This Next Generation Service Overlay Network (NGSON) standard describes a framework of Internet Protocol (IP)-based service overlay networks and specifies context-aware [e.g., such as required quality ofservice (QoS) level; type of service such as real time versus data; nature of data stream such as I-frame versus B-frame; and type of terminal such as TV monitor versus personal digital assistant], dynamically adaptive (e.g., using locally derived information to discover, organize, and maintain traffic flows in the network within a local area network), and self-organizing networking capabilities (e.g., developing network structures based on the needs of the customers and the capabilities of existing network structures), including advanced routing and forwarding schemes, that are independent of underlying networks.The NGSON architecture provides advanced service and transport-related functions to support contextaware, dynamically adaptive, and self-organizing networks. This standard specifies a functionalarchitecture for NGSON. The functional architecture consists of a set of functional entities (FEs), their functions, reference points, and information flows to illustrate service interaction and media deliveryamong FEs and external components.NGSON may operate with different u
