复旦大学校园网主干网络及配置.doc

复旦大学校园网是一个综合高效的教学和科研的校园计算环境。它不仅是一个大型的网络通讯平台，而且是一个基于宽带网络，集成多种应用，并具有强大的资源管理和安全防范机制的综合服务体系。其主干网络采用光纤通讯介质，以622M ATM技术为基础，融合155M ATM和光纤快速以太网等多种通讯技术基本覆盖了整个校园。在高层网络协议方面以Intranet模型为基本架构，多数上层应用完全基于TCP/IP协议族实现。

一． 网络结构

1．物理层:

校园网物理拓扑采用分级网络构，即将校园骨干网分为核心网和分支网两部分。核心网络层是整个系统的中心，它提供一个高速ATM的网络通信平台以及网络核心管理服务，由三个核心节点及一组12芯多模光纤、一组4芯单模光纤组成环型网络。分支网络由核心节点向外辐射到各院系大楼的4芯光缆和上行的节点设备组成。院系大楼的局域网则通过上行节点设备连入校园骨干网。现有分支网节点45个。分级网络的拓扑结构如下图所示。

校园网分级网络拓扑结构示意图

2．与ATM相关层次
校园网络以622M和155M ATM为基础通讯平台，采用LANE和MPOA技术实现与传统以太网和TCP/IP协议的融合，支持UNI 3.0/3.1UNI 4.0 IISP PNNI1.0等接口协议，支持SVC 、PVC和线路冗余，支持LANE 1.0和MPOA 1.0，可实现QoS（服务质量）控制。ATM网络拓扑结构示意图如下。

3．Ethernet 和TCP/IP层
提供符合IEEE 802.X标准的10M、100M双绞线和光纤以太网接口，并且具备千兆以太网的升级能力，系统支持基于MAC、Port、应用等多种VLAN的划分功能，虚网间通讯通过三层交换实现，虚网间有基于地址和应用的安全控制策略。作为支持路径选择和广播等功能的重要设备如MPOA(LANE) Server支持冗余，发生故障时可实现透明替换。

二． 网络设备

1． 核心交换机：
校园网的核心交换机为Cisco Catalyst 5500，模块配置如下：
¨ WS-X5530-E1 Catalyst 5000系列的主控模块（2/3宽）
¨ WS-U5533-FEFX-MMF 双口千兆以太网模块（1/3宽）
¨ WS-X5304-15 路由交换模块（占两个插槽）
¨ WS-X5161 双多模SC口，622M的 LANE模块（全宽）
¨ WS-X5225R 24个RJ45口10/100M自适应的以太网模块（全宽）
¨ WAI-OC12-1SS 622M的ATM模块，单口，单模SC接口（半宽）
¨ WAI-OC12-1MM 622M的ATM模块，单口，多模SC接口（半宽）
¨ WAI-OC3-4MM 155M的ATM模块，4口，多模SC接口（半宽）
¨ WAI-ATM25-12P 25M的ATM模块，12口（半宽）
¨ WATM-CAM-2P LightStream 1100，ATM控制模块（全宽）
其中，各交换机配置略有不同，基本都具有以上模块，但只有综合楼的Catalyst 5500配置有路由交换模块。各交换机内部，都有一对多模光纤将一块WAI-OC12-1MM与WS-X5161相连，解决ATM网络与LANE SERVER之间的连接问题；有一根双绞线将WS-X5225R的1号端口与WATM-CAM-2P相连，便于通过Telnet方式访问LightStream 1100。
各核心交换机的软件主要配置如下：
