ATM-based WANs are therefore one of the most efficient yet costly approaches for ensuring a high degree of responsiveness to global teams working collaboratively on complex, involved projects.

The majority of global teams however rely on Frame Relay WANs that average 45 Mbps and cost significantly less than ATM networks. Frame Relay WANs support both switchable and fixed configuration, are scalable to support bursts in audio and digital traffic and also have global wide availability. As more projects become more global in scope, Frame Relay as a WAN technology option is increasingly being chosen in mid-size and small companies. Smaller businesses that have global partnerships are using new techniques to optimize their Frame Relay networks to gain the cost advantages and lower total cost of ownership that is possible using VoIP and data interchange standards (Awan, Shih, Durresi, 2008).
