河北师范大学新校区校园无线局域网方案设计

校园网已经成为校园生活的重要组成部分,是教职员工和学生获取资源和信息的主要途径。

目前,越来越多的学生拥有笔记本电脑,在教室、实验室、图书馆、大型会议室、体育馆、室外广场等场合如何突破有线网络节点的限制,解决多路同时上网的问题不可避免。

然而无线网络的技术已经成熟,足以支撑起种类繁多的应用,随时随地为用户提供稳定高速的接入服务。

可以选择的无线网络解决方案很多,实际部署中要充分考虑现实的条件和实际的需求确定最优的方案,以达到期望的效果。

本文首先分析了校园无线局域网的应用需求,制定了河北师范大学新校区校园无线局域网的整体设计方案。

之后进行了具体的网络分析、拓扑设计、原理实现和设备选型,完成了建设校园无线网络的详细方案。

方案的创新点在于对校园有线网进行了有效补充。

OSPF协议概述

OSPF协议概述

OSPF协议概述OSPF(Open Shortest Path First)是一种用于内部网关协议(IGP),常用于大型企业网络或互联网服务提供商的路由器之间的通信。

它是一个开放的标准协议,由RFC 2328定义。

OSPF协议的设计目标是提供一个可扩展、灵活且稳定的路由协议,以适应复杂网络环境。

它采用链路状态路由算法,通过建立拓扑数据库来计算最短路径,并更新路由表。

OSPF协议的核心概念包括以下几个方面:1. 邻居关系建立:OSPF协议使用Hello报文来发现相邻路由器,并建立邻居关系。

通过交换Hello报文,路由器可以确认邻居的可达性,并协商参数,如路由器ID、优先级等。

2. 拓扑数据库构建:邻居关系建立后,路由器会交换链路状态更新(LSU)报文,其中包含链路状态信息。

每个路由器会根据收到的LSU报文更新自己的拓扑数据库,记录网络中所有路由器和链路的状态。

3. 最短路径计算:根据拓扑数据库中的信息,每个路由器使用Dijkstra算法计算出到达目的地的最短路径。

计算结果存储在路由表中,用于转发数据包。

4. 路由表更新:当拓扑数据库发生变化时,路由器会更新自己的路由表。

OSPF协议使用可变长子网掩码(VLSM)来支持更灵活的路由表更新。

5. 路由器类型:OSPF定义了不同类型的路由器,包括主干路由器(Backbone Router)、区域边界路由器(Area Border Router)和内部路由器(Internal Router)。

每种类型的路由器在拓扑数据库和路由表的更新过程中有不同的角色和责任。

6. 路由器优先级:OSPF协议使用路由器优先级来确定主备路由器。

具有更高优先级的路由器将成为主路由器,处理路由计算和更新任务,而具有较低优先级的路由器将成为备份路由器。

7. 路由器区域划分:为了提高扩展性和性能,OSPF将网络划分为多个区域(Area)。

每个区域内部的路由器只需了解本区域的拓扑信息,而不需要了解整个网络的拓扑。

OSPF 版本 2/第二稿
本文档描述了开放最短路径优先/Open Shortest Path First(OSPF)TCP/IP 网际路由协议。 OSPF 是一种典型的内部网关协议/Interior Gateway Protocol(IGP)。这意味着其路由信息是描述 属于同一个自制系统/Autonomous System(AS)中的路由器。OSPF 协议是基于连接状态或被称 为 SPF 的技术,这与传统 TCP/IP 网际路由协议所使用的 Bellman-Ford 技术不同。

关于JNCIE考试:
JNCIE的考试都分笔试和实验两部分,笔试称为JNCIS (Juniper Networks Certified Internet Specialist), 即资格考试,顾名思义,必须通过了笔试部分的考试,才能参加实验部分的考试, 其实JNCIS是一个独立的认证考试, 考过了以后也可以发证书, 但是我们这里讨论的是JNCIE考试, 对于JNCIS就不做详细的单独介绍。JNCIS考试在中国各个城市基本都能考, 就是通过Prometric的考试中心来进行考试(VUE是不能考的), 也就是说, 只要能考CCNA认证或者MCSE认证的地方, 就都能考JNCIS,而实验室部分,在全球只有为数不多的6-7个考场左右。目前中国可以考JNCIE/JNCIP。

