AI 中文摘要
量子互联网基于纠缠运行，纠缠是一种非局域、不可复制、有状态的网络资源，这推动了超越经典分层架构的协议组织方式。我们提出了超越分层协议套件中Dynamic Kernel/QPacket逻辑的首个可执行专用实现，针对线性量子中继器链上的纠缠分发场景。该实现基于Q2NS，这是一个基于ns-3的量子网络仿真模块，可通过ns-3应用商店获取。它实现了带有服务意图的QPacket元头，以及由节点本地Dynamic Kernel处理的仅追加的动作提交戳，Dynamic Kernel被组织为规划器-执行器-引擎流水线，同时被限定在可分析验证的服务和策略范围内。在该限定设置中，我们通过链路准备策略研究节点异质性，该策略考虑了预分发的纠缠以及节点间不均衡的纠缠生成支持，包括通过QPacket转发进行的委托。仿真验证了可分析的链路可解析性模型，并揭示了信令负载、转发行为和QPacket元头增长情况。结果表明，QPacket开销不仅受编码影响，还受策略选择和可用网络资源的影响。总体而言，本研究证明了Q2NS/ns-3底层平台如何支持量子原生协议套件概念的可复现、特定策略的评估。
英文摘要
The Quantum Internet operates on entanglement, a non-local, non-copyable, stateful network resource, which motivates protocol organization beyond classical layering. We present a first executable specialization of the Dynamic Kernel/QPacket logic from the beyond-layering protocol suite, targeting entanglement distribution over a linear quantum repeater chain. The implementation builds on Q2NS, an ns-3-based quantum-network simulation module available through the ns-3 App Store. It realizes QPacket meta-headers with service intent and append-only action-commit stamps processed by node-local Dynamic Kernels organized as a Planner--Executor--Engine pipeline, while being deliberately scoped to an analytically verifiable service and policy. Within this scoped setting, we study node heterogeneity through a link-preparation policy that accounts for pre-distributed entanglement and uneven entanglement-generation support across nodes, including delegation via QPacket forwarding. Simulations verify analytical link-resolvability models and expose signaling load, forwarding behavior, and QPacket meta-header growth. Results show that QPacket overhead is shaped by more than just encoding, including policy choices and available network resources. Overall, this study demonstrates how the Q2NS/ns-3 substrate can support reproducible, policy-specific evaluation of quantum-native protocol-suite concepts.
