A volume in the IEEE Telecommunications Handbook Series, this book is the one-stop source for the formulas and tables needed to design dimension switching systems and networks. It covers frequently used traffic formulas such as Erlang B (including alternate routing and Neal-Wilkinson peaked traffic tables), Erlang C, Binomial, and Engset along with practical examples to demonstrate how each is used. Computer programs are provided for those who prefer to do their traffic engineering on a computer.
