to describe the length of the first piece of information. For example, the value of the length field indicates that the length of the first piece of information is 8 bits. It should be noted that the length described by the value of the length field does not include the length of the type field in the first TLV or the length field itself.

[0100] Here, the first piece of information can be understood as OAM information, specifically in-band / In-situ Operation Administration and Maintenance (IOAM) information.

[0101] In practical applications, an "IOAM-Trace-Type" field can be defined in IOAM to indicate which type of primary information the CPE needs to retrieve from the IOAM data space. This primary information includes the four main categories mentioned above: network-related performance metrics, service-related performance metrics, availability detection results, and resource location detection results. Specifically, the "IOAM-Trace-Type" field can be set to different values ​​to instruct the CPE to read the corresponding category of primary information from the IOAM data space. Alternatively, the bit representing the corresponding category can be set to indicate which category of primary information needs to be retrieved.

[0102] For example, such as Figure 3 As shown. For example, when the IOAM-Trace-Type field value is “0001”, the CPE reads network-related performance metrics from “node data list[0]”. When the IOAM-Trace-Type field value is “0010”, the CPE reads service-related performance metrics from “node data list[1]”. When the IOAM-Trace-Type field value is “0011”, the CPE reads network-related performance metrics from “node data list[0]” and service-related performance metrics from “node data list[1]”.

[0103] After receiving the second message sent by the terminal, the CPE encapsulates an IPv6 header around the second message and then sends the encapsulated IPv6 header-encapsulated second message to the PoP. In one embodiment, after receiving the first message sent by the PoP, the method further includes:

[0104] Based on the first information of each of the at least two cloud nodes, the SID of the last hop in the segment list of the second message is changed from the first SID to the second SID; wherein,

[0105] The first SID represents the SID assigned to the user by the first cloud node among the at least two cloud nodes; the second SID represents the SID assigned to the user by the second cloud node among the at least two cloud nodes.

[0106] Here, the CPE receives the second message sent by the terminal. The second message can be understood as an SRv6 message. The destination IP address of the second message points to the first cloud node. Based on the first cloud node pointed to by the second message, the segment list of the second message is determined, and an IPv6 message header is encapsulated in the outer layer of the second message. The IPv6 message header includes the segment list.

[0107] Upon receiving the first message from the PoP, the CPE parses the first information carried in the received message to obtain the detection information of each of the at least two cloud nodes. Based on the detection information of each cloud node, it determines the cloud node that better meets the quality of service requirements (QoS) standards among the at least two cloud nodes; this is the second cloud node that actually provides cloud services to the terminal sending the second message. According to the mapping relationship between cloud nodes and SIDs, it determines the second SID corresponding to the second cloud node, changes the segment identifier SID of the last hop in the segment list of the second message from the first SID to the second SID, and does not modify the destination IP address of the second message. In this way, the terminal is unaware of this and believes that the cloud service is still provided by the first cloud node.

[0108] When the SID in the segment list of the second packet changes, the segment list of the second packet needs to be updated to re-arrange a better network path to the second cloud node. Based on this, in one embodiment, after changing the SID of the last hop in the segment list of the second packet from the first SID to the second SID, the method includes:

[0109] Update the segment list of the second message based on the second SID.

[0110] In practical applications, when a terminal needs to detect whether the cloud node providing cloud services has changed, the CPE needs to notify the terminal to re-encapsulate the second packet according to the IP address of the changed cloud node. Based on this, in one embodiment, before changing the SID of the last hop in the segment list of the second packet from the first SID to the second SID, the method further includes:

[0111] The terminal that sent the second message is notified to re-encapsulate the second message according to the IP address of the second cloud node.

[0112] Here, the CPE instructs the terminal sending the second message to use the IP address of the second cloud node as the destination IP address, and re-encapsulates the second message according to the new destination IP address. In this way, the destination IP address in the second message sent by the CPE points to the second cloud node.

[0113] Before changing the SID of the last hop in the segment list of the second message, the second cloud node needs to be determined. In one embodiment, before changing the SID of the last hop in the segment list of the second message from the first SID to the second SID, the method further includes:

[0114] The second cloud node is determined based on the first and second information of each of the at least two cloud nodes; wherein the second information characterizes the path quality from the CPE to the corresponding cloud node.

[0115] Here, the path quality from CPE to the corresponding cloud node can be either path loss or path cost.

[0116] In practical applications, CPE can determine the first score of the corresponding cloud node based on the first information of each cloud node; where the first information includes at least two of the above categories, the first information of the cloud node can be weighted and summed to obtain the first score.

