To get around this limitation, each multihomed node is actually made up of more than one node. As shown in Figure <A HREF="node406.html#fig:multihomedNode" tppabs="http://www.isi.edu/nsnam/ns/doc/node406.html#fig:multihomedNode">32.1</A>, a multihomed node has a "core node" and an "interface node" for each simulated interface. The SCTP agent resides on all these nodes, but traffic only goes to and from the interface nodes. The core node is used for routing and is connected to each interface node via a uni-directional link towards the interface node, but traffic does not traverse these links. Instead, these links are used to dynamically determine which outgoing interface node to use for sending to a particular destination. Note: the user must configure multihomed nodes using commands in Section <A HREF="node409.html#sec:sctpCommands" tppabs="http://www.isi.edu/nsnam/ns/doc/node409.html#sec:sctpCommands">32.1.2</A> (an example is shown in Section <A HREF="node426.html#sec:multihomedExample" tppabs="http://www.isi.edu/nsnam/ns/doc/node426.html#sec:multihomedExample">32.5.2</A>).<P><DIV ALIGN="CENTER"><A NAME="fig:multihomedNode"></A><A NAME="14109"></A><TABLE><CAPTION ALIGN="BOTTOM"><STRONG>Figure 32.1:</STRONG>Example of a Multihomed Node</CAPTION><TR><TD><DIV ALIGN="CENTER">.3sctp-multihomedNode</DIV></TD></TR></TABLE></DIV><P><HR><!--Navigation Panel--><A NAME="tex2html7640" HREF="node407.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node407.html"><IMG WIDTH="37" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="next" SRC="file:/usr/share/latex2html/icons/next.png"></A> <A NAME="tex2html7634" HREF="node403.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node403.html"><IMG WIDTH="26" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="up" SRC="file:/usr/share/latex2html/icons/up.png"></A> <A NAME="tex2html7628" HREF="node405.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node405.html"><IMG WIDTH="63" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="previous" SRC="file:/usr/share/latex2html/icons/prev.png"></A> <A NAME="tex2html7636" 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="tex2html7638" 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="tex2html7641" HREF="node407.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node407.html">32.1.0.0.4 Packet Number vs</A><B> Up:</B> <A NAME="tex2html7635" HREF="node403.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node403.html">32.1 The Base SCTP</A><B> Previous:</B> <A NAME="tex2html7629" HREF="node405.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node405.html">32.1.0.0.2 Association Shutdown</A>   <B> <A NAME="tex2html7637" HREF="node1.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node1.html">Contents</A></B>   <B> <A NAME="tex2html7639" 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
