Distributive Interactive Simulation (DIS) requires a communication architecture to support large scale simulations (100,000 entities). The communication architecture requirements for DIS are now being defined. DIS will require a wide area network that supports high data rates, multicasting and low latency. DoD can no longer afford unique solutions for the their wide area networking needs and must align their service requirements with the services provided by common carriers. An analysis is presented on how the future Broadband Integrated Services Digital Network(B-ISDN) and its technology standard, Asynchronous Transfer Mode (ATM), could help meet the WAN communication architecture requirements of DIS. The requirements of DIS are presented and mapped into a format compatible with international standards for common carrier services. Quality of Services (QoS) parameter values for DIS information types are estimated and compared to those of B-ISDN, Conclusions reveal that B-ISDN and its underlying technology, ATM, will help meet the DIS WAN communication architecture needs. Also, QoS parameter values for DIS require further definition and specificity to enable DoD to take advantage of the future common carrier services. DoD needs to define its future application requirements that are compatible with common carrier services
