[0069] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0070] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0071] With the development of cloud computing, hybrid cloud clusters are becoming increasingly larger, as are the cloud networks within these clusters and the bandwidth of those networks. Real-world production data shows that the distribution of computing network bandwidth traffic on the host servers of production cloud machines is highly uneven.

[0072] In existing cloud networks, QoS (Quality of Service) and PPS (Packets Per Second) are typically configured at virtual interfaces to regulate network traffic on cloud hosts, ensuring a certain degree of normal and stable network traffic. However, existing methods have limitations and still carry the risk of network congestion and packet loss, affecting the accuracy, stability, and reliability of the cloud network. Consequently, they are ill-suited to the high-quality network environment requirements of cloud computing.

[0073] Therefore, providing a network scheduling method that can improve the accuracy and stability of cloud networks is a technical problem that urgently needs to be solved.

[0074] As shown in Figure 1, a first aspect of this application provides a network scheduling method, including:

[0075] Step S110: Obtain the target traffic bandwidth of the target tenant server.

[0076] For example, the target bandwidth of the target tenant server at the current moment can be determined by obtaining the historical web browsing requests of the target tenant server. Alternatively, the target bandwidth of the target tenant server can be determined based on the traffic subscription information of the target tenant server.

[0077] For example, network topology awareness technology can be used to periodically obtain the traffic bandwidth information of the target tenant server in order to determine the target traffic bandwidth of the target tenant server.

[0078] Step S120: Obtain the network topology information of the network architecture where the target tenant server is located.

[0079] As shown in Figure 2, the network architecture of the target tenant server includes the target tenant server, the cloud host server, access layer switches, and core layer switches. The cloud host server communicates with the target tenant server sequentially through the access layer switches, core layer switches, and then access layer switches.

[0080] For example, network topology information of the network architecture in which the target tenant server is located can be obtained through network topology awareness technology, which may include SNMP (Simple Network Management Protocol) technology.

[0081] Step S130: Based on the target traffic bandwidth and network topology information, determine the traffic transmission path of the target tenant server.

[0082] For example, network topology awareness technology can be used to transform network devices into logical topology structures, thereby determining traffic transmission paths based on the logical topology structures.

[0083] For example, the traffic transmission path includes all communication paths between any cloud host server and the target tenant server that can establish network communication with the target tenant server through network devices in the network architecture.

[0084] Step S140: Determine the target cloud host server based on the traffic transmission path.

[0085] For example, the target cloud server can be determined based on the length of the traffic transmission path. Alternatively, the target cloud server can be determined based on the transmission rate of the network devices along the traffic transmission path.

[0086] Step S150: Control the target tenant server to access the target cloud host server.

[0087] The network scheduling method provided in this application obtains the target traffic bandwidth of the target tenant server and the network topology information within the network architecture where the target tenant server is located. This facilitates matching the network transmission rate within the network architecture where the target tenant server is located to meet the target traffic bandwidth requirements of the target tenant server, based on the network topology information. Simultaneously, it connects the target tenant server to a target cloud host server through network devices within the network architecture. Therefore, real-time bandwidth scheduling of the cloud network can be performed based on the target traffic bandwidth required by the target tenant server, improving the bandwidth allocation quality of the cloud host network based on the traffic transmission path, increasing the transmission speed of the cloud network, and further improving the accuracy, stability, and reliability of the cloud network, thereby enhancing the network performance of the cloud network.

[0088] In some feasible implementations, network topology information includes at least one of the following: IP routing information of network devices within the network architecture, inbound interface rate of cloud host servers within the network architecture, outbound interface rate of cloud host servers, IP address of cloud host servers, and IP address of target tenant servers.

[0089] For example, network topology awareness technology can be used to transform network devices within a network architecture into a logical topology. Within this logical topology, the transmit and receive bandwidth rates of each link interface, as well as the IP routing information table of each network device within the network architecture, can be obtained.

[0090] As shown in Figure 3, the network architecture includes access layer switch entities and core layer switch entities. As shown in Figure 4, the network device entities within the network architecture can be converted into a logical topology. It can be seen that multiple traffic transmission paths can be used to establish network connections between the same target cloud host server and the same target tenant server.

[0091] As shown in Figure 4, it can be seen that with switch L1 as the switching origin for incoming traffic and switch Ln as the switching destination for connecting to the target tenant server, three traffic transmission paths can be obtained. Specifically, these can include: First traffic transmission path: Switch L1 establishes network communication with switch S1 through sub-path 1, and switch S1 establishes network communication with switch Ln through sub-path 3. Second traffic transmission path: Switch L1 establishes network communication with switch Sn through sub-path 2, and switch Sn establishes network communication with switch Ln through sub-path 4. Third traffic transmission path: Switch L1 establishes network communication with switch S1 through sub-path 1, switch S1 establishes network communication with switch Sn through sub-path 5, and switch Sn establishes network communication with switch Ln through sub-path 4.

