All initialization events will have the flag <TT>-t *</TT>. This tells nam that this event needs to be parsed before any animation has started. <DL><DT><STRONG>Version</STRONG></DT><DD>The following line define the nam version as required to visualize the given trace:<PRE>V -t <time> -v <version> -a <attr></PRE> Normally there is only one version string in a given tracefile, and it is usually the first line of the file.An example is the following:<PRE>V -t * -v 1.0a5 -a 0</PRE><P>The flag <TT>-v 1.0a5</TT> tells nam that this script requires a version of nam > 1.0a5. For more information on this event look at the file tcl/stats.tcl under the procedure nam_analysis.<P></DD><DT><STRONG>Wireless</STRONG></DT><DD>If you want to use wireless nodes in nam you need the wireless intialization event.<PRE>W -t * -x 600 -y 600</PRE><P>This gives nam the size of the layout for the wireless world. The -x value is the width and -y is height. For more information look at the file animator.tcl in the procedure infer-network-model.<P></DD><DT><STRONG>Hierarchy</STRONG></DT><DD>Hierarchical address information is defined by:<P><TT>A -t time -n levels -o address-space size -c mcastshift -a mcastmask -h nth level -m mask in nth level -s shift in nth level</TT><BR><P>This trace gives the details of hierarchy, if hierarchical addressing is being used for simulation. Flag <TT>-n <levels></TT> indicate the total number of hierarchical tiers, which is 1 for flat addressing, 2 for a 2-level hierarchy etc. Flag <TT>-o <address-space size></TT> denotes the total number of bits used for addressing. Flag <TT>-h <nth level></TT> specifies the level of the address hierarchy. Flag <TT>-m <mask></TT> and <TT>-s <shift></TT> describes the address mask and the bit shift of a given level in the address hierarchy, respectively. Here is an example of a trace for topology with 3 level hierachy:<PRE>A -t * -n 3 -p 0 -o 0xffffffff -c 31 -a 1A -t * -h 1 -m 1023 -s 22A -t * -h 2 -m 2047 -s 11A -t * -h 3 -m 2047 -s 0</PRE>Look at tcl/netModel.tcl under the nam_addressing procedure for more information.<P></DD><DT><STRONG>Color Table Entry</STRONG></DT><DD>A table of color entries can be built using:<BR><TT>c -t time -i color id -n color name</TT><BR>Nam allows one to associate color names withintegers. This is very useful in coloring packets. The flow id ofa packet is used to color the packet using the corresponding colortable entry color.Notice the color name should be one of the nameslisted in color database in X11 (/usr/X11/lib/rgb.txt). <P></DD></DL><P>In addition to the above node and link layout events are also included in the initialization section.<P><HR><!--Navigation Panel--><A NAME="tex2html10114" HREF="node565.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node565.html"><IMG WIDTH="37" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="next" SRC="file:/usr/share/latex2html/icons/next.png"></A> <A NAME="tex2html10108" HREF="node563.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node563.html"><IMG WIDTH="26" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="up" SRC="file:/usr/share/latex2html/icons/up.png"></A> <A NAME="tex2html10102" HREF="node563.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node563.html"><IMG WIDTH="63" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="previous" SRC="file:/usr/share/latex2html/icons/prev.png"></A> <A NAME="tex2html10110" HREF="node1.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node1.html"><IMG WIDTH="65" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="contents" SRC="file:/usr/share/latex2html/icons/contents.png"></A> <A NAME="tex2html10112" HREF="node590.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node590.html"><IMG WIDTH="43" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="index" SRC="file:/usr/share/latex2html/icons/index.png"></A> <BR><B> Next:</B> <A NAME="tex2html10115" HREF="node565.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node565.html">41.1.2 Nodes</A><B> Up:</B> <A NAME="tex2html10109" HREF="node563.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node563.html">41.1 Nam Trace Format</A><B> Previous:</B> <A NAME="tex2html10103" HREF="node563.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node563.html">41.1 Nam Trace Format</A>   <B> <A NAME="tex2html10111" HREF="node1.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node1.html">Contents</A></B>   <B> <A NAME="tex2html10113" HREF="node590.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node590.html">Index</A></B> <!--End of Navigation Panel--><ADDRESS>2003-09-23</ADDRESS></BODY></HTML>⌨️ 快捷键说明
