[0192] In order to make the technical problems, technical solutions and advantages to be solved by this application clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0193] The following first introduces the relevant contents of this plan.

[0194] Nowadays, more and more streaming media and real-time interactive applications have become the mainstream traffic of the Internet and cloud networks; for example, multi-person real-time video conferencing applications, real-time live shopping applications, etc. The services of these applications are growing because the videos are becoming more and more high-definition, the number of people served is increasing, and the real-time traffic is also growing; therefore, during peak hours, there will be bursts of traffic on some networks, which will cause congestion, packet loss and service quality degradation. In order to optimize the service experience, the optimization method from the transport layer and application layer is to use the QUIC (Quick UDP (User Datagram Protocol) Internet Connection) protocol instead of the TCP (Transmission Control Protocol) protocol. The QUIC protocol has the advantages of 0-RTT (zero round-trip time) to establish connections, no head-to-head blocking, and connection migration. It can optimize the business experience to a certain extent, but it cannot eliminate the performance loss caused by the intermediate transmission network. In this regard, the solution currently proposed is to use a detour in the overlay cloud network (for example Figure 1 As shown in the figure, by designing a cost function, the link with the lowest cost and meeting business needs can be flexibly selected from the dedicated line and Internet (network) links. Figure 1 The solution shown can use the cloud management platform (cloud network controller) to select the Internet or dedicated line, and perform operations such as scaling the proxy container (based on prediction information); Figure 1 Pa represents the proxy container.

[0195] exist Figure 1In this example, Client_1 and Client_2 are participating in the same video conferencing service. They can see each other's video and hear each other's audio. In a real-world network, Client_1 and Client_2 are not directly connected, but rather through a complex network consisting of the Internet access network, overlay cloud networks, and intermediate proxies. Client_1 and Client_2 can establish QUIC connections with proxies in Regions A and C, respectively. These proxies are available as containers and are destroyed and recycled after the service ends. When proxies in Regions A and B communicate, they do so over dedicated lines or the Internet. The Internet is inexpensive, but its quality cannot be guaranteed during peak service times, and the cloud network cannot access Internet information. Dedicated lines offer good quality but are expensive. To address this, the cloud network controller (corresponding to the cloud management platform) pre-designs a prediction model based on traffic statistics, container usage, and other factors. It also configures a backup path based on a comprehensive cost function and distributes flow table information for both the primary and backup paths to the data plane. When the data plane quality deteriorates, the data plane can automatically select a backup path in a distributed manner and forward data via a detour. During this process, a dedicated line can be selected. Since the billing method is based on traffic rather than bandwidth, the detour path cost can also meet the requirements during the meeting time.

[0252] Region proxy node D forwards the marked QUIC stream to Region proxy node C; corresponding to the above-mentioned target proxy node, based on the third information, sends the first data stream to the first proxy node through the second network connection.

[0253] Region proxy node C replaces the corresponding data stream of (Region) proxy node A with the data stream sent by (Region) proxy node D; specifically, Region C proxy node identifies the tag number of the QUIC stream, replaces the existing transmission data stream from Region A to Region C with the data stream transmitted from Region D, and uses the original transmission channel to Client_2 to forward the data stream; it can correspond to the above-mentioned first proxy node receiving the first data stream sent by the target proxy node through the second network connection according to the third information; the first data stream carries a target identifier, and the target identifier is the same as the network connection flow identifier sent by the first terminal to the source proxy node; sends the first data stream to the second terminal, and stops forwarding the second data stream sent by the source proxy node, and the network connection flow identifier is carried in the second data stream.

[0254] Region proxy node C notifies Region proxy node A (migration source, corresponding to the above-mentioned source proxy node) of the connection interruption; it can correspond to the above-mentioned first proxy node receiving the first identification information of the first network connection sent by the first network device; the first network connection refers to the network connection between the first terminal and the source proxy node; according to the first identification information, after sending the first data stream to the second terminal, a connection interruption indication is sent to the source proxy node, and the connection interruption indication is used to indicate the interruption of the first network connection.

[0255] Region proxy node A notifies Client_1 of the connection interruption; this may correspond to the above-mentioned source proxy node receiving a connection interruption indication sent by the first proxy node, where the connection interruption indication is used to indicate the interruption of the first network connection; the first proxy node is a proxy node connected to the second terminal, and the second terminal is in the same service as the first terminal; according to the connection interruption indication, the first network connection is interrupted; and the connection interruption indication is sent to the first terminal.

[0256] Client_1 can interrupt the corresponding connection according to the notification sent by Region proxy node A; it can correspond to the connection interruption indication sent by the source proxy node received by the above-mentioned first terminal, and the connection interruption indication is used to indicate the interruption of the first network connection; the first network connection refers to the network connection between the first terminal and the source proxy node; according to the connection interruption indication, the first network connection is interrupted.

