[0063] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0064] With the development of cloud computing, the scale of hybrid cloud clusters is getting larger and larger, the scale of cloud networks in the cluster is getting larger and larger, and the traffic bandwidth in the cloud network is also getting larger and larger. In actual production, data shows that the computing intranet bandwidth traffic distribution on the host server of the production cloud host is very uneven.

[0065] In the existing cloud network, at the virtual interface on the cloud network, QOS (Quality of Service) and PPS (Packet Per Second) are usually set to regulate the network traffic of the cloud host, so that the network traffic of the cloud host is kept normal and stable to a certain extent. However, the existing regulation method has certain limitations and still has certain risks of causing network congestion and network packet loss and other unstable traffic problems, affecting the accuracy, stability and reliability of the cloud network, so it is difficult to adapt to the high-quality network environment demand of cloud computing on the cloud network.

[0066] Therefore, it is a technical problem to be solved at present to provide a network scheduling method that can improve the accuracy and stability of the cloud network.

[0067] As shown in Figure 1 The first aspect of the embodiment of the present application provides a network scheduling method, which comprises:

[0068] Step S110, obtaining the target traffic bandwidth of the target tenant server.

[0069] Exemplarily, the target traffic bandwidth of the target tenant server at the current time can be determined by obtaining the historical network browsing request of the target tenant server. The target traffic bandwidth of the target tenant server can also be determined according to the traffic subscription information of the target tenant server.

[0070] Exemplarily, the traffic bandwidth information of the target tenant server can be obtained periodically by using network topology perception technology to determine the target traffic bandwidth of the target tenant server.

[0071] Step S120, obtaining the network topology information of the network architecture where the target tenant server is located.

[0072] As shown in Figure 2 The network architecture where the target tenant server is located comprises the target tenant server and the cloud host server, the access layer switch and the core layer switch. The cloud host server forms network communication with the target tenant server through the access layer switch, the core layer switch and the access layer switch in turn.

[0073] Exemplarily, the network topology information of the network architecture where the target tenant server is located can be acquired through a network topology awareness technology, where the network topology awareness technology can include an SNMP (Simple Network Management Protocol) technology.

[0074] In step S130, a traffic transmission path of the target tenant server is determined based on the target traffic bandwidth and the network topology information.

[0075] Exemplarily, the network devices can be converted into a logical topology structure through the network topology awareness technology, so that the traffic transmission path can be determined according to the logical topology structure.

[0076] Exemplarily, 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 the network devices in the network architecture.

[0077] In step S140, the target cloud host server is determined according to the traffic transmission path.

[0078] Exemplarily, the target cloud host server can be determined according to the length of the traffic transmission path. The target cloud host server can also be determined according to the transmission rate of the network devices on the traffic transmission path.

[0079] In step S150, the target tenant server is controlled to access the target cloud host server.

[0080] The network scheduling method provided by the embodiments of the present application can acquire the target traffic bandwidth of the target tenant server and the network topology information in the network architecture where the target tenant server is located. The target tenant server can be accessed by the target cloud host server that can establish a communication connection with the target tenant server through the network devices in the network architecture, according to the network topology information of the target traffic bandwidth in the network architecture where the target tenant server is located, so that the network transmission rate in the network architecture where the target tenant server is located can meet the target traffic bandwidth required by the target tenant server. The cloud network can be scheduled in real time according to the target traffic bandwidth required by the target tenant server, the bandwidth allocation quality of the cloud host network can be improved based on the traffic transmission path, the transmission speed of the cloud network can be improved, and the accuracy, stability and reliability of the cloud network can be further improved, so that the network performance of the cloud network can be improved.

[0081] In some possible implementations, the network topology information includes at least one of IP routing information of the network devices in the network architecture, an ingress interface rate of the cloud host servers in the network architecture, an egress interface rate of the cloud host servers, an IP address of the cloud host servers and an IP address of the target tenant server.

[0082] Exemplarily, the network devices in the network architecture can be converted into a logical topology structure by a network topology awareness technology. The sending bandwidth rate and the receiving bandwidth rate of each link interface and the IP routing information table of each network device in the network architecture can be obtained in the logical topology structure.

[0083] As shown in Figure 3 The network architecture includes an access layer switch entity and a core layer switch entity. As shown in Figure 4 The network device entity in the network architecture can be converted into a logical topology structure. It can be seen that there can be multiple traffic transmission paths between the same target cloud host server and the same target tenant server for establishing network connection.

[0084] As shown in Figure 4 It can be seen that the L1 switch is used as the switching starting point for accessing the switching traffic, and the Ln switch is used as the switching end point for connecting the target tenant server, and three traffic transmission paths can be obtained. Specifically, it can include: the first traffic transmission path: the L1 switch establishes network communication with the S1 switch through the sub-path 1, and the S1 switch establishes network communication with the Ln switch through the sub-path 3. The second traffic transmission path: the L1 switch establishes network communication with the Sn switch through the sub-path 2, and the Sn switch establishes network communication with the Ln switch through the sub-path 4. The third traffic transmission path: the L1 switch establishes network communication with the S1 switch through the sub-path 1, and the S1 switch establishes network communication with the Sn switch through the sub-path 5, and the Sn switch establishes network communication with the Ln switch through the sub-path 4.

