Boson NetSim模拟器
Boson NetSim模拟器发表时间：2007/10/26由于交换机和路由器的价格昂贵，型号繁多，我们不可能为了学习它而自己购置设备。
模拟器软件可以在个人计算机上模拟交换机、路由器的配置过程，使我们足不出户就可以完成交换机和路由器的配置实验，是学习交换机和路由器的常用方法。
以下我们介绍一种基于Cisco公司的Catalyst系列交换机和Cisco系列路由器的模拟器软件Boson Netsim的使用。
一、Boson模拟器的安装下载地址：Boson Netsim 5.31。
下载后运行其中的boson netsim 5.31.exe把Boson安装在本机中。
软件注册：运行boson netsim，然后选择菜单上的Ordering，选择修复KE Y，将出现的序列号复制。
运行注册机BosonKeyGen.exe，把序列号粘贴至“PAS T HERE”，下面就会出现你想要的KEY。
再把这个KEY添回boson netsim中，就可完成注册。
需要注意的是如果本机没有安装Microsoft forms2.0(大部分Windows 2000以上的操作系统都有该组件)和Adobe Acrobat程序(查看PDF文件的程序)，Bos on是不能启动的。
Boson有三部分构成：Boson netsim、Boson Network Designer和Lab Navi gator。
二、Boson netsimBoson netsim就是模拟器，所有的实验都是在Boson netsim中完成的。
双击桌面上的“Boson netsim”图标就可以启动Boson netsim，其界面如图1所示。
图1在Boson netsim的主界面中是当前设备的命令行界面，它可以用工具栏中的按钮进行切换：eRouters工具用来选择路由器；eSwitches工具用来选择交换机；eStations工具用来选择客户机。
在配置时应该是配置哪台设备就选出哪台设备。
Network-Emulator-Toolkit模拟各种网络环境windows
Network-Emulator-Toolkit模拟各种⽹络环境windows1. 背景、⽬标、⽬的(1) 背景：我们在使⽤⽹络时，时常遇到在正常⽹络环境下的代码运⾏⼀切正常，可以复杂的⽹络环境下的各种问题⽆法复现，必须搭建模拟各种⽹络环境，去复现问题，定位问题。
不管是移动平台，还是pc 端； ios XCode已经具备此功能， Android设备，及 windows 平台还是需要我们⾃⼰搭建。
(2) ⽬的：通过Network-Emulator-Toolkit 配置控制⽹络条件，满⾜包括下⾏速度、下⾏丢包率、下⾏延迟、上⾏速度、上⾏丢包率、上⾏延迟、DNS 延迟的设置、以及可抓包。
(3) ⽬标：模拟复杂可复⽤的⽹络环境，复现，定位问题2. ⽅案⽅案可以是1 wireshark、Fiddler、Charles等抓包⼯具提供代理、2.模拟器、3. Network Link Conditioner + 共享 wifi。
本⽂肯定是采⽤ 3，要不标题就错了；介绍⼀款windows下的⽹络模拟器，可以模拟各种丢包或延迟的⽹络（Network Emulator for Windows Toolkit）这⾥简单介绍⼀下使⽤⽅法：软件界⾯：No Loss：默认，不模拟丢包。
Periodic loss: 模拟周期性的丢包。
按填写数量(设为x个)，每x个包，就丢⼀个包(one packet is dropped per given number of packets)。
Random loss: 模拟随机丢包，按给定丢包的概率，随机丢包。
Burst loss: 模拟根据给定的可能性进⾏丢包。
当发⽣⼀个丢包事件时，接着连续丢⼏个包（丢包数量控制在最⼤(max)最⼩值(min)之间）。
G-E loss: 模拟发⽣数据包丢失遵循Gilbert-Elliot模型，由两个状态组成：好的状态和坏的状态。
可分别为这2个状态指定数据包丢失率,同时可设置⽹络传输在这两种状态的概率（And the network transit between the two states is at given transition probabilities）Error说明：真实世界中，当数据包经过⽹络传输时，包中的⼀到多个字节(bit)数据可能发⽣错误。

PS模拟器教程
PS 模拟器使用说明使用ePSXe 1.52 中文版该版是一个修正版，修复了以前版本中存在的一些错误，并去掉了一些没用的功能选项。
中文版做了比较全面的汉化，比前两个版本做得都要好，DOS 窗口的运行信息也汉化了，模拟器运行出问题时，你不妨从这里找一下提示。
另外，模拟器里带有一套比较优秀的插件，全部都是最新版，也都做了全面的汉化。
为了照顾一些新玩家，游戏光盘中放了“素食者”所做的新手教程，如果你是第一次用这个模拟器不妨参考一下。
PS游戏使用说明1．请先安装tool里的deamontool虚拟光驱和vgs1。
4的ps模拟器2．玩游戏时，请先将游戏rom解压缩到硬盘，解完后应为bin文件或iso文件3．用deamontool虚拟bin或iso （选择虚拟文件时，请把查找文件类型改为all files，不然将无法找到bin）4．用vgs开始游戏PS游戏运行说明1．文件解压缩后为，执行*.EXE文件，会产生一个*.iso文件。
2．使用虚拟光驱软件的软件DAEMONTools中文版读取.iso或.cue,再用VGS1.41中文版进行模拟。
（此法只适于Win98）3．也可用ePSXe直接执行RUN/ISO读取模拟游戏，内附详细图文教程。
PS游戏模拟器使用方法虚拟光驱盘符必须是在所有物理光驱的前面。
在模拟游戏时，开始如果遇到出现”完全模拟“字出现，或不断读硬盘，但是不出画面的情况。
这事电脑硬件和模拟器兼容的问题，不要认为死机了，只要按键盘“ESC”就能退出，然后需要重新启动模拟器，然后在启动游戏瞬间（动画播放前夕）不断的按执行游戏的按钮（如果有游戏手柄一般设定为START；如果是用键盘操作，根据玩家自己设定）,如果听到“铛”的声音就表示成功了，就能跳过画面重复读取不出画面的情况。
ZIP文件解压缩后为一.exe可执行文件，执行此.exe文件可生成一.iso文件或.bin文件（可将.bin扩展名直接重命名为.iso），可直接用ePSXe读取进行游戏，或是用虚拟光驱DAEMON 读取再用VGS1.4中文版/VGS1.41(尽量使用此版本，有些版本无法读取）进行游戏。

进入主界面后同时运行了Boson netsim和Boson lab navigator，Lab navigator是软件内置的一些实验拓扑图，部分正确的配置文件。
包括cisco培训课程的CCNA，BCRAN，BSCI及一些定制的实验。
如果按照cisco的教材来学习，这些内置的实验能更好地按照cisco的课程进度来联系。
Boson netsim运行的界面如图：工具栏的前三个按钮用于快速切换要配置的设备（路由，交换，PC机），第四个按钮用于打开lab navigator，第五个用于查看当前使用的拓扑图，第六个用于打开远程控制面版，等于是使用Telnet登录远程远程的设备来调试。
菜单栏主要包括了文件菜单，模式菜单，设备菜单，工具菜单，注册工具，窗口布局工具和帮助。
其中文件菜单包括：✓新建：调用拓扑图设计软件重新绘制一个新拓扑✓装入拓扑图：加载一个之前做好的拓扑图文件✓粘贴配置文件：粘贴一个来自真实路由器或者交换机的配置文件✓装入单个设备配置文件（合并）：将以前保存的单个设备配置文件装入到当前实验环境中，以合并方式进行✓装入单个设备配置文件（覆盖）：将以前保存的单个设备配置文件装入到当前实验环境中，以覆盖方式进行✓装入多个设备文件配置文件：将以前保存的所有设备配置文件装入到当前实验环境中✓保存单设备配置文件：将当前设备的配置文件存盘（保存在硬盘上备下次需要时使用，扩展名是rtr）✓保存所有设备配置文件：将当前拓扑图中所有设备的配置存盘✓打印：打印当前拓扑图✓退出：退出Boson netsim for ccnp模式菜单包括：初级模式：以默认方式使用配置界面高级模式：以Telnet方式访问设备进行配置工具条：显示/隐藏“远程控制面版”设备菜单：选择使用哪个设备，作用相当于工具栏上的快速切换设备图标。
