The traceevent ''l'' creates two simplex links and other necessary setups, henceit looks to users identical to a duplex link. Link may have manycolors and it can change its color during animation. Queues areconstructed in nam between two nodes. Unlike link, nam queue isassociated to a simplex link. The trace event ``q'' only creates aqueue for a simplex link. In nam, queues are visualized as stackedpackets. Packets are stacked along a line, and the angle between theline and the horizontal line can be specified in the trace event ``q''.Commands to setup different animation attributes of a link are asfollows:<P><TT>$ns duplex-link-op attribute value</TT> <P>The <attribute> may be one of the following: orient, color, queuePos, label.Orient or the link orientation defines the angle between the link andhorizontal. The optional orientation values may be difined indegrees or by text like right (0), right-up (45), right-down (-45), left(180), left-up (135), left-down (-135), up (90), down (-90). The queuePosor position of queue is defined as the angle of the queue line withhorizontal. Examples for each attribute are given as following : <PRE>$ns duplex-link-op orient right ;# orientation is set as right. The order ;# in which links are created in nam ;# depends on calling order of this function.$ns duplex-link-op color "green"$ns duplex-link-op queuePos 0.5$ns duplex-link-op label "A"</PRE> <P><HR><!--Navigation Panel--><A NAME="tex2html10339" HREF="node581.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node581.html"><IMG WIDTH="37" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="next" SRC="file:/usr/share/latex2html/icons/next.png"></A> <A NAME="tex2html10333" HREF="node578.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node578.html"><IMG WIDTH="26" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="up" SRC="file:/usr/share/latex2html/icons/up.png"></A> <A NAME="tex2html10327" HREF="node579.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node579.html"><IMG WIDTH="63" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="previous" SRC="file:/usr/share/latex2html/icons/prev.png"></A> <A NAME="tex2html10335" 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="tex2html10337" 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="tex2html10340" HREF="node581.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node581.html">41.2.3 Agent and Features</A><B> Up:</B> <A NAME="tex2html10334" HREF="node578.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node578.html">41.2 Ns commands for</A><B> Previous:</B> <A NAME="tex2html10328" HREF="node579.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node579.html">41.2.1 Node</A>   <B> <A NAME="tex2html10336" HREF="node1.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node1.html">Contents</A></B>   <B> <A NAME="tex2html10338" 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
