Overview of protocol testing programs, methodologies, and standards

The twin developments of sophisticated communications protocols and a multivendor environment are revolutionizing the world of data communications and telephony. Protocol testing will have a significant role in this evolving environment, for it helps ensure interoperability between and among systems from multiple vendors and service providers. AT&T, in its role of service and product provider, has a keen interest in protocol testing to ensure the interoperability of its products and services, alone and in concert with those of other vendors.