网络仿真软件的分析探讨
网络仿真软件的分析探讨范红艳，周彩根，樊昀北京邮电大学计算机科学与技术学院，北京 (100876)E-mail：fanicy@摘要：网络仿真是进行网络研究的重要方法，随着网络的发展，目前有多种网络仿真软件，不同的仿真软件适用于网络不同方面的研究，本文主要介绍了OPNET和NS2两种目前比较流行的仿真软件的特点及主要技术，然后针对一个实例比较了两种仿真软件的仿真效果。
关键词：网络仿真，仿真软件，OPNET，NS2中图分类号：TP 391.091.引言随着网络的快速发展，对于网络性能和新技术的研究也越来越重要，但是如果在现实网络中进行性能研究和新技术的设计开发，是不太现实的。
因此，网络仿真软件的出现大大提高了网络研究的效率，也减少了网络新技术开发的费用。
网络仿真是一种利用数学建模和统计分析的方法来模拟网络行为，从而获取特定的网络特性参数的技术。
网络仿真软件通过在计算机上建立一个虚拟的网络平台，来实现真实网络环境的模拟。
网络技术开发人员在这个平台上不仅可以对网络通信，网络设备，协议以及网络应用进行研究设计，还可以对网络的性能进行分析和评估。
本文接下来主要阐述了两种仿真软件的特点及主要技术，最后针对一个实例对两种仿真软件的仿真效果进行了比较。
2.网络仿真软件2.1 OPNET介绍OPNET是一种优秀的网络仿真和建模的工具，支持面向对象的建模方式，并提供图形化的编辑界面，更便于用户使用。
它强大的功能和全面性几乎可以模拟任何网络设备、支持各种网络技术，除了能够模拟固定通信模型外，OPNET的无线建模器还可用于建立分组无线网和卫星通信网的模型。
同时，OPNET在新网络的设计以及对现有网络的分析方面都有卓越表现。
它为通信协议和路由算法的研究提供与真实网络相同的环境。
此外，功能完善的结果分析器为网络性能的分析提供了有效又直观的工具。
OPNET的 Modeler是专门用于可视化原型设计的软件，它的使用既方便了网络模型的建立，又减少了编程的工作量。
在 VMware Workstation 配置UNetLab模拟器环境
在VMware Workstation 配置UNetLab模拟器环境必要条件：1.VMware Workstation要安装在系统中，版本至少是102.物理机器必须是支持虚拟设备的，否则无法安装unetlab，有的机器会在vmware部署中提示在bios下开启虚拟功能，详细操作请咨询机器厂家技术支持。
3.建议机器的配置为8G内存，硬盘大小怎么也得120G以上吧，太小也对不起部署环境吧，CPU最好是4核的，2核估计也能用。
4.物理机必须是联网的，没有网简直就是扯淡了。
启动VMware Workstation 10点击打开一个虚拟机，将下载好的Unified Networking Lab-1.0.0-8.ova的文件导入到Vmware中，以后叫什么根据官网，下载地址/download/#main点击import和accept基本算是初始工作好了编辑虚拟机的设置，修改一下内存4G（2G也行吧，不行再改，别超过物理内存，不然你一定疯了），4个CPU，网卡根据需要配置吧，默认的没改，下图是个参考，机器牛逼就配置成人家这样似的，不行也别太勉强了Virtualize IntelVT-x/EPT or AMD-V/RVI这个是必须的，物理机对虚拟化的支持必须的必，没有就先换个机器吧开动Unetlab 在vmware上，以后什么样不知道，现在是这样的配置unetlab开始，千万注意别瞎改，不然要重新来过，登录名root，密码unl进来后第一步就是改root密码，也别改的太简单可能过不去，我改的复杂一次就过了，两遍密码这是国际准则改主机名，这个就别改了，后面还要解IOU/IOL license,改了肯定会有影响接下来默认配置网络dhcp或者static都可以，我用的dhcp，实验的时候登录地址会变而已接下来默认配置继续默认配置基本完成了，自动重启系统重启后root登录输入apt-get updateapt-get -y upgrade#更新apt源保险起见，输入下面的命令安装一下更新的unetlab，上面的命令应该可以安装好，为了确认以及肯定再输一遍没坏处apt-get updateapt-get -y install unetlab到这的配置，unetlab的网页可以打开了，地址在登录root时有显示，打开浏览器访问试一下，没有问题，继续下面的部署，以下是官方支持的IOS或者虚拟设备可以大概看一下Dynamips (Cisco IOS emulation)c7200-adventerprisek9-mz.152-4.S6 (supported cards: PA-FE-TX,PA-4E, PA-8E)c3725-adventerprisek9-mz.124-15.T14 (supported cards: NM-1FE-TX, NM-16ESW)c1710-bk9no3r2sy-mz.124-23Other images from the above series should work tooIOL (IOS on Linux also known as IOU)L2-ADVENTERPRISE-M-15.1-20131216.binL2-ADVENTERPRISE-M-15.1-20140814.binL2-IPBASEK9-M-15.1-20130726.binL3-ADVENTERPRISEK9-M-15.4-1T.binL3-ADVENTERPRISEK9-M-15.4-2T.binL3-ADVIPSERVICES-M-15.1-2.9S.binAnd othersQemuCisco ASA 8.0.2 (Singe and Multi Context)Cisco ASA 8.4.2 (Support Multi Context)Cisco ASA 9.1.15 (Support Multi Context)Cisco ASAv (ver 9.3.2.200;

HP OpenView Network Node Manager 接口管理状态自动化指南说明书
Interface Managed-State Automation1. What is “Interface Managed-State Automation”?HP OpenView Network Node Manager (NNM) allows its users to control which objects in its database will be managed by NNM. You can select a network interface object belonging to a node and then use menu commands to tell NNM to either“manage”or“unmanage”that interface. If the interface is managed,NNM will poll that interface at a pre-configured interval to determine its current operational status. If the interface is unmanaged, NNM will not poll it.