For many years optical transport networks have been deployed using TDM technologies such as PDH, SONET and OTN providing highly performant and resilient services to voice and data networks. With recent advances in router/switch architectures, embedded control plane protocols and central application software a single MPLS network layer can deliver any service that so far only PDH, SONET or OTN could deliver. During this session we will talk about some common “concerns” such as cost of transmission, latency & jitter, bandwidth guarantees & loss, service assurance & OAM and how they are no longer valid for a “neatly designed” MPLS transport network allowing network operators to remove the complexity of running many parallel networks. Submitted for Christian Schmutzer, Principal Engineer, Optical Systems, Cisco Bio: Christian Schmutzer is a Principal Engineer at Cisco Systems and has been with the company since 1998. Early on Schmutzer worked primarily on the design and deployment of large service provider backbones – with the focus on optical and routing technologies. Schmutzer then drove, as the technical expert, the product development and marketing strategy for the ASR 9000 and Cisco 7600 series router platforms. Since 2013 Schmutzer has been working on Packet/Optical network architectures and product development. He is the Principal Architect for Cisco’s Transport Network Modernization Architecture. As a speaker for technical tutorials worldwide, he frequently shares his practical experience. He received his Masters from the Fachhochschule Technikum-Wien, Austria
