Description of OPNET Usage at DCU  

1. Performance Analysis of CORBA-based IN Networks 

Contact: Conor McArdle (mcardlec@teltec.dcu.ie) 
This Ph.D. project involves the development of OPNET models for a CORBA-based IN network environment. These models are being used for the development and simulation of a number of object deployment, load control and load balancing strategies. Initial results from the OPNET simulation study are given in [McArdle2000] and more detailed results may be found in [McArdle2001].

2. Load Control for Multimedia-over-IP Networks 

Contact: Rob Brennan (brennanr@teltec.dcu.ie) 
The aim of this Ph.D. project is to investigate load control issues in Multimedia-over-IP networks that are based on ITU, IETF and other standards. OPNET is being used to carry out a number of simulation studies. Results obtained using OPNET for the study of SCTP Congestion Control are given in [Brennan2001]