“Interface Managed-State Automation” lets you control the managed state for large numbers of interface objects in an automated manner. The feature is implemented by the ovautoifmgr command, which reads a configuration file containing your desired rules. These rules define the following conditions:•which nodes in the database should have their interfaces examined for their managed state.•which interfaces on these nodes should be managed or unmanaged, based upon the characteristics of the interface.•which interfaces on these nodes should be managed or unmanaged,based upon what type of node the interface is connected to.The rules make use of the NNM topologyfilter capability,which gives them significantflexibility. This allows the rules to be as simple or as complex as you need. Once the rules are set up, ovautoifmgr can apply them regularly to the managment environment, keeping it up to date as devices are added,deleted,or changed.It can help keep NNM running optimally with a minimum of your attention.The ovautoifmgr command runs through the configured rules, making any managed state adjustments as needed, and then terminates. It does not run continuously. This allows the command to be scheduled to run on a periodic basis using the NNM system’s scheduling capabilities (cron on Unix systems and the windows scheduler on Windows systems).It is also important to note that “Interface Managed-State Automation” is not a means for controlling the managed state of nodes.It only deals with interfaces contained within the nodes. Also, it is not a means for limiting the range of discovery. It will only operate upon interface objects which already exist within NNM’s database. For limiting discovery, NNM has alternate features such as discovery filters and the netmon.noDiscover file.By default, NNM maintains a managed state for all interfaces belonging to managed nodes. Therefore,in a large managed environment,NNM will spend a significant amount of time polling these interfaces to see if they are up or down. This can sap the resources of the management station, generate significant network traffic, and possibly overburden the managed devices. Depending upon your goals, there may be many network interfaces that do not need to be monitored with status polls.For example,a large network switch may have most of its interfaces connected to individual desktop computers, and these interfaces will go down whenever the desktop computer is turned off. If you are primarily concerned about whether the switch is up, and less concerned about the status of these interfaces to desktop systems, it would be helpful to unmanage most of the switch interfaces. The only ones that should remain managed would be those connected to the remainder of the network, possibly interfaces connected to important servers, and the interface that bears the IP address for the switch. Maintaining the managed state of all of these interfaces manually would be laborious,error prone,and tedious.The ovautoifmgr command can easily be configured once to apply this rule to all the switches in the managed environment, and can be rerun as often as you like.This offers several benefits:•you will only see status changes on important switch interfaces.•the NNM station will spend fewer CPU cycles checking status on unimportant interfaces.