Summary

• What is new: Virtuoso, a software network stack, re-organizes the network stack for better CPU utilization, isolation, and reduced overheads.
• Why this is important: Existing layered architecture in VMs and containers cause performance, resource efficiency, and latency issues due to separate network stack instances.
• What the research proposes: Virtuoso implements a shared, elastic network stack instance with central, fine-grained resource accounting and a single-layer data path to minimize processing overheads.
• Results: Improves resource efficiency by up to 82%, reduces latencies by up to 58%, and keeps processing overhead within 6.7% of non-virtualized stacks.
