This paper reports on the first user/application-driven multi-technology optical sub-wavelength network for intra/inter Data-Centre (DC) communications. Two DCs each with distinct sub-wavelength switching technologies, frame based synchronous TSON and packet based asynchronous OPST are interconnected by a WSON inter-DC communication. The intra/inter DC testbed demonstrates ultra-low latency (packet-delay <270 µs and packet-delay-variation (PDV)<10 µs) flexible data-rate traffic transfer by point-to-point, point-to-multipoint, and multipoint-to-(multi)point connectivity, highly suitable for cloud based applications and high performance computing (HPC). The extended GMPLS-PCE-SLAE based control-plane enables innovative application-driven end-to-end sub-wavelength path setup and resource reservation across the multi technology data-plane, which has been assessed for as many as 25 concurrent requests.
本文报道了首个用户/应用驱动的多技术光亚波长网络，用于数据中心内部/数据中心间通信。两个分别采用不同亚波长交换技术（基于帧的同步TSON和基于分组的异步OPST）的数据中心，通过WSON数据中心间通信相互连接。数据中心内部/数据中心间测试平台展示了超低延迟（分组延迟<270微秒，分组延迟变化（PDV）<10微秒），通过点对点、点对多点和多点对（多）点连接实现灵活的数据速率流量传输，非常适合基于云的应用和高性能计算（HPC）。基于扩展GMPLS-PCE-SLAE的控制平面实现了创新的应用驱动的端到端亚波长路径设置和跨多技术数据平面的资源预留，该控制平面已针对多达25个并发请求进行了评估。
