Dynamic Data Plane Updates using Lua and libmoon
Year: 2025
Type: article
Abstract: Upcoming communication networks, such as 6G, require both high performance and reliability, while service updates typically introduce service downtimes. This study explores dynamic network function updates using libmoon, a DPDK-based high-performance packet processing framework. The approach enables seamless, on-the-fly updates of network functions. By leveraging LuaJIT, we profit from just-in-time (JIT) compilation, allowing for efficient per-flow function updates. Our evaluation demonstrates the feasibility of runtime re-programmability in network data planes. We show the induced latencies of runtime changes and examine cross-flow and cross-core influences. Moreover, we investigate the effects of JIT compilation and show the significance of JIT compilation for long-term performance.
