论文摘要
多链接操作（MLO）是一项新功能，旨在属于IEEE 802.11BE的一部分非常高的吞吐量（EHT）修正案。该功能代表向多链接通信的范式转移，因为将允许节点同时通过多个无线电接口传输数据。为了使其成为可能，802.11BE任务组就节点的体系结构，传输操作和管理功能提出了不同的修改。本文回顾了此类变化，并解决了应如何通过多个链接分发流量的问题，因为它仍未解决。为此，我们评估了主动链接上不同的负载平衡策略。结果表明，在高负载，密集和复杂的情况下，必须使用MLO来显着提高下一代WLAN性能。
The multi-link operation (MLO) is a new feature proposed to be part of the IEEE 802.11be Extremely High Throughput (EHT) amendment. Such feature represents a paradigm shift towards multi-link communications, as nodes will be allowed to transmit and receive data over multiple radio interfaces concurrently. To make it possible, the 802.11be Task Group has proposed different modifications in regards to nodes' architecture, transmission operation, and management functionalities. This article reviews such changes and tackles the question of how traffic should be distributed over multiple links, as it is still unresolved. To that end, we evaluate different load balancing strategies over the active links. Results show that in high load, dense and complex scenarios, implementing congestion-aware load balancing policies to significantly enhance next-generation WLAN performance using MLO is a must.
