QUIC restarts, slow problems: udpgrm to the rescue
udpgrm is a lightweight daemon designed for seamless UDP server restarts, utilizing SO_REUSEPORT and eBPF for efficient flow routing.
MAIN POINTS
- udpgrm enables graceful restarts of UDP servers.
- It uses SO_REUSEPORT for port reuse across server instances.
- eBPF is employed to manage flow routing effectively.
- Ensures new and existing flows reach the correct server instance.
TAKEAWAYS
- udpgrm facilitates uninterrupted UDP server operations during restarts.
- SO_REUSEPORT allows multiple server instances to share the same port.
- eBPF provides advanced packet filtering and routing capabilities.
- The daemon enhances server reliability and performance during updates.