[0257] based on Figure 9 The operations shown in this figure can be implemented as follows:

[0258] against Figure 8Framework, Client_1 establishes a QUIC connection with the proxy node (proxy container) of Region A (obtaining the corresponding four-tuple information (source address, source port, destination address, destination port) and the connection unique identification number connection ID_1), Client_2 establishes a (QUIC) connection with the proxy node of Region C, and the proxy node of Region A establishes a QUIC connection with the proxy node of Region C (obtaining the corresponding four-tuple information (source address, source port, destination address, destination port) and the connection unique identification number connection ID_0), end-to-end connection is pulled together, and the service is started. At this time, the proxy node of RegionA will report the four-tuple information (source address, source port, destination address, destination port) related to the QUIC connection of client_1 and the connection unique identification number connection ID_1 (corresponding to the first identification information of the first network connection sent to the first network device mentioned above) to the cloud management platform. The cloud management platform will synchronize all Region-related location information (including gateway addresses) to the network controller (corresponding to the node information of the proxy node under the target coverage range sent to the second network device above), and the network controller will feedback Client_1's access network information to different reachable Regions (corresponding to the first access network information sent to the first network device above), wherein the access network information may include at least one of the following information: latency information, link bandwidth information, network link type (such as dedicated line or Internet); in this solution, the network controller may also feedback access network information of different Regions that are unreachable to Client_1; this is not limited here. Among them, the proxy node of Region A above corresponds to Figure 9 The proxy node of Region A and the proxy node of Region C correspond to Figure 9 Region proxy node C in.

[0259] To prevent the impact of sudden data plane traffic on end-to-end links, the cloud management platform can pre-integrate the compute capacity of each region proxy node (corresponding to the aforementioned proxy node compute capacity information, which may include the compute capacity of all region proxy nodes within the cloud management scope and is independently accessible to the cloud management platform), access network quality (corresponding to the aforementioned access network information), and network conditions between region proxy nodes (corresponding to the aforementioned inter-proxy network quality information and is independently accessible to the cloud management platform) to determine the region proxy node to be migrated (i.e., the target proxy node). The calculation details are internal to the cloud management platform and can be implemented in various ways. Specifically, for example, a comprehensive cost function can be designed to calculate a comprehensive cost based on information such as the compute capacity of the region proxy node, path delay (an example parameter of access network quality, which can be obtained from delay information), and path charging rules. The path and region proxy node with the lowest comprehensive cost can then be determined. A prediction model can be constructed based on statistical information such as the compute capacity of the region proxy node and path delay to determine the performance of each region proxy node and path in the next time period and assign weights (i.e., to obtain the corresponding comprehensive cost).

[0260] For example, an optional calculation method defines a comprehensive cost function Cost. Assuming that the computation capacity cost value is C_cap, the path delay cost value is C_path, and the path charging cost value is C_val, the comprehensive cost function is:

[0261] Cost = C_cap + C_path + C_val;

[0262] Based on the above, you can select the region proxy node with the lowest cost value as the region proxy node to be migrated, that is, the migration destination region proxy node.

[0263] After obtaining the migration destination Region proxy node (i.e., Region proxy node D), the cloud management platform can send connection ID_1 and the corresponding quadruple information to the proxy node of Region D (corresponding Figure 9 Region proxy node D) and Region C proxy node connected to client2 (corresponding to Figure 9In this solution, the cloud management platform may also send the identity information of the proxy node in Region C to the proxy node in Region D, and / or the cloud management platform may also send the identity information of the proxy node in Region D to the proxy node in Region C, so that the proxy node in Region C can establish a connection with the proxy node in Region D. After the proxy node in Region C receives the connection ID_1 and corresponding quadruple information sent by the cloud management platform, it can be used to subsequently disconnect related network connections and assist in identifying the "QUIC stream tag number" to assist in replacing related data streams, but the invention is not limited to this.

[0264] Then, the migration destination Region agent node and the data receiving end (i.e. Figure 8 The migration destination Region proxy node establishes a QUIC connection with the Region (i.e., Region C) proxy node connected to the client_2 in the migration destination, such as the video receiving end (obtaining the corresponding four-tuple information (source address, source port, destination address, destination port) and the connection unique identification number connection ID_2), corresponding to the above-mentioned establishment of a second network connection with the first proxy node, and obtains third information; the third information includes: the second identification information of the second network connection; in order to ensure service continuity, the migration destination Region proxy node does not send data immediately after the connection with the Region C proxy node is established. The Region C proxy node performs waiting processing and performs alternative processing after officially receiving the data stream.