[0117] Furthermore, the CPE determines the second score of each cloud node based on the second information of that cloud node; it then performs a weighted sum of the first score and the corresponding second score for each cloud node to obtain the third score; and finally, it determines the second cloud node based on the third score of each cloud node. The first score is used to evaluate service quality, and the second score is used to evaluate path cost. In this way, the CPE can comprehensively consider both the service quality and path cost of a cloud node when selecting the second cloud node.

[0118] The second cloud node can be determined by the CPE or by the controller. In one embodiment, determining the second cloud node based on the first and second information of each of the at least two cloud nodes includes:

[0119] Report the first and second information of each of the at least two cloud nodes to the controller;

[0120] Receive the third information returned by the controller; wherein,

[0121] The third information is used to indicate the second cloud node; the second cloud node is determined by the controller based on the information reported by the CPE.

[0122] Here, the CPE reports the first and second information of each cloud node to the controller. Upon receiving the first and second information for each cloud node, the controller determines the second cloud node based on this information and returns third information to the CPE to indicate the second cloud node. The method by which the controller determines the second cloud node is similar to the method used by the CPE, and will not be elaborated here.

[0123] Correspondingly, embodiments of this application provide a message processing method applied to PoP, refer to Figure 4 The method includes:

[0124] Step 401: Send the first message to the CPE.

[0125] The first message carries first information for each of at least two cloud nodes; the first information represents the detection information of the cloud node.

[0126] Here, the PoP obtains the first information of each of the at least two cloud nodes, encapsulates the first information of each of the at least two cloud nodes into a first message, and sends the first message to the CPE.

[0127] In one embodiment, the first information of each of the at least two cloud nodes is encapsulated in the first TLV of the SRH of the first message.

[0128] In one embodiment, before sending the first message to the CPE, the method further includes:

[0129] Receive the first information reported by each of the at least two cloud nodes.

[0130] Here, cloud nodes can detect their own network status, service capabilities, availability, resource location, etc., obtain corresponding detection results, and report the first information to the PoP based on the detection results.

[0131] The Point of Protection (PoP) receives the first information reported by each cloud node. Cloud nodes can report this first information to the PoP through configured plugins. If the PoP has subscribed to the first information, cloud nodes can report it via an Application Programming Interface (API). Cloud nodes can also trigger cloud gateways to report the first information to the PoP according to the detection protocol.

[0132] Availability testing is used to detect whether cloud nodes are available. Since service outages are usually very short-lived and closely related to time periods (e.g., service outages are more likely to occur during peak access times), to ensure the accuracy of availability testing results, it is necessary to conduct long-term real-time monitoring of cloud service availability at a high testing frequency for each time period, and to record long-term availability testing data for users to review.

[0133] Resource location detection primarily involves the location and allocation of cloud services resources. A good resource allocation and location strategy allows users to access the resources and services they need more quickly, while problems with the resource allocation strategy can lead to additional network latency and a decline in service quality. Therefore, cloud nodes can probe cloud services from multiple monitoring points to understand the resource location strategies of each cloud node and whether cross-carrier or cross-regional resource access exists. These monitoring points can be distributed across different geographical locations, correspond to different carriers, and employ different access methods.

[0134] It should be noted that when the PoP receives the first information reported by at least two cloud nodes, the PoP generates the first message based on the first information reported by the at least two cloud nodes.

[0135] For example, when generating the first message, the PoP can set the following based on the category of the first information: Figure 3 The value of the "IOAM-Trace-Type" field is entered, and the first information of the corresponding category is written into the corresponding "node data list".

[0136] In one embodiment, the first information includes at least one of the following information about the cloud node:

[0137] Network-related performance metrics;

[0138] Service-related performance metrics;

[0139] Availability test results;

[0140] Resource location detection results.

[0141] Here, if the cloud node has completed network testing, the first information includes network-related performance metrics of the cloud node. If the cloud node has completed service capability testing, the first information includes service-related performance metrics of the cloud node. If the cloud node has completed availability testing, the first information includes the availability test results of the cloud node. If the cloud node has performed resource location testing, the first information includes the resource location test results of the cloud node.

[0142] Upon receiving a first message from the PoP, the CPE determines, based on the first message, whether to change the SID of the last hop in the segment list of the second message sent by the terminal. If the SID of the last hop in the segment list of the second message is changed, the CPE sends a second message with the updated segment list to the PoP. Accordingly, in one embodiment, the method further includes:

[0143] Receive a second message; wherein the SID of the last hop in the segment list of the second message is configured as the second SID and the destination IP address of the second message points to the first cloud node; the second SID represents the SID assigned to the user by the second cloud node;

[0144] Based on the mapping relationship between the second SID and the second cloud node, the second message is sent.

