第一部分：仿真工具的特性
1.1 High-Fidelity Simulation Results
NCTUns directly uses the real-life Linux’s TCP/IP protocol stack to generate high-fidelity simulation results
1.2 Reusing All Real-Life Application Programs
In NCTUns, all real-life existing or to-be-developed UNIX application programs (e.g., the P2P BitTorrent application) can be run up on a node in a simulated network.
1.3 ▲Seamless Integration of Emulation and Simulation
In an emulation, nodes in a simulated network can exchange real packets with real-world machines via the simulated network. That is, the simulated network is seamlessly integrated with the real-life network so that simulated nodes and real-life nodes can exchange their packets across the integrated simulated and real-life networks.
1.4 High Simulation Speeds and Repeatable Simulation Results
1.5 Support for Various Important Networks
It simulates IEEE 802.11(a)(b) wireless LAN networks, including both the ad-hoc and infrastructure modes.
It simulates GPRS cellular networks.
It simulates optical networks.
It simulates IEEE 802.11(b) wireless mesh networks, IEEE 802.11(e) QoS networks,
It simulates 802.16(d) WiMAX networks, including the PMP and mesh modes.
It simulates 802.16(e) mobile WiMAX PMP networks.
It simulates 802.16(j) transparent mode and non-transparent mode relay WiMAX networks.
It simulates the DVB-RCS satellite networks for a GEO satellite located 36,000 Km above the earth.
It simulates 802.11(p)/1609 vehicular networks, which is an amendment to the 802.11-2007 standard for highly mobile environment.
Over this platform, one can easily develop and evaluate advanced V2V (vehicle-to-vehicle) and V2I (vehicle-to-infrastructure) applications in the ITS
(Intelligent Transportation Systems) research field.
1.6 Support for Various Network Protocols
NCTUns simulates various protocols such as IEEE 802.3 CSMA/CD MAC, IEEE 802.11 (a)(b)(e)(p) CSMA/CA MAC, the learning bridge protocol used by switches, the spanning tree protocol used by switches, IP, Mobile IP, RIP,OSPF, UDP, TCP, HTTP, FTP, Telnet, etc. It simulates the DiffServ QoS protocol suite, the optical light-path setup protocol, the RTP/RTCP/SDP protocol suite. It simulates the IEEE 802.16(d)(e)(j) WiMAX PMP protocol suites and the 802.16(d) mesh mode protocol suite. It simulates the DVBRCST protocol suite.
1.7 Highly-Integrated and Professional GUI Environment
1.8 Open-System Architecture
A protocol module developer can easily implement his (her) own protocol and integrate it into the simulation engine.
Details about adding a new protocol module to the simulation engine are presented in the “The Protocol Developer Manual “
1.9 Distributed Architecture for Remote and Concurrent Simulations
Because the components of NCTUns use Inter-Process Communication (IPC, that is, sockets) to communicate, they can also be run on the same machine. (This is called the “single-machine” mode.).
第二部分：安装Fedora
1.1 安装Fedora-12-i386-DVD.iso
（注：不要用Fedora-12-x86_64，这个会出现很多错误）
Basic video install(第二行选项进行安装)
磁盘采用Create Custom Layout进行手动分区，采用磁盘格式时均默认，各个分区的大小如下

Important Notice!
If your X-window system adopts KDE as the default desktop manager program, please BE SURE to upgrade your KDE version to 4.0.5 or higher. It is found that KDE 4.0.3 is likely to trigger unexpected signals to the NCTUns simulation engine, which may cause the simulation engine to run abnormally.
Besides, we suggest to upgrade the OpenGL library into the newest version because of the display of the GUI. If you have a video card equipped on your machine, please find the latest driver for your video card.
To upgrade KDE and OpenGL libraries, you can use the following command:
yum update
Although this command will update all programs contained in Fedora 11 (including KDE, OpenGL libraries) and thus may take a long time, it is the easiest way to upgrade KDE. If you just upgrade KDE, some dependency problems may result. |
1.3 安装后重启系统，选择NCTUns内核（登陆界面会多了一个nctuns用户，它的密码是nctuns）
1.4 重启进入系统后，设置环境变量
$ gedit .bashrc
在里面加入下面3行export NCTUNSHOME=/usr/local/nctuns
export NCTUNS_BIN=/usr/local/nctuns/bin
export NCTUNS_TOOLS=/usr/local/nctuns/tools
export LD_LIBRARY_PATH=/usr/local/nctuns/lib
重启系统
或者执行下句使它生效
#source .bashrc
1.5 运行
打开命令行Terminal，切换到root
#/usr/local/nctuns/bin/dispatcher
再打开另一个命令行Terminal，切换到root
#/usr/local/nctuns/bin/coordinator
最后再打开一个新的命令行Terminal（GUI用户不能以root登录）
~/usr/local/nctuns/bin/nctunsclient
成功运行后会出现如下的GUI界面。
1.5.1 注意1
运行/usr/local/nctuns/bin/nctunsclient，如果出现以下错误：
/usr/local/nctuns/bin/nctunsclient.bin: error while loading shared libraries:
libqt-mt.so.3: cannot open shared object file: No such file or directory
下载qt3-3.3.8b-28.fc12.i686.rpm后安装。
1.5.2 注意2
/usr/local/nctuns/bin/nctunsclient，若提示：
Session management error:None of the authentication protocols specified are supported.
原因可能是以root身份运行（不要用root身份运行nctunsclient），或者网卡没连接上网络，或者运行nctunsclient之前没有先启动dispatcher、coordinator。
