The paper presents a novel network architecture on demand approach using on-chip and-off chip implementations, enabling programmable, highly efficient and transparent networking, well suited for intra-datacenter communications. The implemented FPGA-based adaptable line-card with on-chip design along with an architecture on demand (AoD) based off-chip flexible switching node, deliver single chip dual L2-Packet/L1-time shared optical network (TSON) server Network Interface Cards (NIC) interconnected through transparent AoD based switch. It enables hitless adaptation between Ethernet over wavelength switched network (EoWSON), and TSON based sub-wavelength switching, providing flexible bitrates, while meeting strict bandwidth, QoS requirements. The on and off-chip performance results show high throughput (9.86Ethernet, 8.68Gbps TSON), high QoS, as well as hitless switch-over.
本文提出了一种新颖的按需网络架构方法，采用片上和片外实现方式，实现了可编程、高效且透明的网络，非常适合数据中心内部通信。所实现的基于现场可编程门阵列（FPGA）的适应性线卡与片上设计以及基于按需架构（AoD）的片外灵活交换节点，提供了单芯片双L2分组/L1时间共享光网络（TSON）服务器网络接口卡（NIC），通过基于透明AoD的交换机互连。它能够在波长交换以太网（EoWSON）和基于TSON的子波长交换之间进行无冲击适配，提供灵活的比特率，同时满足严格的带宽、服务质量（QoS）要求。片上和片外性能结果显示出高吞吐量（9.86以太网，8.68Gbps TSON）、高QoS以及无冲击切换。
