Global Virtual Private LAN Service

Six classes of service ensure flexible data management, enabling differentiation between application types and prioritisation of business-critical traffic. In addition, virtual sub networks (virtual LANs) can be created in order to segregate data for different business processes, while Internet access over VPLS helps maximise network investment. Global VPLS can also be interconnected with existing IP VPNs to create a hybrid network or support a phased migration to Ethernet.

An any-to-any service, Telstra’s global VPLS is delivered over a robust infrastructure based on Multi Protocol Label Switching (MPLS) technology. A high degree of fault tolerance is therefore included as standard; should a network failure occur, traffic is automatically redirected via the best available alternative route with minimal service disruption.

Global VPLS offers all the control of Frame Relay and ATM networks, combined with the higher performance of IP VPNs. By operating at OSI layer 2, it allows end-to-end routing to be controlled in-house – ideal for satisfying security or compliance requirements.

Telstra now delivers MEF-compliant Ethernet Network Interface Devices (NIDs) as standard on all customer sites and Ethernet Media Convertors (EMCs) can be used where Ethernet access circuits into the customer premises are not available.