OSPF常用术语
(1) OSPF AS (Autonomous System):运行OSPF协议的路由域 (2) Area:一个OSPF区域内的所有路由器都拥有相同的链路状态数 据库。 (3) Router ID:用于标识OSPF路由器的ID,全网唯一性;可手动 配置,也可动态选举(有Loopback接口时,选择最高的Loopback IP地址;否则,选择最高的物理接口的IP地址)。 (4) 接口:路由器上,启动了OSPF的接口。 (5) 邻居:在同一链路上,参数一致的路由器才能形成邻居。 (6) 进程:OSPF路由协议进程,进程号只在本路由器内起作用, OSPF协议包中并不携带进程号。
课程议题
一、OSPF概述 概述
1、OSPF概述
(1) OSPF(Open Shortest Path First,开放最短路径优先)是 一种链路状态路由协议,无路由循环(全局拓扑),属于IGP。 RFC 2328,“开放”意味着非私有的,对公众开放的。 (2) OSPF的报文封装 OSPF协议包直接封装于IP,协议号89。 三个版本 v1、 v2(ipv4)v3 (ipv6) OSPF协议包目标IP为组播地址 所有OSPF路由器——224.0.0.5;OSPF DR BDR——224.0.0.6 (3) OSPF路由的度量值:用更合理的接口带宽来衡量路径开销。 到目标网络的路径(数据出口)开销和。路径开销=参考带宽 (10的八次方)/ 链路带宽(出接口带宽 bit) (4) OSPF路由协议的管理距离:110

LSA类型
Router-LSA 由每个路由器生成,描述了路由器的链路状 态和花费,传递到整个区域
Network-LSA,由DR生成,描述了本网段的链路状态, 传递到整个区域
Net-Summary-LSA,由ABR生成,描述了到区域内某一 网段的路由,传递到相关区域
分别有哪些LSA? 5:OSPF有哪些协议报文?
解答
1:不会。必须重置OSPF进程或者重启路由器。 2:SPF计算最短路径树,以自己为根的、其它
路由器为叶的单向树。
3:OSPF协议在生成LSA时,首先将自己 的Router ID加入到LSA中,但是如果该路 由信息传递超过两个区域后就会丧失最初 的生成者的信息。。
OSPF Packet
HELLO协议报文(一)
HELLO协议报文的作用: 1:发现邻居 2:宣告一些参数,这些参数必须相同才能建立邻居关系 3:维护邻居关系 4:在邻居之间建立双向的通信 5:在多路访问网络中选举DR和BDR
HELLO协议报文(二)
HELLO协议报文的内容:
OSPF HEADER
Asbr-Summary-LSA,由ABR生成,描述了到ASBR的 路由,传递到相关区域
AS-External-LSA,由ASBR生成,描述了到AS外部的 路由,传递到整个AS(STUB区域除外)
问题
1:ROUTER ID修改之后,会立即生效? 2:OSPF为什么是无自环的? 3:为什么OSPF 区域必须和骨干区域相连? 4:在STUB区域、骨干区域、NSSA区域
相对RIP,OSPF具有很多的优点:
1: 无路由自环 2 :可适应大规模网络 3 :路由变化收敛速度快 4 :支持区域划分 5 :支持等值路由 6 :支持验证 7 :支持路由分级管理 8 :支持以组播地址发送协议报文

