NOS Panel II: Brownfield Applications in Legacy Networks

Session Description
This summit and panel discussion will seek to explore the opportunites and difficulties for network operators to deploy new leading-edge technologies and innovative newtork architectures to expand their network capacity and functionality, simplify thier network operations, and make thier production platforms and service portfolio more flexible and cost-efficient.

Open network disaggregation across different network domains and OSI layers, including the all important optical fibre transport, combined with an automated control and orchestration archetecture promes to be one of the keys to achieving these goals. 

Disaggregated network elements, such as a new high-capacity "alien" optical transceivers, can be combined with legacy optical line systems from the incumbent carriers' "brownfield" environment. There and in conventional closed-vendor domains, upgrading to new types of high-capacity network elements without replacing parts of the existing transport infrastructure can save carriers enormous costs.

However, such upgrade paths are not without principal hurdles, special adaptations or intergration problems, e.g., distance limitations of new transceivers that have to fit into existing network topologies. The views of network operators with very different prerequisites are discussed.
