ATM and Frame Relay users plan move to IP VPN

Most network managers who use Asychronous Transfer Mode (ATM) and Frame Relay services plan to migrate to IPvirtual private networks (VPNs) or carrier Ethernet services within the next two years, a study has revealed.

Most network managers who use Asychronous Transfer Mode (ATM) and Frame Relay services plan to migrate to IPvirtual private networks (VPNs) or carrier Ethernet services within the next two years, a study has revealed.

A survey of 78 network managers by research firm Current Analysis suggested the trend was being driven by the need for more bandwidth and the convergence of voice, video and data services.

IP VPNs are the preferred alternative for 75% of those planning to migrate from Frame Relay services, although 61% of ATM users plan to implement Ethernet as well.

"Given that this increased reliance on networks will rise, enterprises are continuously evaluating wide area network services as a means of ensuring support for business operations," said David Hold, senior analyst for network services at Current Analysis.

Legacy Wan services such as ATM and Frame Relay are common in enterprises, but for many the transition to next-generation IP/Multi-Protocol Label Switching (MPLS) and carrier Ethernet services is imminent.

Virtual private local area network services (VPLS) can provide Ethernet-based communication over IP/MPLS networks, but the survey revealed that they were not widely used, and network managers did not know much about them.

Most respondents had no plans to deploy VPLS, and 40% did not know whether their carrier offered the service. However, of those users that had evaluated VPLS, 48% preferred it to ATM and Frame Relay.
