摘要:二十一世紀是信息化、網(wǎng)絡化時代，校園網(wǎng)已成為各學校必備的重要信息基礎設施，其規(guī)模和應用水平已成為衡量學校教學與科研綜合實力的一個重要標志，最近本人參與的為宜興市丁蜀外國語中學規(guī)劃建設的校園網(wǎng)，就是一個技術水平較高的校園網(wǎng)絡。 該校園網(wǎng)連接了教學樓、綜合樓、圖書館和校內(nèi)許多部門，并與接入了互聯(lián)網(wǎng)。為了實現(xiàn)一個可管理的、可靠的、高性能網(wǎng)絡，在網(wǎng)絡規(guī)劃設計時采用了下列技術措施： 層次化的結(jié)構設計方法，將網(wǎng)絡分為核心層和接入層。兩個層次的網(wǎng)絡設備協(xié)同工作，從而有效保證了網(wǎng)絡的高可靠性、高安全性。 在核心交換機之間部署Glbp，實現(xiàn)網(wǎng)關冗余，提高網(wǎng)絡的穩(wěn)定性。 在核心交換機與邊界路由器之間部署動態(tài)路由選擇協(xié)議OSPF，實現(xiàn)路由的動態(tài)通告和學習。 在網(wǎng)絡邊緣部署NAT，提供地址轉(zhuǎn)換，以有效利用有限的公網(wǎng)IP地址。 在接入層使用VLAN技術給用戶提供靈活的網(wǎng)絡接入服務，各VLAN相互隔離，減少網(wǎng)絡流量，提供安全性。同時為每一個VLAN配置一個生成樹，避免環(huán)路，提高穩(wěn)定性。 核心交換機之間通過使用鏈路捆綁技術，將多條物理鏈路捆綁在一起，實現(xiàn)高帶寬，高可用性。 為避免病毒和蠕蟲的泛濫，采用NetFlow技術，同時使用Qos來優(yōu)化網(wǎng)絡。 本文從校園網(wǎng)需要分析入手，論述了網(wǎng)絡設計原則、網(wǎng)絡方案設計，重點敘述了網(wǎng)絡設備選型及網(wǎng)絡配置方法。 關鍵詞 校園網(wǎng)；網(wǎng)絡規(guī)劃；網(wǎng)絡設計；NetFlow
Abstract:The twenty-first century is the age of the informatization and networking, campus network has become the necessary important information infrastructure of school, its size and application level has become the measure of school teaching and scientific research an important symbol of comprehensive strength, recently I participate in for the city of sichuan foreign language middle school of planning and construction of campus network, is a technology with higher levels of campus network Hierarchical structure design method, the network is divided into core layer and access layer. Two levels of network devices to work together, thus effectively guarantees the network of high reliability, high security. Between the core switch deployment Glbp, realizes the gateway redundancy, improve the stability of the network. Along the boundary of the core switches and routers between the deployment of dynamic routing protocol OSPF, routing dynamic notice and study. On the edge of the network deployment of NAT, provide address translation, in order to effective use of limited public IP address. In the access layer using VLAN technology to provide users with flexible network access services, each VLAN mutual isolation, reduce the network traffic, to provide security. At the same time for each VLAN configuration a spanning tree, avoid the loop, improve stability. Binding technology, through the use of the link between core switches to bundle multiple physical links together, achieve high bandwidth, high availability. To avoid the spread of viruses and worms, USES the NetFlow technology, at the same time use Qos to optimize network. From campus network needs analysis, this paper discusses the principle of network design, network design, focus on the network equipment selection and network configuration are described.
