AI总结:

针对 B5G O-RAN 中多个 xApps 部署重叠引发冲突的问题,提出 xApp 蒸馏方法,将多个 xApps 的知识蒸馏到单一模型,实验表明其网络中断次数显著低于对比方案。

摘要:

基于机器学习(ML)的决策算法的进步创造了各种研究和工业机会。其中一个领域是开放无线接入网(O-RAN)中基于 ML 的近实时网络管理应用(xApps)。通常,xApps 仅针对期望目标进行设计,并针对部署进行微调。然而,电信公司可以部署多个 xApps,并将其部署在重叠区域中。考虑到 xApps 的不同设计目标,部署可能会引起冲突。为了防止此类冲突,我们提出了 xApp 蒸馏方法,该方法从多个 xApps 中蒸馏知识,然后利用这些知识训练一个保留了先前 xApps 能力的单一模型。性能评估表明,在某些情况下,对比的冲突缓解方案导致的网络中断次数最多可达 xApp 蒸馏的六倍。

英文摘要:

The advancements of machine learning-based (ML) decision-making algorithms created various research and industrial opportunities. One of these areas is ML-based near-real-time network management applications (xApps) in Open-Radio Access Network (O-RAN). Normally, xApps are designed solely for the desired objectives, and fine-tuned for deployment. However, telecommunication companies can employ multiple xApps and deploy them in overlapping areas. Consider the different design objectives of xApps, the deployment might cause conflicts. To prevent such conflicts, we proposed the xApp distillation method that distills knowledge from multiple xApps, then uses this knowledge to train a single model that has retained the capabilities of Previous xApps. Performance evaluations show that compared conflict mitigation schemes can cause up to six times more network outages than xApp distillation in some cases.
