F4Tele:适用于数据中心网络管理和分组遥测的FSO

F4Tele: FSO for Data Center Network Management and Packet Telemetry

Amer AlGhadhban

摘要:

大量占用带宽的应用程序和服务迫使数据中心(DC)管理员优化可用资源的利用率。准确地说,管理流量的网络份额已经显著增长,因为DC网络变得越来越复杂,需要大量数据来进行有效的调试和故障排除。因此,我们使用自由空间光通信(FSO)与波分复用(WDM)技术,以建立一个灵活而高性能的逻辑网络,负责管理流量。FSO-WDM可以在视距(LoS)链路上提供可重构的多太比特拓扑。由于空间和处理能力的原因,我们不能提供从每个数据机架到网络管理机架的直接连接。可替代地,数据机架被分组在一起,因为每个组在与其平均到达率匹配的持续时间内被服务。由于数据机架显示出不同的到达率,热点机架被分配有更长的服务时间。评估结果表明,F4 Tele的高吞吐量接近昂贵的解决方案(基准)。

英文摘要:

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 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 management traffic. The FSO-WDM can provide reconfigurable multi-terabit topology over line-of-sight (LoS) links. Due to space and processing capacity reasons, we can not offer direct connections from every data rack to the network management racks. Alternatively, the data racks are grouped together as each group is serviced for a duration of time matches its average arrival-rate. Since the data racks showed different arrival-rates, the hotspot racks are allocated with longer service time. The evaluation results show that F4Tele carried out high throughput close to the expensive solution (benchmark).
