论文摘要
多链接操作（MLO）是下一个IEEE 802.11的关键功能，它是极高的吞吐量修正案。通过采用，预计它将通过提高吞吐量和延迟来增强用户的体验。但是，潜在的MLO收益与流量如何在多个无线电接口之间分布相关。在本文中，我们介绍了MLO上的流量管理器，并评估不同的高级流量到链接分配策略，以在启用的接口集上分发传入的流量。按照流级方法，我们将非动态和动态交通平衡策略类型进行比较。结果表明，使用动态政策以及MLO，可以显着减少交通流量所遭受的拥塞，在所有评估的方案中增强交通交付，尤其是提高视频流提供的服务质量。此外，我们表明，未来Wi-Fi网络中MLO的采用也改善了与非MLO网络的共存，这导致MLO和非MLO网络的性能提高。
The multi-link operation (MLO) is a key feature of the next IEEE 802.11be Extremely High Throughput amendment. Through its adoption, it is expected to enhance users' experience by improving throughput rates and latency. However, potential MLO gains are tied to how traffic is distributed across the multiple radio interfaces. In this paper, we introduce a traffic manager atop MLO, and evaluate different high-level traffic-to-link allocation policies to distribute incoming traffic over the set of enabled interfaces. Following a flow-level approach, we compare both non-dynamic and dynamic traffic balancing policy types. The results show that the use of a dynamic policy, along with MLO, allows to significantly reduce the congestion suffered by traffic flows, enhancing the traffic delivery in all the evaluated scenarios, and in particular improving the quality of service received by video flows. Moreover, we show that the adoption of MLO in future Wi-Fi networks improves also the coexistence with non-MLO networks, which results in performance gains for both MLO and non-MLO networks.
