【摘要】：在信息技術(shù)不斷發(fā)展的今天，人們對(duì)于獲取信息的需求越來(lái)越大。從內(nèi)容門戶網(wǎng)站到社交網(wǎng)站，從視頻娛樂(lè)到網(wǎng)絡(luò)游戲，無(wú)一不在挑戰(zhàn)著日趨超負(fù)荷的網(wǎng)絡(luò)設(shè)備。為了滿足人們對(duì)信息獲取的需要，改善用戶上網(wǎng)體驗(yàn)及適應(yīng)上層新技術(shù)的發(fā)展，生產(chǎn)更快更穩(wěn)定的網(wǎng)絡(luò)設(shè)備已經(jīng)是刻不容緩的事情。本文重點(diǎn)研究多核路由器的驅(qū)動(dòng)實(shí)現(xiàn)，通過(guò)對(duì)多核處理器的開發(fā)應(yīng)用，提高路由器的轉(zhuǎn)發(fā)性能。 本論文主要研究多核處理器的結(jié)構(gòu)與使用方法，并結(jié)合多核路由器的驅(qū)動(dòng)設(shè)計(jì)進(jìn)行分析。首先，論文明確了研究背景及國(guó)內(nèi)外相關(guān)的研究情況，然后概述了多核路由器需要用到的相關(guān)理論和技術(shù)，如XLP處理器、Comware V7系統(tǒng)等。接下來(lái)對(duì)路由器的硬件系統(tǒng)進(jìn)行了分析和描述，對(duì)路由器的軟件驅(qū)動(dòng)系統(tǒng)進(jìn)行了詳細(xì)描述及需求分析。在設(shè)計(jì)階段，本文將驅(qū)動(dòng)系統(tǒng)分為了BSP模塊、板間通信模塊、以太網(wǎng)接口模塊以及VCPU模塊，并對(duì)各模塊進(jìn)行分析設(shè)計(jì)。最后，對(duì)各模塊進(jìn)行具體實(shí)現(xiàn)，并通過(guò)多個(gè)測(cè)試用例，檢驗(yàn)工作效果。 通過(guò)本文的研究，，可以總結(jié)出一些常用多核應(yīng)用的方法及其改進(jìn)措施。這些方法使得系統(tǒng)在高效提升性能的同時(shí)，確保系統(tǒng)的穩(wěn)定性及可控性。這些研究雖然以路由器作為研究載體，但是其對(duì)多核系統(tǒng)都有實(shí)際意義。無(wú)論是大型服務(wù)器還是小型嵌入式家電，都會(huì)面臨性能的瓶頸，而多核技術(shù)正是解決性能問(wèn)題的一個(gè)重要手段，因此，多核技術(shù)的應(yīng)用價(jià)值是非常廣泛的。
[Abstract]:With the development of information technology, people need more and more information. Everything from content portals to social networking sites, from video entertainment to online games, is challenging increasingly overloaded network devices. In order to meet the needs of people to obtain information, improve the user experience and adapt to the development of new technology, it is urgent to produce faster and more stable network equipment. This paper focuses on the implementation of multi-core routers, through the development and application of multi-core processors to improve the forwarding performance of routers. This paper mainly studies the architecture and usage of multi-core processors, and analyzes the driver design of multi-core routers. Firstly, the research background and related research situation at home and abroad are clarified, and then the related theories and technologies used in multi-core routers are summarized, such as XLP processor, Comware V7 system and so on. Then the hardware system of the router is analyzed and described, the software driving system of the router is described in detail and the requirements are analyzed. In the design phase, the driver system is divided into BSP module, inter-board communication module, Ethernet interface module and VCPU module, and each module is analyzed and designed. Finally, the implementation of each module, and through a number of test cases to verify the effectiveness of the work. Through the research in this paper, we can summarize some common methods and improvement measures of multi-core applications. These methods ensure the stability and controllability of the system while improving the performance efficiently. Although routers are used as research carriers, these researches have practical significance for multi-core systems. Both large servers and small embedded appliances will face the bottleneck of performance, and multi-core technology is an important means to solve the performance problem, so the application value of multi-nuclear technology is very extensive.