[0145] Here, the second packet can be sent by the CPE or another PoP. The SID of the last hop in the segment list of the second packet is changed from the first SID to the second SID. Since the CPE does not modify the destination IP address of the second packet, the destination IP address of the second packet still points to the first cloud node.

[0146] The PoP stores the mapping relationship between SID and cloud nodes. When the PoP receives the second message sent by the CPE, it decapsulates the IPv6 header of the second message to obtain the decapsulated second message, the second SID in the IPv6 header of the second message, and the segment list.

[0147] Based on the mapping relationship between SID and cloud node, the Point of Preservation (PoP) determines the second cloud node corresponding to the second SID; based on the mapping relationship between cloud node, egress interface, and Virtual Local Area Network (VLAN), it determines the egress interface and VLAN corresponding to the second cloud node. According to the segment list of the second packet, the PoP determines the network path from the PoP to the second cloud node, forwards the second packet along the determined network path, and finally maps the second packet to the egress interface and VLAN corresponding to the second cloud node.

[0148] Considering that a Point of Presence (PoP) can connect to one cloud node or at least two cloud nodes (i.e., different PoPs connect to different cloud nodes), when a PoP connects to both the first and second cloud nodes, the PoP does not need to modify the network path of the second message; however, if the PoP directly connects to the first cloud node but not directly to the second cloud node, the PoP needs to modify the network path of the second message to send it to the next PoP. Therefore, in one embodiment, before sending the second message, the method further includes:

[0149] Modify the first path based on the IP address of the second cloud node.

[0150] The first path represents the path from the PoP to the second cloud node.

[0151] Here, the second packet obtained by decapsulating the PoP needs to pass through at least one other PoP before reaching the second cloud node. Therefore, based on the connection relationship between the PoP and the cloud node, the PoP determines all the PoPs that must be passed from the PoP to the second cloud node, and modifies the first path according to the determined IP addresses of the PoP and the second cloud node.

[0152] The embodiments of this application will be further described below with reference to the interactive flow diagram.

[0153] Figure 5 The message processing method shown includes:

[0154] Step 1: The terminal sends a second message to the CPE, and the destination IP address in the second message points to the first cloud node.

[0155] Step 2: The CPE receives the second message sent by the terminal and encapsulates an IPv6 header on the outer layer of the second message.

[0156] Step 3: The first cloud node reports its first information to the PoP.

[0157] It should be noted that steps 3 and 4 are parallel steps to step 1.

[0158] In one embodiment, the first information includes at least one of the following information about the cloud node:

[0159] Network-related performance metrics;

[0160] Service-related performance metrics;

[0161] Availability test results;

[0162] Resource location detection results.

[0163] Step 4: The second cloud node reports its first information to the PoP.

[0164] Step 5: The PoP receives the first information reported by at least two cloud nodes.

[0165] Step 6: Based on the received first information, the PoP sends a first message to the CPE; the first message carries the first information of each of the at least two cloud nodes.

[0166] In one embodiment, the first information of each of the at least two cloud nodes is encapsulated in the first TLV of the SRH of the first message.

[0167] Step 7: CPE receives the first message sent by PoP.

[0168] Step 8: Based on the first information of each of the at least two cloud nodes, change the SID of the last hop in the segment list of the second message from the first SID to the second SID.

[0169] Wherein, the first SID represents the SID assigned to the user by the first cloud node among the at least two cloud nodes; the second SID represents the SID assigned to the user by the second cloud node among the at least two cloud nodes.

[0170] In one embodiment, before the CPE changes the SID of the last hop in the segment list of the second message from the first SID to the second SID, the CPE determines the second cloud node based on the first information and the second information of each of the at least two cloud nodes; wherein the second information characterizes the path quality from the CPE to the corresponding cloud node.

[0171] In one embodiment, before the CPE changes the SID of the last hop in the segment list of the second message from the first SID to the second SID, the CPE reports first information and second information of each of the at least two cloud nodes to the controller; and receives third information returned by the controller; wherein the third information is used to indicate the second cloud node; the second cloud node is determined by the controller based on the information reported by the CPE.

[0172] In one embodiment, before the CPE changes the SID of the last hop in the segment list of the second message from the first SID to the second SID, the CPE may also notify the terminal sending the second message to re-encapsulate the second message according to the IP address of the second cloud node.