[0265] The proxy node of the migration destination Region (i.e., Region D) then initiates a connection migration request to Client_1. After receiving the connection migration request, Client_1 can feedback a connection migration response, and client_1 establishes a new QUIC connection with the Region D proxy node (migration destination) (obtaining a unique connection number connection ID_3, and the corresponding four tuple information four tuple_3). Client_1 sends a data stream to the Region D proxy node through the established connection, and marks the QUIC stream in the data stream. The tag number used is consistent with the QUIC stream tag number sent by client_1 to the Region A proxy node, which means that the content sent is consistent. Corresponding to the above-mentioned first terminal receiving the connection migration request sent by the target proxy node; sending a connection migration response to the target proxy node, and establishing a third network connection with the target proxy node to obtain fourth information; the fourth information includes: the third identification information of the third network connection; according to the fourth information, sending a first data stream to the target proxy node through the third network connection; the first data stream carries a target identifier, and the target identifier is the same as the network connection stream identifier sent by the first terminal to the source proxy node.

[0266] After receiving the data stream, the Region D proxy node forwards the marked QUIC stream data stream to the Region C proxy node. The Region C proxy node identifies the QUIC stream tag number and replaces the existing transmission data stream from the Region A proxy node to the Region C proxy node with the data stream from the Region D proxy node, and forwards the data stream using the original transmission channel to client_2. Correspondingly, the first proxy node receives the first data stream sent by the target proxy node through the second network connection based on the third information. The first data stream carries a target identifier, which is the same as the network connection flow identifier sent by the first terminal to the source proxy node. The first data stream is sent to the second terminal and the forwarding of the second data stream sent by the source proxy node is stopped. The network connection flow identifier is carried in the second data stream. In this way, end-to-end connection migration from client_1 to client_2 can be achieved without any service perception.

[0267] This achieves end-to-end connectivity. The receiving end, client_2, can seamlessly receive data from client_1. This also allows for flexible migration of services to intermediate proxy nodes (i.e., Region proxy nodes), ensuring end-to-end service quality and enabling low-cost operations for computing and network services.

[0268] It is explained here that the information interaction between the network controller and the cloud management platform can be transmitted through the service interface between the network controller and the cloud management platform, which is not specifically limited here.

[0269] Based on the above, the solutions provided in the embodiments of this application involve the following contents:

[0270] 1. Defines an end-to-end optimized routing method that comprehensively considers multiple dimensions, including network link type (which may include access network link type and inter-region link type, such as dedicated lines or the Internet), link quality (such as latency and bandwidth), cloud service node computing capacity (i.e., region proxy node computing capacity), and billing rules (i.e., the aforementioned path billing rules). This method ensures end-to-end service quality at a low cost. The sending end directs traffic to the migration destination region proxy node, which then establishes a new connection with the region proxy node connected to the receiving end. The region proxy node connected to the receiving end then completes the traffic guidance, ensuring uninterrupted service and a consistent experience for the receiving end.

[0271] Among them, regarding path selection, a comprehensive cost function design is provided: the optimal path is calculated using the comprehensive cost function, specifically considering factors such as computing capacity, path delay, and path billing, so as to select the best Region proxy node and path under different network conditions.

[0272] 2. Defines a method for interaction between the cloud management platform, network controller, and Region proxy node, including specific interaction processes and content. Figure 9 In the process shown, the cloud management platform can first notify the network controller of the gateway address information of each Region A proxy node; the network controller can then provide the cloud management platform with access network information (including latency, link bandwidth, and network link type (dedicated line or Internet)) of the Region A proxy nodes reachable by the terminal. After the cloud management platform determines the migration destination region based on the access network information, it notifies the migration destination region of client_1's QUIC connection Connection ID_1 and four-tuple information. The four-tuple information may include the source address, destination address, source port, and destination port of the QUIC connection between client_1 and the Region A proxy node.

[0273] 3. A QUIC connection migration method for intermediate proxy nodes is defined. The connection migration request can be initiated by the destination proxy node (such as the Region D proxy node mentioned above), that is, the server initiates the connection migration. This method can be used for connection migration of intermediate proxy nodes in multi-terminal interactive video applications to achieve end-to-end routing optimization while ensuring service uninterrupted. Specifically: After determining the optimal access path, the user session can be migrated to the proxy container of the Region D proxy node, achieving end-to-end connection migration to adapt to changes in network quality.

[0274] In summary, this solution has the following beneficial effects compared to existing solutions:

[0275] 1. This route selection comprehensively considers the Internet access situation, the overlay cloud network situation (i.e., the network situation between the aforementioned intermediate proxy nodes), and the region computing capacity. This can achieve end-to-end optimization and is more comprehensive than existing solutions.

[0276] 2. The implementation mechanism of QUIC connection migration has been optimized to avoid the problem of strong binding between users and Region proxy nodes in the existing solution, and scheduling is more flexible.

[0277] It should be noted that this solution can be applied to interactive video applications, such as multi-person video conferencing, live shopping, and other scenarios, and has a wide range of application scenarios now and in the future.
