Abstract:

Bandwidth on demand services, meshed restoration and optical virtual private networks are widely discussed today in an isolated manner. The target of this presentation is to bring the concepts together and to show the mutual benefit of combining them. The benefits of restoration in meshed compared to ring based transmission networks are widely accepted and recognized. But this presentation goes a step further and analyzes the benefits of a collaboration between an IP/MPLS control plane and intelligent optical networks. The underlying principle is based optical VPNs and provides substantial overall cost savings compared to unrelated networking mechanisms. By combining O-VPNs with service aware survivability up to 37% CAPEX savings were found in a real network compared to a traditional approach.

Gert Grammel was awarded a Master degree in Cybernetics at the University of Stuttgart. He joined Alcatel in 1994 as Systems Engineer for network management of line transmission systems. In 1996, he joined the team of Cable TV Networks as Senior Systems Engineer for cable telephony solutions. In 1999, he moved to the Network Strategy Group in the Terrestrial Networks Division (now Optical Networks Division), where he worked on multi service networks and on the standardization of GMPLS and ASON.

Currently he is in charge of investigating the strategy and evolution of transport networks. This involves designing network architectures and transport networks using the latest management, control and transmission technology to meet the projected growth in demand, faster lead times and improved quality service.
