用强化学习让网络自动选最优路径,实时响应拥塞变化。
Reinforcement Learning-based Adaptive Path Selection for Programmable Networks
- 结合随机学习自动机与实时网络探针数据,实现本地自适应路由。
- 在Mininet测试中,路径选择在光速下收敛并动态适应网络变化。
- 适合研究可编程网络自优化的工程师和学者。
本文提出一种分布式、基于网络内强化学习(IN-RL)的自适应路径选择框架,用于可编程网络。通过将随机学习自动机(SLA)与基于带内网络探测(INT)实时采集的遥测数据结合,系统实现基于数据的本地转发决策,能动态响应拥塞状况。在基于Mininet的测试平台上,使用P4可编程BMv2交换机进行评估,验证了所提SLA机制可在线速率下快速收敛至有效路径选择,并持续适应网络条件变化。
原文摘要 · Abstract (English)
This work presents a proof-of-concept implementation of a distributed, in-network reinforcement learning (IN-RL) framework for adaptive path selection in programmable networks. By combining Stochastic Learning Automata (SLA) with real-time telemetry data collected via In-Band Network Telemetry (INT), the proposed system enables local, data-driven forwarding decisions that adapt dynamically to congestion conditions. The system is evaluated on a Mininet-based testbed using P4-programmable BMv2 switches, demonstrating how our SLA-based mechanism converges to effective path selections and adapts to shifting network conditions at line rate.
