The proliferation of bandwidth-hungry applications and services forces datacenter (DC) administrators to optimize the utilization of available resources. Precisely, the network share of management traffic (NMT) has grown significantly because DC networks are becoming more sophisticated and require a massive amount of data for efficient debugging and troubleshooting. Accordingly, we use free space optics communication (FSO) with wavelength division multiplexing (WDM) technology to build a flexible yet high-performance logical network responsible for NMT. The FSO-WDM can provide reconfigurable multi-terabit topology over indirect line-of-sight (LoS) links. Due to space and processing capacity reasons, we cannot offer direct connections from every NMT source to the network management cluster. Alternatively, the NMT sources are grouped together as each group is serviced for a duration of time matches its average arrival-rate. Since the NMT sources showed different arrival-rates, the hotspot racks are allocated with longer service time. The evaluation results show that F4Tele carried out a throughput 72% of the expensive solution (benchmark).

占用大量带宽的应用程序和服务的激增迫使数据中心（DC）管理员优化了可用资源的利用率。准确地说，管理流量（NMT）的网络份额已显着增长，因为DC网络变得越来越复杂，并且需要大量数据才能进行有效的调试和故障排除。因此，我们使用具有波分复用（WDM）技术的自由空间光学通信（FSO）来构建负责NMT的灵活而高性能的逻辑网络。FSO-WDM可以通过间接视线（LoS）链路提供可重新配置的多兆位拓扑。由于空间和处理能力的原因，我们无法提供从每个NMT源到网络管理群集的直接连接。或者，NMT源被分组在一起，因为每个组的服务持续时间与其平均到达率匹配。由于NMT来源显示的到达率不同，因此为热点机架分配了更长的服务时间。评估结果表明，F4Tele的吞吐量是昂贵解决方案的72％（基准）。
