Optical access networks today are typically deployed as single path, single channel connections from the metro domain towards the end users. This architecture, however, will not be appropriate for accommodating business critical services, and particularly x-haul services in wireless and copper networks. Redundant, flexible and manageable access links will increasingly be required. Likewise, network designs will be needed allowing for reliably handling different kinds of traffic patterns with varying needs for capacity and latency, such as sustained capacity per node, sporadic traffic or aggregate peak rates even exceeding the capacity that the network was designed for.

The panel shall identify shortcomings of current access network architectures and provide proposals how to improve their resilience both on the physical and MAC layer as well as on the traffic engineering level. Which operational benefits can be gained from monitoring means and SDN-type of resource management? How can increased requirements on network management and maintenance be met also in access? What is the acceptable ratio of equipment and software efforts vs. improved quality and availability of services?
