Controlled Deep Reinforcement Learning for Optimized Slice Placement
摘要:
我们提出了一种混合ML启发式方法,我们命名为“启发式辅助深度强化学习(HA-DRL)”来解决网络切片放置优化问题。所提出的方法利用最近的工作深度强化学习(DRL)切片放置和虚拟网络嵌入(VNE),并使用启发式函数优化探索的行动空间,优先考虑可靠的行动表示一个有效的启发式算法。评估结果表明,所提出的HA-DRL算法可以加速学习一个有效的切片放置策略,提高切片接受率相比,国家的最先进的方法,仅基于强化学习。
英文摘要:
We present a hybrid ML-heuristic approach that we name "Heuristically Assisted Deep Reinforcement Learning (HA-DRL)" to solve the problem of Network Slice Placement Optimization. The proposed approach leverages recent works on Deep Reinforcement Learning (DRL) for slice placement and Virtual Network Embedding (VNE) and uses a heuristic function to optimize the exploration of the action space by giving priority to reliable actions indicated by an efficient heuristic algorithm. The evaluation results show that the proposed HA-DRL algorithm can accelerate the learning of an efficient slice placement policy improving slice acceptance ratio when compared with state-of-the-art approaches that are based only on reinforcement learning.
