【摘要】：隨著高性能計(jì)算機(jī)的不斷發(fā)展，，互連網(wǎng)絡(luò)對(duì)于計(jì)算機(jī)整體性能的提升越來(lái)越重要。傳統(tǒng)的電互連網(wǎng)絡(luò)存在著帶寬小、延遲大、互聯(lián)密度小等不足，已經(jīng)無(wú)法滿足對(duì)互連網(wǎng)絡(luò)性能的需求，成為制約高性能計(jì)算機(jī)性能提高的瓶頸，需要一種新的互連方式來(lái)解決。光互連作為一種新的互連方式，具有許多優(yōu)勢(shì)，如高度的并行性，抗干擾能力強(qiáng)，高帶寬低功耗等。光互連的應(yīng)用已經(jīng)被人們所認(rèn)可，關(guān)于光互連相關(guān)技術(shù)的研究也在不斷發(fā)展進(jìn)步。 光互連網(wǎng)絡(luò)中控制光傳輸路徑的核心單元是光交換陣列，目前對(duì)于光交換陣列的設(shè)計(jì)分析都是基于相應(yīng)的網(wǎng)絡(luò)結(jié)構(gòu)，路由算法，而對(duì)于光交換陣列本身的研究還不充分，尤其在設(shè)計(jì)方法上，缺少通用的光交換陣列設(shè)計(jì)方法來(lái)適應(yīng)不同的網(wǎng)絡(luò)結(jié)構(gòu)。 本文針對(duì)上面提到的問(wèn)題，對(duì)光交換陣列的應(yīng)用環(huán)境，不同功能的光交換陣列等進(jìn)行了分析，主要完成以下幾個(gè)方面的工作： 1設(shè)計(jì)了一種和Crossbar結(jié)構(gòu)一樣能夠?qū)崿F(xiàn)完整互連特性的光交換陣列結(jié)構(gòu)CCOS（Completely-Connected Optical Switch），大幅降低了各項(xiàng)硬件開銷及插入損耗，并從理論和實(shí)驗(yàn)兩個(gè)方面進(jìn)行了論證； 2將CCOS光交換陣列擴(kuò)展成為N×N規(guī)模，并對(duì)其完整互連的性質(zhì)給出證明，還研究了不同規(guī)模下的光交換陣列所花費(fèi)硬件開銷的最小值，對(duì)光交換陣列的優(yōu)化設(shè)計(jì)提供了標(biāo)準(zhǔn)和理論依據(jù)，為進(jìn)一步擴(kuò)展實(shí)現(xiàn)較大規(guī)模的網(wǎng)絡(luò)結(jié)構(gòu)提供了基礎(chǔ)； 3對(duì)不同功能需求的光交換陣列特點(diǎn)進(jìn)行分析，特別區(qū)分了N×N完整互連與N端口全互連的光交換陣列，并從現(xiàn)有的結(jié)構(gòu)出發(fā)，分析不同陣列結(jié)構(gòu)的設(shè)計(jì)，提出基于不同網(wǎng)絡(luò)需求的較為通用的光交換陣列設(shè)計(jì)方法；對(duì)于光交換陣列性能的提高以及新型網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)的搭建有著積極意義。
[Abstract]:With the development of high performance computer, interconnection network is becoming more and more important to improve the overall performance of computer. The traditional electrical interconnection network has some disadvantages, such as small bandwidth, large delay, low interconnection density and so on. It can not meet the demand for the performance of interconnection network and has become the bottleneck restricting the improvement of the performance of high performance computer. It needs a new interconnection method to solve the problem. As a new interconnection mode, optical interconnection has many advantages, such as high parallelism, strong anti-jamming ability, high bandwidth and low power consumption. The application of optical interconnection has been recognized by people. The core unit of optical transmission path control in optical interconnection network is optical switching array. At present, the design and analysis of optical switching array are based on the corresponding network structure, routing algorithm, but the research on optical switching array itself is not enough. Especially in the design method, there is a lack of general optical switch array design method to adapt to different network structure. In this paper, the application environment of optical switching array and optical switching array with different functions are analyzed. The main work of this paper is as follows: 1 an optical switching array (CCOS) structure, which can realize the complete interconnection characteristics as Crossbar architecture, is designed. (Completely-Connected Optical Switch), greatly reduces the hardware overhead and insertion loss. And from the theoretical and experimental two aspects of the argument; (2) the CCOS optical switching array is extended to N 脳 N scale, and the properties of its complete interconnection are proved. The minimum hardware cost of the optical switching array with different scales is also studied. It provides the standard and theoretical basis for the optimization design of optical switching array, and provides the basis for further expanding and realizing the larger network structure. (3) the characteristics of optical switching arrays with different functional requirements are analyzed, especially the optical switching arrays with N 脳 N complete interconnection and N port complete interconnection are distinguished, and the design of different array structures is analyzed based on the existing structures. A general optical switching array design method based on different network requirements is proposed. It is of great significance to improve the performance of optical switching arrays and to build new network topology.