•a larger network environment can thus be managed than would otherwise be possible with the same NNM station hardware.•network management traffic will use less network bandwidth.There are some other reasons why you might consider unmanaging an interface.Perhaps there is a device where a status poll directed at one of its interfaces will interfere with its normal operation. It might be desirable to only allow status polling of the main interface for this device and prevent it on all of its other interfaces.Another case is in environments where not all IP addresses are reachable from the NNM station. If there is a router in this case where only one of its IP addresses is reachable by the NNM station, there are a couple of options to consider. If it is critical that status be maintained on all of its interfaces, then the netmon.snmpStatus file should be used. This would allow status to be maintained on all interfaces,but would cost more in CPU time(for both NNM station and router) and network bandwidth utilization. However, if you do not need status for all interfaces on this router, then it would be better to have all but one interface unmanaged. This can be done very easily with ovautoifmgr.The primary references for how to use ovautoifmgr are found in the following NNM references. On Unix systems, the following man pages should be consulted: ovautoifmgr(1m), ovautoifmgr.conf(4),and OVfilterIntro(5).On Windows systems,see the ovautoifmgr page in the Administrator’s Reference section, the ovautoifmgr.conf page in the File Formats section, and OVfilterIntro in the Concepts Reference section.In particular,the ovautoifmgr.conf page containsa number of examples that can be used as a starting point.4. Other factors to considerThis feature is intended to be used in environments where decisions about which interfaces to manage do not need to be made in real time.That is,if new interfaces get discovered and added to the database, that it should be acceptable to have them managed until the next time that ovautoifmgr is run.Likewise,if an unmanaged interface has its characteristics changed such that it now needs to be managed,it should be acceptable to wait until the next scheduled run of the tool for the change to happen.If there are nodes where interfaces are dynamically created and deleted (for example, with the making and breaking of dialup phone line connections), such interfaces will only be unmanaged by ovautoifmgr if they happen to exist at the time the tool is run. If that interface is later deleted and then re-added, it will again be in the managed state.The following types of interfaces never have their managed state adjusted by ovautoifmgr:•any interfaces contained within an unmanaged node.•interfaces created by NNM itself for the purpose of network layout. Such interfaces are not associated with real interfaces on the device, do not have an IP address, and are notstatus-polled by NNM.