A tree structure in an SDN such as an access network is identified. Control plan management is provided using the tree structure. A controller configures changes in the SDN and provides notifications to other controllers after configuring devices under its control. A controller prioritizes the status of downstream and/or upstream devices based on a type or direction of data flow when making configuration decisions. A controller provides notifications to other controllers by prioritizing notifications based on the hierarchical position of devices."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Controller communications in access networks","description":"Control plane management based on the physical topology of nodes in software-defined networks (SDNs) is provided.