[0085] The network scheduling method provided by the embodiment of the application can increase the comprehensiveness and diversity of network topology information, further facilitate the determination of the traffic transmission path according to the network topology information, reduce the difficulty of determining the traffic transmission path, and improve the objectivity of the network scheduling method. Thus, the real-time and timeliness of the network scheduling method for cloud network bandwidth scheduling can be further improved, the bandwidth allocation quality of the cloud host network can be improved, the transmission speed of the cloud network can be improved, the accuracy, stability and reliability of the cloud network can be further improved, and thus the network performance of the cloud network can be improved.

[0086] In some possible implementation manners, the traffic transmission path of the target tenant server is determined based on the target traffic bandwidth and the network topology information, including: determining at least one first cloud host server according to the target traffic bandwidth and the network topology information, where an 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 according to the network topology information; and determining the target cloud host server according to 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 a length of the traffic transmission path.

[0087] Exemplarily, the traffic transmission path between each first cloud host server and the target tenant server can be determined according to a Dijkstra shortest path priority algorithm.

[0088] The network scheduling method provided by the embodiment of the present application can filter all cloud host servers in the network architecture where the target tenant server is located by using the outgoing interface rate related to the traffic transmission of the cloud host server in the network topology information, so as to obtain at least one first cloud host server that can meet the target traffic bandwidth requirement of the target tenant server, and can guarantee the network access quality and bandwidth requirement of the target tenant server. Further, 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. Therefore, the transmission speed of the cloud network can be improved, and further, the accuracy, stability and reliability of the cloud network can be improved, so that the network performance of the cloud network can be improved.

[0089] In some possible implementation manners, before the step of controlling the target tenant server to access the target cloud host server, the method further includes: obtaining an initial cloud host server currently accessed by the target tenant server; determining, according to the network topology information, whether the initial cloud host server and the target cloud host server exist connection; and controlling the target tenant server to access the target cloud host server, including: in the case that the initial cloud host server and the target cloud host server exist connection, controlling the target tenant server to be hot migrated from the initial cloud host server to the target cloud host server.

[0090] As shown in FIG. 1, Figure 5 The initial cloud host server accessed by the target tenant server establishes network communication with 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.

[0091] As shown in FIG. 1, Figure 6As shown, the target cloud host server accessed by the target tenant server 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.

[0092] It can be seen that the traffic transmission path between the target cloud host server and the target tenant server is obviously smaller than the traffic transmission path between the initial cloud host server and the target tenant server.

[0093] Exemplarily, in the hot migration operation, the problem of target cloud host server migration failure can occur. In the case of hot migration failure, the resource margin of the target cloud host server needs to be called. In the case of insufficient resource margin of the target cloud host server, the target cloud host server can be marked first, and then a timer is enabled until the hot migration of the target cloud host server is performed after the timer expires.

[0094] The network scheduling method provided by the embodiment of the present application can determine whether the hot migration between the initial cloud host server and the target cloud host server can be performed according to the connection relationship between the initial cloud host server and the target cloud host server, which can further improve the accuracy of the network scheduling method, avoid the problem of network disconnection of the target tenant server, improve the bandwidth allocation quality of the cloud host network, improve the fluency and stability of the target tenant server, 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.

[0095] In some possible implementation manners, the network scheduling method further includes: in the case that the initial cloud host server and the target cloud host server do not exist connection, determining at least one second cloud host server that exists connection with the initial cloud host server; and determining the second cloud host server with the shortest traffic transmission path as a target secondary cloud host server according to the target traffic bandwidth and the network topology information.

[0096] The network scheduling method provided by the embodiment of the present application can ensure that the target secondary cloud host server can realize hot migration with the initial cloud host server, thereby improving the fluency and stability of the target tenant server network, and at the same time, the bandwidth and traffic transmission path of the target secondary cloud host server can also be considered, which can further meet the traffic bandwidth demand of the target tenant server, shorten the length of the traffic transmission path, improve the network transmission speed, improve the bandwidth allocation quality of the cloud host network, and further improve the accuracy, stability and reliability of the cloud network, thereby improving the network performance of the cloud network.

[0097] In some possible implementation manners, the network scheduling method further includes: controlling the target tenant server to be hot migrated from the initial cloud host server to the target secondary cloud host server.

[0098] The network scheduling method provided by the embodiments of the present application can improve the fluency and stability of the network of the target tenant server, improve the network transmission speed, improve the bandwidth allocation quality of the cloud host network, and further improve the accuracy, stability and reliability of the cloud network, so that the network performance of the cloud network can be improved.