•interfaces which are discovered by a remote NNM Collection Station (CS). Only locally-discovered interfaces can be managed or unmanaged by ovautoifmgr. However, you can run it on the CS if you wish.The adjustment of the managed state of interfaces will only affect NNM’s polling of that node, and will not affect how NNM/Extended Topology handles such nodes. Extended Topology is only affected by the managed state of a node object, and not the state of its interface objects. You should not use ovautoifmgr to unmanage all IP interfaces on a node. This could prevent NNM from successfully using SNMP to learn of changes to the node that would otherwise cause interfaces to become managed again. For network switch or repeater devices, which normally only have one IP interface associated with them,you should only use the tool to adjust the non-IP interfaces,and leave the IP address alone(and managed).For routers,which normally have many IP addresses, you should leave at least one reliably accessible IP address managed. Unmanaging an interface will not affect the ability of NNM to accomplish network layout tasks. Even though ovautoifmgr may choose to unmanage an interface associated with a switch port,forinstance,NNM will still be able to detect changes in what is connected to that switch port and will show such changes on the map.When first implementing the ovautoifmgr feature within a management environment, it is likely that there will be many interfaces which need to have their managed state changed, while subsequent runs of the tool will probably only find a few changes to be made. When a large number of status changes need to be made, this can cause a large number of NNM events to be generated in a very short amount of time.Be aware that such aflood of events can cause NNM to become temporarily unresponsive, as these events will keep it very busy. As a result, you should plan a time when NNM responsiveness is not as important to perform this task for the first time. To reduce the load on the system during this operation, you could temporarily disable any Event Correlation System circuits, and close any open ovw maps.If NNM is being used in a distributed management environment where multiple NNM systems are communicating with each other, you should use the ovautoifmgr tool on each remote collection station(CS)to control that station’s polling behavior.The status of each interface is propagated to the central Management Station (MS) as determined by its managing CS. If multiple CSs are managing the same interface, then whichever CS is considered the primary CS for that object is the one whose status is displayed on the MS.If ovautoifmgr is also being used on the MS,it only affects the status of interfaces that are directly polled from the MS. It does not affect how interfaces on a remote CS are managed. See “Guide to Scalability and Distribution” for more details on distributed management, and the meaning of primary collection stations.It is possible to have more than one configuration file for ovautoifmgr. While a single invocation of the command uses only one configuration file, the command can be run at different times with different configurationfiles.Below are some cases that illustrate how you could use this approach.Suppose you want to adjust the managed state of router interfaces only on one day of the week, and network switches on a different day. You can achieve this by having one configuration file that details the rules related to routers,and another one detailing rules related to the switches.The scheduling tool, then, would start ovautoifmgr with a different -f option on different days.Or suppose you want to have certain interfaces managed during the day, but unmanaged during the night.Two configurationfiles could be set up