摘 要：“基于Cisco技術(shù)的某學(xué)校網(wǎng)絡(luò)規(guī)劃設(shè)計(jì)與實(shí)現(xiàn)”，在這個(gè)設(shè)計(jì)中用到了Cisco的交換與路由技術(shù)、Cisco的安全技術(shù)等等。
基于Cisco技術(shù)的某學(xué)校網(wǎng)絡(luò)規(guī)劃設(shè)計(jì)與實(shí)現(xiàn)是完成一個(gè)學(xué)校的網(wǎng)絡(luò)通信，用有限的資金最優(yōu)的完成網(wǎng)絡(luò)通信問(wèn)題。學(xué)校的幾個(gè)主要地方都可以在內(nèi)部進(jìn)行通信也可以和外部進(jìn)行通信。在這個(gè)設(shè)計(jì)中分成了三個(gè)層次，最上面是核心層，用的是千兆的帶寬；其次是分布層，用的是百兆的帶寬；最下面是接入層，在接入層中針對(duì)不同的用戶需求，用不同的帶寬，但以十兆為大多數(shù)。每個(gè)不同的層次有不同的功能，核心層在學(xué)校的中心機(jī)房，主要負(fù)責(zé)這個(gè)學(xué)校的網(wǎng)絡(luò)維護(hù)，內(nèi)部網(wǎng)絡(luò)與外部網(wǎng)絡(luò)的通信，提供高的可靠性，提供冗余鏈路等等；分布層是網(wǎng)絡(luò)核心層和接入層之間的分界點(diǎn)，這一層主要功能實(shí)現(xiàn)如策略、安全、VLAN、路由間的重分布，靜態(tài)和動(dòng)態(tài)路由選擇協(xié)議之間的劃分，介質(zhì)翻譯等等；接入層是為用戶提供對(duì)網(wǎng)絡(luò)中的本地網(wǎng)段的訪問(wèn)，對(duì)分布層的訪問(wèn)控制和策略進(jìn)行支持，建立獨(dú)立的沖突域等等。
在這個(gè)設(shè)計(jì)中最重要也是最關(guān)鍵的是Cisco公司的交換機(jī)和路由器進(jìn)行配置，在配置時(shí)是按照設(shè)計(jì)時(shí)的層次來(lái)的這樣可以減少出錯(cuò)并且能更加的體現(xiàn)每一層次的特點(diǎn)、功能。加在遠(yuǎn)程訪問(wèn)路由器后面的PIX防火墻是Cisco公司著名的軟硬件結(jié)合的專用安全設(shè)備，所有流經(jīng)PIX的數(shù)據(jù)都必須接受嚴(yán)格而全面的檢驗(yàn)，檢驗(yàn)內(nèi)容包括數(shù)據(jù)的源和目標(biāo)地址、TCP隨機(jī)序列號(hào)、TCP端口號(hào)和附加標(biāo)志等，只有滿足特定條件的數(shù)據(jù)才能穿過(guò)這道防火墻。
在網(wǎng)絡(luò)規(guī)劃和設(shè)計(jì)過(guò)程中，從完成拓?fù)涞阶詈蟮臏y(cè)試都非常順利。

2 Abstract
Abstract: "Based on Cisco technology in a school network design and implementation " In this design used in the Cisco exchange and routing technology、Cisco's security technology, and so on.
Based on Cisco technology in a school network planning 、design and implementation of a complete communications network of schools, with limited funds to complete the optimal network communications. Several schools are the main places in the internal communication can and external communications. In the design carved into three levels, the top of the core layer, with the gigabit bandwidth; Secondly, the distribution layer, the 100M is the bandwidth; Access is the lowermost layer, access layer for different needs of users with different bandwidth. But for the majority of advances.，each different levels have different functions, the core layer in the center of the school room, primarily responsible for the maintenance of the school network, the internal network and external communications network to provide high reliability, provide redundant links, and so on. Distribution of the core layer is the network layer and the access layer boundaries, This layer of the main functions of achieving such as strategy, security, VLAN, the re-routing distribution, Static and dynamic routing agreement between the division and medium interpreters; Access layer is to provide users of the network of local network visit to the distribution layer of access control and support strategy, the establishment of an independent conflict-domain, and so on.
In this design the most important and most crucial is Cisco's switches and routers configured It was in accordance with the design of the level of such errors can be reduced and can be more a reflection of the characteristics of each level. Added to the Remote Access Router behind Cisco PIX firewall is a well-known software company with special security set up equipment, all the data flowing through PIX had to be rigorous and comprehensive testing, test data including the source and destination addresses, TCP random sequence, TCP port, and additional signage. only by meeting specific conditions of this data across firewalls. Network planning and design process, from the completion of the final topology of the tests are very smoothly.
