UDP Message Distribution Using eBPF-Isolated Process Groups

The patent segments the file descriptor management by creating independent EBPF resources for each process group. Each process group has its own dedicated file descriptors and socket buffers, preventing cross-contamination of UDP messages between old and new process groups during upgrades. This segmentation ensures that messages are reliably routed to the correct process group while maintaining service continuity.

The patent introduces an intermediary mechanism (EBPF resource management layer) that sits between the UDP message reception and process group handling. This intermediary maintains a mapping between socket buffers and specific process groups, ensuring messages are correctly routed even when multiple process groups coexist during upgrades, thus resolving the reliability issue while preserving adaptability.

The patent creates a universal EBPF resource management framework that handles multiple process groups through a standardized interface. The same EBPF infrastructure and resource allocation mechanisms are reused across all process groups, providing reliable message distribution without proportionally increasing complexity. The system manages file descriptors and socket buffers uniformly for both old and new process groups.

The patent manages complexity by dynamically allocating EBPF resources based on process group state. When process groups are created or destroyed during upgrades, the system adjusts the number and configuration of EBPF resources accordingly. This parameter-based resource management ensures reliability while adapting the level of complexity to actual operational needs rather than maintaining fixed high complexity.
