There have been a number of papers presented that depict deploying Ethernet Services and the Operational Expenditure benefits of Ethernet services. All talk about the ubiquity of Ethernet and the reduced cost of deployment without looking at a true network turn up procedure with a customer and trouble shooting pactices to achieve the anticipated packet throughput. None have looked at specific pitfalls across the spectrum of turn up issues.Looking Glass Networks, Inc. is a Carriers Carrier service provider in the 12 major Metropolitan areas of the United States. We currently offer a combination of lit TDM, Ethernet and Wavelength services as well as dark fiber and collocation services to other service provider and enterprise customers. LGN has done extensive cost analysis and time study on the subject of implementing and turning up an Ethernet service for both layer 1 point to point services as well as layer 2 network services.We intend to show a baseline topology architecture and equipment cost for an Ethernet over SONET implementation for a layer 1 Ethernet service. The additional capex and opex costs beyond the network hardware: test equipment, operations and maintenance, OSS management and software licensing will be documented in comparison to a SONET TDM service implementation. LGN will show a test implementation diagram for a layer 1 based Ethernet service and an implementation diagram for a layer 2 based Ethernet test implementation. We will demonstrate quantitative and qualitative analysis on turn up time and trouble shooting/implementation requirements for the Ethernet services versus a SONET TDM service. We will review Customer acceptance criteria for each service type and which one is best for a specific set of circumstances and number of service sites.We will then present some specific case studies that illustrate the pitfalls of the service turn up and educating the customer on service expectation.