德尔网络Z9000产品说明说明书

Highly-available, high-performance Active Fabric spineThe Dell Networking Z9000 is a high-performance, efficient switch-router product designed to meet the requirements for high density 10/40GbE aggregation in a data center core network. The Z9000 switch is designed to address the East/West traffic patterns of modern data centers, providing higher performance and bandwidth across the data center for server to server communications. The Z9000 fabric switch can support 32 ports of 40GbE QSFP+ or 128 ports of 10GbE SFP+ realized through breakout cables. Supporting a full suite of Ethernet switching and routing protocols in the hardened Dell Networking OS, the Z9000 fabric switch can enable an Active Fabric™ via Layer 2 or Layer 3 protocols.An Active Fabric design with Z9000 switches can be built outto create scalable, high-performance 10/40GbE data center networks. The resiliency of an Active Fabric is superior to legacy, centralized core architectures, since the failure of a single node within a CLOS network cannot bring down the entire switching fabric. A single switching element can be restarted or replaced in the event of a failure versus an entire chassis reboot required in a centralized design.The Z9000 is supported with Active Fabric Manager (AFM), which helps automate design and deployment of multi-tier fabrics. AFM helps customers manage multiple fabrics from a single console, enabling a unified view of the entire fabric, when combinedwith Dell OMNM and other management solutions. With AFM, over 25 templates can be customized for specific workloadand deployment scenarios, easily delivering active-active L2or L3 designs for 1/10/40G with Z9000 to rack (with top-of-rack switches including Dell S4810/S4820T, S6000) and blade infrastructures (including Dell MXL).Key applications• Containerized data centers and prover-hosted data centers• Enterprise DC core aggregating 10/40GbE, cloud computing, high-performance cores• High-performance SDN/OpenFlow 1.0 enabled with ability to inter-operate with industry standard OpenFlow controllers Key features• 2RU high-density 10/40GbE fabric/core switch with 32 x 40GbE ports expandable to 128 x 10GbE ports using QSFP+ to SFP+ breakout cables• 2.5Tbps (full-duplex) non-blocking, fabric delivers line-rate performance under full load• Virtual link trunking (VLT) and enhanced VLT for layer 2 multipathing• Modular Dell Networking OS software delivers inherent stability as well as advanced monitoring and serviceability functions • Supported with Active Fabric design and Active Fabric Manager to reduce design, configuration and management for active/active deployments• Total aggregated packet buffer memory of 54MB for line-rate processing• 128 link aggregation groups with up to eight members per group, using advanced hashing with random seed values• Reversible front-to-back or back-to-front airflow• Supports jumbo frames for high-end server connectivity• Redundant, hot-swappable power supplies and fans• Low power consumption• Supports OpenFlow 1.0 in hybrid mode• Supports new QSFP+ PSM4, SR and ESR transceiver/cablesDell Networking Z9000Data center core fabric switchHigh-density 32-port 40GbE core router/switch in 2RU form factor; line rate, non-blocking, low-latency and lower power, enabling a greener, faster data center; feature-rich Dell Networking OS.High-performance,efficient fabric switchfor modern data centertraffic.© 2013 Dell, Inc.

版权提示:Copyright (C) The Internet Society (1998). All Rights Reserved.摘要:本备忘录说明了OSPF协议版本2。

OSPF是一种连接状态/link-state路由协议,被设计用于单一的自制系统/Autonomous System中。

每个OSPF路由器都维持着同样的数据库以描述AS的拓扑结构,并以此数据库来创建最短路径树并计算路由表。

OSPF在发现拓扑改变后,仅利用很少的路由流量就可以快速的重新计算出路径。

OSPF提供等价多路径。

通过提供区域/area路径,来提供额外的路径保护并可以减少协议所需要的流量。

此外,所有的OSPF路由信息交换都经过验证。

本备忘录与RFC 2178的不同,在附录G中说明。

所有的不同点都实现向后兼容。

按本备忘录的实现,与按照RFC2178、1583、1247的实现能够协同运作。

OSPF是一种典型的内部网关协议/Interior Gateway Protocol (IGP)。

这意味着其路由信息是描述属于同一个自制系统/Autonomous System (AS)中的路由器。

OSPF协议是基于连接状态或被称为SPF的技术,这与传统TCP/IP网际路由协议所使用的Bellman-Ford(一种算法)技术不同。

OSPF协议是由Internet Engineering Task Force的OSPF工作组所开发的,特别为TCP/IP网络而设计,包括明确的支持CIDR和标记来源于外部的路由信息。

