Tellabs enhances the Tellabs 6300 managed transport series with layer 2 switching to enable telecom operators to deliver profitable data services with MPLS-managed QoS

Fiber Optics Weekly Update, May 30, 2003

Tellabs announced the second phase of its data migration strategy, adding Layer 2 switching and guaranteed Quality-of-Service (QoS) to its next-generation SDH portfolio. Available this quarter, the new and enhanced Tellabs 6300 managed transport series enables operators to support advanced Ethernet Private Networks, providing differentiated carrier-class data services to their business customers. The Tellabs 6300 Ethernet solution uses MPLS to provide a guaranteed QoS not available with standard Ethernet equipment. Instead of relying on simple Ethernet prioritization mechanisms, the Tellabs 6300 series manages and delivers the committed bandwidth within a multipoint network for each data flow. The Layer 2 switching functionality enables network operators to build large Ethernet networks over long distances, maintaining the flexibility and scalability of smaller data networks. Operators can offer highly flexible and differentiated services such as Ethernet VPNs or Ethernet Private Lines for applications includ ing Internet access, business intranets, voice over IP and video.

The use of MPLS enables managed over-subscription and allows operators to offer flexible, bandwidth-based Service Level Agreements (SLAs) to end customers whilst offering superior scalability, security and customer segregation compared with Virtual Local Area Networks-based mechanisms (VLAN). It also provides better utilization of the network bandwidth than, for example, TDM leased lines. With the transport network now contributing to the Layer 2 switching, the number of physical interfaces between the transport network and its data clients is considerably reduced, lowering the overall network costs.

Using LCAS in the Tellabs 6300 series, operators can resize the capacity of links in the transport network at any time without interrupting traffic, thereby allowing them to scale Ethernet service bandwidth instantly as required. Further, LCAS offers resiliency against network failure, and can enable network efficiency to be doubled by utilizing the redundant bandwidth reserved by traditional SDH protection.

The Tellabs 6300 solution is a breakthrough next-generation SDH platform that enables network operators to deliver data efficiently and profitably through their existing transport platform. The solution offers integrated management of data, SDH and DWDM networks from a single network management system, enabling point-and-click network operations across network elements from the edge to the core. These leading-edge, high-density products cost- effectively collect and consolidate voice and data traffic in the metro and regional areas and are already deployed throughout Asia-Pacific, Europe, the Middle East, Africa and Latin America.
