Title:
DATA PROCESSING METHOD AND APPARATUS BASED ON POLICY-BASED ROUTING, DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/093478
Kind Code:
A1
Abstract:
The present application relates to the technical field of communications. Provided are a data processing method and apparatus based on policy-based routing, a device and a non-volatile readable storage medium. The method comprises: on the basis of the kernel data structure of an extended Berkeley Packet Filter (eBPF), configuring policy-based routing; intercepting a data packet required to be sent out, said data packet comprising: a destination address and a plurality of routing rules; determining from amongst a plurality of routing tables a target routing table matched with the routing rules of said data packet; on the basis of a BPF routing lookup function, searching the target routing table for a target network interface card corresponding to the destination address of said data packet; and, by means of a BPF data packet sending function, sending out said data packet on the basis of the target network interface card. In the present application, the policy-based routing is implemented by the eBPF and bypasses Netfilters and some kernel protocol stacks, thus reducing changes to the kernels and processing paths of data packets, realizing highly efficient policy-based routing, improving the network performance, and reducing the development cost and the maintenance cost.
