网络可观测性、互联网路由、网络资源调度

       在安全可控的IPv6下一代互联网体系结构领域已开展十余年基础理论研究和核心技术攻关，在网络方向顶级学术会议（SIGCOMM、CCS、CoNEXT、NDSS、INFOCOM、ICNP）、期刊（TON、TPDS、TIFS）发表多篇论文，研究成果服务于军队、银行、政府、运营商等国计民生部门。近年来，在网络可观测性、互联网路由、网络资源调度等方面取得的重点研究成果包括：

1.网络可观测性：面向互联网、云计算、园区网络及新型终端等多元化场景，突破传统监测技术局限，构建基于多源数据融合的分析框架。通过研究加密流量分析技术、系统日志智能处理、全链路请求追踪等技术，结合机器学习与形式化验证方法，研发了低开销高精度数据采集探针、时序关联图谱分析引擎、异常检测与根因推理智能诊断平台。该系统支持细粒度网络状态感知与自动化故障和安全事件处置，已应用于国家关键信息基础设施安全防护。

2.互联网路由：针对互联网域内/域间路由及数据中心网络异构环境，提出分布式与集中式协同的路由架构。基于分层式路由优化模型，创新研发多路径动态选择算法、故障预测驱动的快速重路由机制及可靠性增强型流量工程方案，有效解决负载均衡、链路故障恢复与网络可靠性保障等核心问题，在维持现网设备兼容性的前提下，显著提升网络鲁棒性与服务可用性。

3.网络资源调度：面向云广域网与数据中心网络场景，建立服务等级协议（SLA）驱动的多维资源协同调度框架。通过融合智能流量调度引擎、自适应拥塞控制算法、虚拟化资源动态编排系统及可编程数据平面加速技术，实现计算、存储与网络资源的联合优化，在复杂网络环境下保障了用户端到端服务质量与资源利用效率。