[0092] The network scheduling method provided in this application can increase the comprehensiveness and diversity of network topology information, further facilitating the determination of traffic transmission paths based on network topology information, reducing the difficulty of determining traffic transmission paths, and improving the objectivity of the network scheduling method. This can further improve the real-time and timely nature of cloud network bandwidth scheduling, improve the bandwidth allocation quality of cloud host networks, increase cloud network transmission speed, and further improve the accuracy, stability, and reliability of cloud networks, thereby enhancing cloud network performance.

[0093] In some feasible implementations, determining the traffic transmission path of the target tenant server based on the target traffic bandwidth and network topology information includes: determining at least one first cloud host server based on the target traffic bandwidth and network topology information, wherein the outgoing interface rate of the first cloud host server is greater than or equal to the target traffic bandwidth; determining the traffic transmission path of the first cloud host server based on the network topology information; and determining the target cloud host server based on the traffic transmission path, including: determining the first cloud host server corresponding to the shortest traffic transmission path as the target cloud host server based on the length of the traffic transmission path.

[0094] For example, the traffic transmission path between each first cloud host server and the target tenant server can be determined according to Dijkstra's shortest path first algorithm.

[0095] The network scheduling method provided in this application, by filtering all cloud host servers within the network architecture where the target tenant server is located based on the outgoing interface rate related to traffic transmission of the cloud host server in the network topology information, can obtain at least one first cloud host server that can meet the target traffic bandwidth requirements of the target tenant server, thus ensuring the network access quality and bandwidth requirements of the target tenant server. Furthermore, by determining the first cloud host server corresponding to the shortest traffic transmission path as the target cloud host server, the network communication speed between the target cloud host server and the target tenant server can be improved, the network access quality of the target tenant server can be improved, and the bandwidth allocation quality of the cloud host network can be improved. This can improve the transmission speed of the cloud network, and further improve the accuracy, stability, and reliability of the cloud network, thereby improving the network performance of the cloud network.

[0096] In some feasible implementations, before the step of controlling the target tenant server to access the target cloud host server, the method further includes: obtaining the initial cloud host server currently accessed by the target tenant server; determining whether there is a connection between the initial cloud host server and the target cloud host server based on network topology information; and controlling the target tenant server to access the target cloud host server, including: if there is a connection between the initial cloud host server and the target cloud host server, controlling the target tenant server to hot migrate from the initial cloud host server to the target cloud host server.

[0097] As shown in Figure 5, the target tenant server establishes network communication with the initial cloud host server connected to the L1 switch, the L1 switch establishes network communication with the S2 switch, the S2 switch establishes network communication with the Sn switch, and the Sn switch establishes network communication with the Ln switch.

[0098] As shown in Figure 6, the target tenant server connects to the target cloud host server and establishes network communication with the L2 switch, the L2 switch establishes network communication with the Sn switch, and the Sn switch establishes network communication with the Ln switch.

[0099] It can be seen that the traffic transmission path between the target cloud host server and the target tenant server is significantly shorter than the traffic transmission path between the initial cloud host server and the target tenant server.

[0100] For example, during a hot migration operation, the target cloud server may fail to migrate. In the event of a hot migration failure, it is necessary to utilize the remaining resources of the target cloud server. If the target cloud server has insufficient resources, the target cloud server can be marked first, and then a timer can be started. The hot migration of the target cloud server can only be performed after the timer expires.

[0101] The network scheduling method provided in this application determines whether hot migration can be performed between the initial cloud host server and the target cloud host server based on the connection relationship between them. This can further improve the accuracy of the network scheduling method, avoid network outages for the target tenant server, improve the bandwidth allocation quality of the cloud host network, enhance the smoothness and stability of the target tenant server, increase the transmission speed of the cloud network, and further improve the accuracy, stability, and reliability of the cloud network, thereby improving the network performance of the cloud network.

[0102] In some feasible implementations, the network scheduling method further includes: in the case that there is no connection between the initial cloud host server and the target cloud host server, determining at least one second cloud host server that is connected to the initial cloud host server; and determining the second cloud host server with the shortest traffic transmission path as the target secondary cloud host server based on the target traffic bandwidth and network topology information.

[0103] The network scheduling method provided in this application embodiment can ensure that the target secondary cloud host server can achieve hot migration with the initial cloud host server, thereby improving the smoothness and stability of the target tenant server network. At the same time, it can also take into account the bandwidth and traffic transmission path of the target secondary cloud host server, further meeting the traffic bandwidth requirements of the target tenant server, shortening the length of the traffic transmission path, improving network transmission speed, improving the bandwidth allocation quality of the cloud host network, and further improving the accuracy, stability and reliability of the cloud network, thereby improving the network performance of the cloud network.

[0104] In some feasible implementations, the network scheduling method further includes: controlling the target tenant server to hot migrate from the initial cloud host server to the target secondary cloud host server.

[0105] The network scheduling method provided in this application improves the smoothness and stability of the target tenant server network, increases network transmission speed, and enhances the bandwidth allocation quality of the cloud host network by hot-migrating the target tenant server from the initial cloud host server to the target secondary cloud host server. Furthermore, it can improve the accuracy, stability, and reliability of the cloud network, thereby improving the network performance of the cloud network.
