[Abstract]:Over the past few years, Internet traffic has grown exponentially because of the rise of streaming media, social networking, cloud computing, and so on, putting higher demands on data centers. These data centers are based on tens of thousands of servers interconnected through high-performance switches. Data center-oriented applications, such as cloud computing and search engine applications, are more data-intensive, requiring efficient interconnection between servers. Such interconnection makes the network more demanding for high bandwidth and low delay communication. What is more, in order to reduce the operation cost, these data centers must meet the requirements of low energy consumption. This paper focuses on the demand of high bandwidth and low energy consumption of optical network in data center, and adopts the solution of optical interconnection, focusing on the extensibility of network structure and the flexibility of switching. The design and research of data center internal optical interconnection structure are carried out in the aspects of the diversity of service granularity. The main work and innovation include the following aspects: (1) combining wavelength division multiplexing (WDM) technology with data center optical interconnection network, According to the characteristics of the optical network inside the data center and the service requirements, the current Ethernet network structure of the data center and the WDM optical network are fused, and the inter-cluster (inter-cluster) micro-mechanical optical switch and the intra-cluster (intra-cluster) micro-mechanical optical switch are cascaded. To cope with the data center network scale continues to expand the expansion of the demand. The structure adopts centralized unified control mode, and the configuration command is issued by the central controller and the path is calculated and optimized. (2) in the optical network supporting WDM data center, A MUX / DEMUXWSS structure based on multiplexing / demultiplexing device and wavelength selective switch is proposed. The switching module can converge and dredge traffic on the optical layer. Exchange services from different nodes with the same destination address to the same destination node at the same time. Multipoint to single point, multi-point to multi-point simultaneous communication. The module supports centralized control mode. (3) in the data center optical network with variable bandwidth transceiver, a MUX / DEMUXSSS structure based on multiplexing / demultiplexing device and spectrum selection switch is proposed. The structure makes full use of the finer granularity and higher spectrum efficiency of the flexible spectrum network, and outputs the superchannel services composed of multiple subcarriers generated by a single source node. Enables services going to different destination ports to be switched to the host node at the same time. To achieve point-to-multi-point, multi-point to multi-point instant communication. (4) A transmission and reception mode combining variable bandwidth transmitter and fixed grid transmitter in data center internal network is proposed. The single carrier frequency division multiplexing (SCFDM) technique is used as the support technology of the variable bandwidth transmit receiver. The traffic monitoring method is used in the control to distinguish and distinguish the different granularity services. In order to realize the maximum utilization of resources and reduce the blocking rate and delay of the system, the switching configuration of different transceivers is used. (5) A hybrid optical circuit and an optical interconnection structure within the optical burst switching data center are proposed. The server is connected directly with the hybrid optical circuit and the optical burst switch through the switch interface card embedded in the server, which saves the top switch of the cabinet, and completes the burst service in the data center by means of the burst convergent switch. By differentiating the sensitivity of service delay, the services with different transmission requirements are packed and converged together, and the switching route is realized by optical circuit switching switch and optical burst switching switch respectively.
