I’m not sure what you are asking. I’ve conducted basic telecommunications research on and off for 30 years and co-authored 50 articles and 2 books related to traffic engineering. However, I have been unconnected to mainstream traffic engineering for 15 years. The VB6 based simulator also simulates outward traffic and switching and has a number of uniquely beneficial capabilities. I’d be glad to give it to anyone who can make use of it. Are you interested or know someone who is? jim.jewett@ehc.com or 615/344-6072 (Nashville, Tennessee USA).
