PLM</A></H1><A NAME="sec:PLM"></A>This chapter describes the ns implementation of the PLM protocol[<A HREF="node589.html#legout_sigmetrics2000" tppabs="http://www.isi.edu/nsnam/ns/doc/node589.html#legout_sigmetrics2000">20</A>]. The code of the PLM protocol is written in both C++ and OTcl. The PLM Packet Pair generator iswritten in C++ and the PLM core machinery is written in OTcl. The chapter has simplythree parts: the first part shows how to create and configure a PLM session; thesecond part describes the Packet Pair source generator; the third part describesthe architecture and internals of the PLM protocol. In this last part, ratherthan giving a list of procedures and functions, we introduce the mainprocedures per functionality (instantiation of a PLM source, instantiation of aPLM receiver, reception of a packet, detection of a loss, etc.).<P>The procedures, functions, and variables described in this chapter can be found in:plm/cbr-traffic-PP.cc, plm/loss-monitor-plm.cc, tcl/plm/plm.tcl,tcl/plm/plm-ns.tcl, tcl/plm/plm-topo.tcl, tcl/lib/ns-default.tcl.<P><BR><HR><!--Table of Child-Links--><A NAME="CHILD_LINKS"><STRONG>Subsections</STRONG></A><UL><LI><A NAME="tex2html8429" HREF="node460.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node460.html">34.1 Configuration</A><UL><LI><A NAME="tex2html8430" HREF="node461.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node461.html">34.1.0.0.1 Creating a simple scenario with one PLM flow (only one receiver)<BR></A></UL><BR><LI><A NAME="tex2html8431" HREF="node462.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node462.html">34.2 The Packet Pair Source Generator</A><LI><A NAME="tex2html8432" HREF="node463.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node463.html">34.3 Architecture of the PLM Protocol</A><UL><LI><A NAME="tex2html8433" HREF="node464.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node464.html">34.3.1 Instantiation of a PLM Source</A><LI><A NAME="tex2html8434" HREF="node465.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node465.html">34.3.2 Instantiation of a PLM Receiver</A><LI><A NAME="tex2html8435" HREF="node466.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node466.html">34.3.3 Reception of a Packet</A><LI><A NAME="tex2html8436" HREF="node467.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node467.html">34.3.4 Detection of a Loss</A><LI><A NAME="tex2html8437" HREF="node468.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node468.html">34.3.5 Joining or Leaving a Layer</A></UL><BR><LI><A NAME="tex2html8438" HREF="node469.html" tppabs="http://www.isi.edu/nsnam/ns/doc/node469.html">34.4 Commands at a Glance</A></UL><!--End of Table of Child-Links--><BR><HR><ADDRESS>2003-09-23</ADDRESS></BODY></HTML>⌨️ 快捷键说明
