This article discusses various issues related to the alternative of Asynchronous Transfer Mode (ATM). ATM. was the brainchild of the international standards process. It was designed to allow for efficient packet multiplexing of traffic of any type while preserving control over quality of service. The foundation of ATM was the "cell." a little chunk of information 53 bytes long. If one listens closely in the next six months, one may hear the last gasp of ATM as a carrier technology. The question now is what ATM's successor will look like. While Ethernet and IP are pitching strikes at ATM, they're not coming to bat in their own right. Ethernet is a great way to feed data-driven fiber remotes, a great link between data devices in a metro network, and a great foundation for metro data services. However, the fact that it is not a suitable worldwide data protocol is proved by the fact that IP has swept the Interment and the WAN space. In some cases, the problem is that there are no standards in either the IP or Ethernet area.
