Current networking demands of international networks, voice alternatives, virtual private networks, and network quality of service have generated renewed interest in frame relay. The traditional frame relay roles in SNA and LAN router connectivity remain undiminished, but frame relay has proven remarkably well-suited for a number of high speed networking situations. However, books on frame relay have been mainly restricted to exploring ITU-T plans for an ISDN-based frame relay infrastructure that has never appeared. This is the first volume to detail how real-world Frame Relay Forum networks are currently implemented. Walter Goralski’s lucid style makes complex discussions on frame relay for voice, IP, ATM, and other uses easy to understand for the novice or expert.
