  1. NS2 - Appendix Ming-Feng Yang

  2. Outline • NS2 Models • NS2 Directory Structure • Extending NS2 in OTcl • Extending NS2 in C++ • NS2 related links

  3. NS2 Models • Traffic models and applications • Web, FTP, telnet, CBR, real audio • Transport protocols • unicast: TCP (Reno, Vegas, etc.), UDP • Multicast: SRM • Routing and queueing • Wired routing, ad hoc routing and directed diffusion • queueing protocols: RED, drop-tail, etc • Physical media • Wired (point-to-point, LANs), wireless (multiple propagation models), satellite

  4. NS2 Directory Structure ns-allinone Tcl8.0 TK8.0 OTcl tclcl ns-2 nam-1 C++ code ... tcl ex test mcast lib ... examples validation tests OTcl code

  5. Extending NS2 in OTcl • If you don’t want to compile • Source your changes in your sim scripts • Otherwise • Modifying code; recompile • Adding new files (ex. tcl/mysrc/msg.tcl) • Change Makefile • NS_TCL_LIB = \ tcl/mysrc/msg.tcl \ ….. • Change tcl/lib/ns-lib.tcl • Class Simulator source ../mysrc/msg.tcl ….. • Recompile

  6. Extending NS2 in C++ • Modifying code • Make depend • Recompile • Adding code in new files • Change Makefile (include “new files.o” in the object file list) • Make depend • Recompile
