In transforming their optical transport networks, operators must consider multiple choices to determine the appropriate approaches in terms of the network design and optimization with newly available technologies, the network transition and evolution strategy and maximize at the same time the return on their investment. For instance, they need to take into account the network architecture such as...
With the explosive growth in data traffic, operators are faced with the challenges of transforming their existing networks through careful investment in the right technology to lower the cost per bit. In this paper, we explored the economic impact of NG-OTN technologies on future converged IP Optical transport network through a comprehensive case study of a typical service provider in Asia Pacific...
In planning the evolution and transformation of optical transport networks, operators are faced with multiple difficult choices in terms of the network design and optimization with emerging technologies and transition strategy to achieve higher flexibility, scalability and resiliency at minimum expenditures. We attempt to answer these critical questions by means of a practical methodology. We demonstrate...
In planning and designing a large optical transport network, operators are faced with a complex optimization problem that needs to take into account the mix of legacy and new services, new technologies and network transition constraints, while satisfying high network flexibility and scalability. In this paper, we approach the answers to these difficult questions through a pragmatic methodology. We...
