Description

光互联***、节点、光网络控制器和传输数据的方法Optical interconnect system, node, optical network controller and method for transmitting data

技术领域Technical field

本发明涉及通信领域，并且更具体地，涉及光互联***、节点、光网络控制器和传输数据的方法。The present invention relates to the field of communications and, more particularly, to optical interconnect systems, nodes, optical network controllers, and methods of transmitting data.

背景技术Background technique

应用数量和数据量的增加对现有计算机提出了更高的要求，而计算能力的提升离不开大容量、高带宽的内存支持。但由于电链路的阻抗匹配特性，内存带宽的增加必然引起容量的牺牲。光互连相比电互连在长距离带宽、带宽密度、功耗等方面都有很大优势，且可以有效的避免或降低阻抗失配问题。The increase in the number of applications and the amount of data puts higher demands on existing computers, and the increase in computing power is inseparable from the support of large-capacity, high-bandwidth memory. However, due to the impedance matching characteristics of the electrical link, an increase in memory bandwidth necessarily causes a sacrifice in capacity. Optical interconnects have great advantages over long-distance bandwidth, bandwidth density, power consumption, etc., and can effectively avoid or reduce the impedance mismatch problem.

同时，由于电互连传输距离的限制，目前的计算机(如高端服务器)设计通常为1个或者几个处理器为中心，周围紧密围绕内存，再***是输入/输出(Input/Output，I/O)框等，但是这些组件必须在一个或者几个机柜中。这种紧耦合的结构有以下弊端：由于印制电路板(Printed Circuit Board，PCB)板上还要布局内存，因此单板的处理器密度有限，影响计算能力；多种不同的组件给散热、供电设计带来了极大困难；需要扩展计算或存储能力时，必须以子节点(包括处理器、内存、硬盘和网卡等的计算机/服务器子节点)为单位增减，造成资源浪费等等。At the same time, due to the limitation of the transmission distance of the electrical interconnection, the current computer (such as high-end server) is usually designed with one or several processors as the center, and the surrounding is closely surrounding the memory, and then the peripheral is the input/output (Input/Output, I/ O) box, etc., but these components must be in one or several cabinets. This tightly coupled structure has the following drawbacks: due to the layout of memory on the Printed Circuit Board (PCB) board, the processor density of the board is limited, affecting computing power; a variety of different components for heat dissipation, Power supply design brings great difficulties; when it is necessary to expand computing or storage capacity, it must be increased or decreased by sub-nodes (including computer/server sub-nodes such as processors, memory, hard disks, and network cards), resulting in waste of resources and so on.

目前的计算、存储解耦的技术中，计算、存储单元通过集成在机柜(rack)内的电交换单元互连构成计算池、存储池，这些计算池和存储池通过更高级的电交换网络实现资源共享。资源池内部采用以太网(Ethernet)互连，外部采用PCIe互连。然而，在这种情况下，资源池之间的互连带宽、延时以及功耗依然存在瓶颈，影响数据传输效率。In the current computing and storage decoupling technology, the computing and storage units are interconnected by electrical switching units integrated in a rack to form a computing pool and a storage pool. The computing pools and storage pools are implemented through a more advanced electrical switching network. Resource Sharing. The resource pool is internally interconnected by Ethernet (Ethernet) and the outside is PCIe interconnected. However, in this case, there is still a bottleneck in the interconnection bandwidth, delay, and power consumption between resource pools, which affects data transmission efficiency.
