Despite the fact that Optical Packet Switching (OPS) emerges as a promising solution for future Data Center (DC) networks, towards increasing capacity and radix, while retaining sub-μs latency performance, the requirement for ultra-fast burst-mode reception has been a serious restraining factor. We attempt to overcome this limitation and demonstrate, for the first time to our knowledge, an end-to-end optical packet switch link through the 1024-port 25.6 Tb/s Hipoλaos OPS, featuring burst-mode reception with <50 ns locking time. The switch performance for unicast traffic is evaluated via Bit-Error-Rate measurements and error-free performance at 10 ⁻⁹ is reported for all validated port-combinations, with a mean power penalty of 2.88 dB. Moreover, multicast flows from two different ports of the switch were successfully received validating the architecture's credentials for efficient multicast packet delivery. Taking one step further towards a realistic evaluation of an OPS-enabled DC, a simulation analysis was conducted, proving that low-latency performance, including the burst-mode reception time-overhead, can be successfully realized in a Hipoλaos-switched DC with up-to 100% throughput for a variety of traffic profiles.

用于数据中心的具有 25 Gb/s 突发模式接收的端到端 1024 端口光分组交换

尽管光分组交换 (OPS) 已成为未来数据中心 (DC) 网络的有前途的解决方案，但为了增加容量和基数，同时保持亚微秒的延迟性能，对超快速突发模式接收的要求一直是一个严重的制约因素。我们试图克服这一限制，并首次展示了通过 1024 端口 25.6 Tb/s Hipoλaos OPS 的端到端光分组交换机链路，其特点是具有 <50 ns 锁定时间的突发模式接收. 单播流量的交换机性能通过误码率测量和 10 ^-9的无差错性能进行评估 报告了所有经过验证的端口组合，平均功率损失为 2.88 dB。此外，来自交换机两个不同端口的多播流被成功接收，验证了架构的凭据，以实现高效的多播数据包交付。进一步对启用 OPS 的 DC 进行现实评估，进行了仿真分析，证明低延迟性能，包括突发模式接收时间开销，可以在 Hipoλaos 开关 DC 中成功实现- 对各种流量配置文件达到 100% 的吞吐量。
