Description

Data forwarding method and apparatus based on applied network technology This application claims priority to Chinese Patent Application No. 202411553927.8, filed on November 1, 2024, entitled "Data Forwarding Method and Apparatus Based on Application Network Technology", the entire contents of which are incorporated herein by reference. Technical Field This invention relates to the field of communication technology, and in particular to a data forwarding method and apparatus based on application network technology. Background Technology Tenants have varying Quality of Service (QoS) requirements. For example, real-time audio and video services prioritize QoS, latency, and packet loss rate; while ordinary internet services prioritize cost. Currently, for differentiated service forwarding, multiple physical networks are provided, each offering a different QoS. As shown in Figure 1, three physical networks can be provided: Gold physical network (premium leased line service), Silver physical network (ordinary leased line service), and Copper physical network (Internet service). The Gold physical network provides premium leased line service to Gold tenants (those with high QoS requirements, such as low latency); the Silver physical network provides ordinary leased line service to Silver tenants (those with medium QoS requirements, such as high overall cost-effectiveness); and the Copper physical network provides Internet service to Copper tenants (those with lower QoS requirements, such as low cost). Tenants choose the appropriate differentiated network plane service based on their specific QoS needs. However, building multiple physical networks may result in lower utilization of network resources. Summary of the Invention This invention provides a data forwarding method and apparatus based on application network technology, which divides the physical network into virtual networks with different service quality requirements. This can make full use of the physical network resources, improve the utilization rate of network resources, and adapt to the diverse service quality requirements of users, thereby improving the user experience. In a first aspect, embodiments of the present invention provide a data forwarding method based on application network technology. The method is applied to a first acceleration node, which is deployed in an application network that runs on a physical network. The first acceleration node is connected to a controller. The method includes: Obtain the service attribute table sent by the controller. The service attribute table includes the tenant access identifier and the forwarding plane corresponding to the tenant access identifier. The tenant configuration service quality requirements corresponding to the tenant access identifier are determined based on the service quality requirements. The forwarding plane includes at least some acceleration nodes in the application network. Obtain the data request from the terminal. The data request includes the target tenant access identifier. Determine the target forwarding plane based on the target tenant access identifier and the service attribute table. Send the data request to the second acceleration node in the target forwarding plane. This solution divides the physical network into virtual networks with different quality of service (QoS) requirements. This fully utilizes the physical network resources, improves network resource utilization, and can adapt to diverse user QoS requirements, thus enhancing user experience. Furthermore, by constructing virtual networks based on QoS requirements, the virtual networks are decoupled from the destination addresses. This eliminates the need to continuously expand the virtual networks based on changes in destination addresses, reducing virtual network complexity and minimizing storage resource consumption. In one possible implementation, the target forwarding plane includes a target routing path, which is a path to the second acceleration node. Sending a data request to the second acceleration node in the target forwarding plane includes: Based on the target routing path, forward the data request to the second acceleration node in the target forwarding plane. In one possible implementation, the second acceleration node is used to forward data requests to the destination; sending data requests to the second acceleration node in the target forwarding plane includes: Forward the target routing path and data request to the next acceleration node indicated by the target routing path. In this solution, the first acceleration node determines the unique path for forwarding data requests. Subsequent acceleration nodes do not need to query the business attribute table; they can forward data requests based on the parsed unique path, thereby improving forwarding efficiency. In one possible implementation, before retrieving the forwarding plane routing table sent by the controller, the method further includes: The lin
