NOTE: A Basic familiarity with ns architecture is recommended before making the
following changes. The ns-2 extensions for OBS  is currently an ongoing
development effort. Some of the components of the OBns is still undergoing development.
Any suggestions, bug-reports or changes is welcome.
Please check for further details at http://dawn.cs.umbc.edu

Section 1. Installing obs-ns-0.9a.

Step 1. Unzip the provided source in the "ns-allinone-2.26(or x)/ns-2.26" directory.
        Section 2 (see below) has a list of the files present in the distribution.

Step 2: Changes that need to be done to the existing ns-2 source

1. To introduce a new packet ptype namely PT_IPKT (refer to Marc Greis's tutorial on
   adding new packet/protocols etc.).
   (a) In the file "common/packet.h " add the following packet type PT_IPKT
       as shown below:

	enum packet_t {
		PT_TCP,
		PT_UDP,
        	......
		// insert new packet types here
 		PT_IPKT,
        	PT_NTYPE // This MUST be the LAST one
	};


	p_info() {
		name_[PT_TCP]= "tcp";
		name_[PT_UDP]= "udp";
                ...........
 		name_[PT_TFRC]= "tcpFriend";
		name_[PT_TFRC_ACK]= "tcpFriendCtl";
		.
		.
		.
                name_[PT_LMS_SETUP]="LMS_SETUP";
                name_[PT_IPKT]="IPKT";  // add this line for IPKT

                name_[PT_NTYPE]= "undefined";
        }

    (b) In the file tcl/lib/ns-packet.tcl add

    	foreach prot {
		AODV
		ARP
		.
		....
		IPinIP
		IPKT   // add the following line for IPKT
		IVS
		....
    	};
Other changes may be necessary.

Step 3: Changes to the ns-2 Makefile

	Add the following lines to the OBJ_CC tag as shown below
	OBJ_CC = \
	.
	.
	.
	.
        obs-0.9a/cpp/debug.o obs-0.9a/cpp/fiber-delay.o obs-0.9a/cpp/integrated_agent.o \
        obs-0.9a/cpp/classifier/classifier-base.o obs-0.9a/cpp/classifier/classifier-core.o \
        obs-0.9a/cpp/classifier/classifier-edge.o obs-0.9a/cpp/classifier/classifier-obs-port.o \
        obs-0.9a/cpp/scheduler/scheduler-group.o obs-0.9a/cpp/scheduler/lauc-scheduler.o \
        obs-0.9a/cpp/scheduler/Table.o obs-0.9a/cpp/common/stat-collector.o \
        $(OBJ_STL)

	Add the following lines to NS_TCL_LIB tag as shown below
	NS_TCL_LIB = \
	.
	.
	.
	obs-0.9a/tcl/lib/ns-obs-defaults.tcl \
        obs-0.9a/tcl/lib/ns-obs-lib.tcl \
        obs-0.9a/tcl/lib/ns-optic-link.tcl \
        $(NS_TCL_LIB_STL)



Step 4: Running the build.
        (i) Run make clean; make
