TMC's newest contributor is Jon Arnold. Jon is is one of the most methodical and knowledgeable people I know in the IP communications space and I have always admired him a great deal. TMC has worked with Jon for many years and now we are proud to say Jon has become a regular columnist.
Here is his first column titled What is a Service Provider?.
You can find Jon's columns here and Greg Galitzine has more on where you will see Jon at ITEXPO next week.
