This version of the NIST Switch software works with FreeBSD 3.3 and ALTQ 2.0 
along with RSVPD 4.2a4. In order to install, follow these steps:

1. Install FreeBSD 3.3 and ALTQ 2.0 on the machine.  You can obtain
FreeBSD 3.3 several different ways, including on CD-ROM, or from the
Walnut Creek site at http://www.cdrom.com.  ALTQ 2.0 is available from
the Sony site at ftp://ftp.csl.sony.co.jp/pub/kjc/.  Before you go any
farther, make sure you can build and boot new kernels!

Note: Yes, you do have to use the versions of FreeBSD and ALTQ indicated.

2. cd to /usr/src and copy sys-altq to sys-mpls
	cp -r sys-altq sys-mpls 

3. cd to sys-mpls and apply the patch "patch-mpls"
	patch -p < $PATCHDIR/patch-mpls

4. Modify the ALTQ kernel configuration under i386/conf if you wish.
Then in any case, configure and make the kernel

5. Copy the .h files from /usr/src/sys-mpls/net to /usr/include/net
and from /usr/src/sys-mpls/netinet to /usr/include /netinet

6. Make the label module
	cd /usr/src/sys-mpls/modules/label ; make clean; make depend; make ; 
	make install

7. Copy the altq.conf and label.conf in /etc

8. Make libaltq under rsvpd-kit-991103

9. Make rsvpd under rel4.2a4l/rsvpd and all utilities under rel4.2a4l/labeltest

10.Reboot the kernel, load the label module using 
	kldload label
