Cell Utilization Efficiency of Internet Protocol Traffic over Asynchronous Transfer Mode Networks

In the near future, large computer networks will be connection oriented, with at least the data link connectivity being provided by the Asynchronous Transfer Mode. (ATM) networks. However, these networks may have to communicate with the existing network which predominantly use Internet Protocol...
