说明:  click实现软件路由器,编辑网络协议。一个完整的路由协议需要完成的功能包含以下内容:制定指导数据报文分组从一个网络到另一个网络的规定和标准;创建路由表,并维护网络拓扑结构;运行路由协议,执行路由选择和分组转发功能。这对我们接下来的协议设计提出了基本的要求,即对于网络中的每一层都需要定义报文的格式,然后对于报文在网络中的发送、接收和转发都有稳定的拓扑结构。

THE CLICK MODULAR ROUTER RELEASE 2.0.1 ====================================== This is the README file for the source release for the Click modular software router. More recent information may be available on the Web at http://www.read.cs.ucla.edu/click/ Click is a modular router toolkit. To use it you'll need to know how to compile and install the software, how to write router configurations, and how to write new elements. Our ACM Transactions on Computer Systems paper, available from the Web site, will give you a feeling for what Click can do. Using the optimization tools under CLICKDIR/tools, you can get even better performance than that paper describes.

User documentation is in the 'doc' subdirectory. This directory contains manual pages for the Click language, the Linux kernel module, and several tools; it also has a script that generates manual pages for many of the elements distributed in this package. To install these manual pages so you can read them, follow the 'INSTALL' instructions, but 'make install-man' instead of 'make install'. RUNNING A CLICK ROUTER ---------------------- Before playing with a Click router, you should get familiar with the Click configuration language. You use this to tell Click how to process packets. The language describes a graph of "elements", or packet processing modules. See the 'doc/click.5' manual page for a detailed description, or check the 'conf' directory for some simple examples. Click can be compiled as a user-level program or as a kernel module for Linux. Either driver can receive and send packets; the kernel module directly interacts with device drivers, while the user-level driver uses packet sockets (on Linux) or the pcap library (everywhere else). User-Level Program .................. Run the user-level program by giving it the name of a configuration file: 'click CONFIGFILE'. Linux Kernel Module ................... You must patch your Linux kernel first. See 'INSTALL' for more information. See the 'doc/click.o.8' manual page for a detailed description. To summarize, install a configuration by running 'click-install CONFIGFILE'. This will also install the kernel module if necessary and report any errors to standard error. (You must run 'make install' before 'click-install' will work.) NS-3 Simulator .............. See 'INSTALL' for more information on how to enable the NS-3 Click Integration. Further information on ns-3-click is available in the ns-3 manual: http://www.nsnam.org/docs/models/index.html#document-click NS-2 Simulator .............. See 'INSTALL' for more information. Once a Click-enabled version of NS-2 is installed, the 'ns' command is able to run Click scripts as part of a normal NS-2 simulation. Configurations .............. A few configurations are included in the 'conf' directory, including a Perl script that generated the IP router configurations used in our TOCS paper ('conf/make-ip-conf.pl') and a set of patterns for the Click pattern optimizer, click-xform ('conf/ip.clickpat'). Please check back to our Web site for more up-to-date configurations. ADDING YOUR OWN ELEMENTS ------------------------ Please see the FAQ in this directory to learn how to add elements to Click. COPYRIGHT AND LICENSE --------------------- Most of Click is distributed under a version of the "MIT License", which is a BSD-like license. See the 'LICENSE' file for details.

Element code that uses only Click's interfaces will *not* be derived from the Linux kernel, so the BSD-like 'LICENSE' will apply, not the GPL or the LGPL. BUGS, QUESTIONS, ETC. --------------------- We welcome bug reports, questions, comments, code, whatever you'd like to give us. We also have a mailing list for software announcements, and an anonymous Git repository (also accessible via CVS) where you can access our latest source code.
