报告摘要 (Abstract)：

Communication networks are rapidly evolving towards soflware-based architectures, driven by Network Function Virtualization (NFV) and cloud-based netvorking. This talk highlights key lessons from our recent work on high-performance NFV platforms, like OpenNetVM, which underpin our L25GC + 5G core. It significantly reduces latency and enhances data packet processing by rethinking protocol implementation, achieving a 50% improvement in control plane operations and doubling dataplane performance during critical events. In the realm of cloud computing, serverless architectures are gaining traction, yet they often overlook networking eflicieney. We leverage event-driven shared memory and eBPF to streamline networking, eliminating overheads and improving throughput and latency by an order of magnitude compared to existing solutions like Knative, all while reducing CPU usage and mitigating cold-start issues.
