Tellabs Adds L2 Switching

LONDON -- Tellabs today announced the second phase of its data migration strategy, adding Layer 2 switching and guaranteed Quality-of-Service (QoS) to its next-generation Synchronous Digital Hierarchy (SDH) portfolio. Available this quarter, the new and enhanced Tellabs 6300 managed transport series enables operators to support advanced Ethernet pivate Networks, providing differentiated carrier-class data services to their business customers.

"The integration of Multi-Protocol Label Switching (MPLS) takes SDH into a very strong evolution path for the optical network," commented Mark Lum, Director of RHK's Optical Networks: Europe program. "This approach merits the most serious business consideration from multi-service providers and network operators." RHK believes that Tellabs is the first vendor to deliver MPLS-managed Layer 2 Virtual Private Networks (VPN) services on a single SDH platform that also features Generic Framing Procedure (GFP), Virtual Concatenation (VCX) and Link Capacity Adjustment Scheme (LCAS) resiliency.

The Tellabs 6300 Ethernet solution uses MPLS to provide a guaranteed QoS not available with standard Ethernet equipment. Instead of relying on simple Ethernet prioritisation mechanisms, the Tellabs 6300 series manages and delivers the committed bandwidth within a multipoint network for each data flow.

"With the addition of Layer 2 switching to our Tellabs 6300 managed transport series, Tellabs becomes the first vendor to deliver Ethernet-over-SDH solutions combining GFP mapping, LCAS resiliency and MPLS-based end-to-end QoS on a single platform," says Peter Viereck, vice president and general manager optical transport networks at Tellabs. "Operators can currently start the evolution of the equipment that will enable them to support new profitable Ethernet services with greater operational expenditure and capital expenditure savings."