OSPF也提供了对路由更新的验证,并在发送/接收更新时使用IP多播。

此外,还作了很多的工作使得协议仅用很少的路由流量就可以快速地响应拓扑改变。

1.1. 协议概述OSPF仅通过在IP包头中的目标地址来转发IP包。

IP包在AS中被转发,而没有被其他协议再次封装。

OSPF是一种动态路由协议,它可以快速地探知AS中拓扑的改变(例如路由器接口的失效),并在一段时间的收敛后计算出无环路的新路径。

收敛的时间很短且只使用很小的路由流量。

在连接状态路由协议中,每台路由器都维持着一个数据库以描述AS的拓扑结构。

这个数据库被称为连接状态数据库,所有参与的路由器都有着同样的数据库。

数据库中的各项说明了特定路由器自身的状态(如该路由器的可用接口和可以到达的邻居)。

该路由器通过洪泛/flooding将其自身的状态传送到整个AS中。

所有的路由器同步地运行完全相同的算法。

根据连接状态数据库,每台路由器构建出一棵以其自身为树根的最短路径树。

最短路径树给出了到达AS中各个目标的路径,路由信息的起源在树中表现为树叶。

当有多条等价的路径到达同一目标时,数据流量将在这些路径上平均分摊。

路径的距离值表现为一个无量纲数。

OSPF允许将一些网络组合到一起。

这样的组被称为区域/area。

区域对AS中的其他部分隐藏其内部的拓扑结构,信息的隐藏极大地减少了路由流量。

同时,区域内的路由仅由区域自身的拓扑来决定,这可使区域抵御错误的路由信息。

区域通常是一个子网化了的IP网络。

OSPF允许灵活的配置IP子网。

由OSPF发布的每条路径都包含目标和掩码。

同一个IP网络的两个子网可以有不同的大小(即不同的掩码),这常被称为变长子网/variable length subnetting。

数据包按照最佳匹配(最长匹配)来转发。

主机路径被看作掩码为“全1”(0xffffffff)的子网来处理。

OSPF协议中所有的信息交换都经过验证。

这意味着,在AS中只有被信任的路由器才能参与路由。

有多种验证方法可以被选择。

事实上,可以为每个IP子网选用不同的验证方法。

来源于外部的路由信息(如路由器从诸如BGP[引用23]的外部网关协议中得到的路径)向整个AS内部宣告。

外部数据与OSPF协议的连接状态数据相对独立。

每条外部路径可以由所宣告的路由器作出标记,在自制系统边界路由器(ASBR)之间传递额外的信息。

1.2. 常用术语的定义本节定义了贯穿本文的,在OSPF协议中有特定含义的术语。

对IP协议不熟悉的读者可使用[引用13]作为IP协议的绪论。

路由器/Router:一种三层IP包的交换设备。

在早期的IP文献中被称为网关/gateway。

自制系统/Autonomous System:一组使用相同路由协议交换路由信息的路由器,缩写为AS。

内部网关协议/Interior Gateway Protocol:被一个AS内的路由器所使用的路由协议,缩写为IGP。

每个AS使用单一的IGP,不同的AS会使用不同的IGP。

路由器标识/Router ID:一个32位的数字,用以识别每台运行OSPF协议的路由器。

在一个AS中,这个数字可以唯一地表示出一台路由器。

网络/Network:在本备忘录中,会表示IP网络/子网/超网。

一个物理网络上可能设置有多个网络/子网号,我们把它们按照独立的网络来对待。

物理点对点/point-to-point网络是个例外--无论在上面设置了多少网络/子网号(如果有的话),都将其看作是一个网络。

网络掩码/Network mask:一个32位的数字,表示IP地址的范围来说明这是一个IP网络/子网/超网。

本文以16进制来表示网络掩码。

如将C类IP地址的网络掩码显示为0xffffff00,这一掩码在其他文献中经常被表示为255.255.255.0。

点对点网络/Point-to-point networks:仅仅连接一对路由器的网络。
