Introdction
===========

QOSIP is a simulation model of a sizable IPmc/RSVP network using the Quality of Service 
Extensions to OSPF. It allows incestigateion of scaling characteristics of QOSPF protocol
in networks of significant size. The model was developed using the OPNET simulation 
package but could be ported to any discrete event simulation with procedures defined in 
the C language. 

From this webpage you can download the whole model code but the TCP module which is the 
unchanged OPNET library model. Both the IP module and the Fddi MAC module are modifications
of copyrighted OPNET library models which MIL3 gives us permission to post on the webpage. 
The OPNET license is required to download and use these models.



Status
======

This version 1.0 model code has some bugs in the multicast tree calculation. Now the new 
version code has fixed all the bugs we know. It works well for the multicast and resource
reservation service. The only regretful thing is that it takes long time to run the big 
network model.

Any bug reports are especially welcome.  Include information describing your system and 
how to reproduce the problem.  


Understanding this model 
========================

We post all model code on web. You can download the codes according to your need. But 
first recommended thing you should do is to download all the code and running our 
"DebugModel".

What should you get to run the "DebugModel"?
