摘要:

针对资源池化软件定义无线电（SDR）设备对SRIO互联网络高带宽、低延迟、高可靠、可维护的核心需求，解决传统SRIO枚举方案路由固定、波形重构地址丢失、故障定位困难及冗余链路利用率低等痛点，本文设计并实现一种基于动态路由的SRIO网络管理系统。采用组件化建模思想构建物理层、接口层、应用层分层架构，抽象设备、服务、管理三类核心组件，基于面向对象方法完成7类核心C++类对象建模；设计基于最短路径的深度优先探测算法，实现多路径自动探测与冗余链路择优调度；通过IIC总线实现交换芯片寄存器读写接口，设计以链路管理为核心机制的动态路由实现方法，实现链路生命周期管理与故障闭环处理。实验验证表明，该系统具备充分利用冗余链路的能力，波形重构链路恢复时间平均为66.6 ms（性能提升86.6%），故障定位时间≤300 ms，自愈成功率达100%，显著优于传统方案。该系统可满足资源池化SDR设备应用需求，具备较强工程实用性与推广价值，为复杂SRIO网络高效管理提供可行技术方案。

Abstract:

To satisfy the demands of pooled SDR devices for SRIO networks with high bandwidth, low latency, high reliability and maintainability, this paper designs and implements an SRIO network management system based on dynamic routing to overcome defects of traditional enumeration routing such as fixed paths, destination ID loss in waveform reconstruction, hard fault diagnosis and low redundant link utilization. A three-layer componentized architecture is established, seven C++ core classes are modeled by object-oriented methods, and a shortest-path DFS algorithm is adopted for multi-path search and redundant link scheduling. Register access of switching chips is realized via IIC, and a link-management-centric dynamic routing mechanism completes link lifecycle control and full fault closed-loop processing. Tests show the system recovers links within 66.6 ms on average during waveform reconstruction (86.6% performance boost), localizes faults within 300 ms and achieves 100% self-recovery rate, surpassing conventional solutions. It meets the engineering requirements of pooled SDR equipment and offers an effective scheme for complex SRIO network management.
