Emerging new applications for a mature technology. Frame relay has recently emerged as a popular interface choice for today's high-speed services, including videoconferencing, SNA networking, voice-over data, and high-speed Internet access itself. Stressing services rather than bits and bytes, this book reexamines this mature technology in light of these new applications. It contrasts frame relay with alternative technologies, demonstrates how to use it to tackle real business problems, and explains how frame-enabled systems can be exploited for cost-effective solutions.