such that one manages these interfaces,and the other unmanages them. The two invocations of ovautoifmgr would then specify the appropriate configuration file with the -f option. Note, however, that this type of configuration will generate large floods of events on each run. See the comments above related to event floods.Finally, you could use multiple configuration files to partition a large number of interfaces into smaller groups, so that their adjustment could be spread out over time. This is one way to avoid large event floods that interfere with NNM operation for long periods of time.5. TroubleshootingWhen setting up ovautoifmgr to run regularly, you should do a trial run with the proposedconfiguration directly from the command line, and then observe its behavior. The -v options can be turned on, so that the log file will contain information that can be studied to determine correct operation.When the ovautoifmgr command detects an error condition,it reports this error both in the logfile and on the stderr output from the program. However, it is very possible for the command to not detect any errors and yet not perform as you intended. This is why you should use the verbose options while diagnosing its behavior.There are three levels of verbosity of logging, in addition to the default (which is “errors only”). They are controlled by how many times the v flag appears on the command line.-v program phases are noted, along with final statistics. No node or interface information.-vv same as -v, plus logging of each node that is processed.-vvv same as -vv, plus logging of each interface that is processed.When very detailed logging is needed, and the managed environment is large, the amount of log output can get very large. Since the log file size is limited, older information may be lost. Therefore, for debugging purposes, it is good to set the size of the log file to be very large, and perhaps put the log file on a disk volume that has sufficient space to hold all the data. See the ovautoifmgr man page (or reference page) for more information on how to do this.In the log output,specific nodes and interfaces are identified by numbers.These numbers are the NNM object identifiers. More details on these objects can be found from the NNM databases by using the ovtopodump or ovobjprint commands giving them the object identifier.If a certain node or interface appears to have not been properly processed, use ovtopodump with the node name to find the node and interface object identfiers. Then you can see where these numbers are referenced in the log file and see what decisions were made.There are some cases in the log file and in ovtopodump output where a UUID is used rather than the NNM object ID. The UUID is a long, multi-character string that looks like this:90553e90-27e6-71d7-184c-010*********You can use the UUID as a parameter to ovtopodump to see what object it refers to,including name and NNM id number.Also bear in mind that the log file is cumulative. It may contain output from several runs of ovautoifmgr. When debugging, it is good to use a new log file for each run.。

什么是HP_Network_Simulator
HP_Network_Simulator:惠普网络模拟器，基于X86的架构在， Windows和Ubuntu两种常用桌面操作系统上运行。 2010年4月12日，惠普收购了H3C(全线路由器和以太网交换 机产品)。原有配置指令不变，实际上HP_Network_Simulator 就是H3C模拟器。该模拟器是基于基于VirtualBox运行。搭建环 境是通过特定的语法去配置，包括设备参数和连接参数。
