1903-2011 - IEEE Standard for the Functional Architecture of Next Generation Service Overlay Networks
A framework of Internet Protocol (IP)-based service overlay networks is described and context-aware [e.g., such as required Quality of Service (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, are specified in this Next Generation Service Overlay Network (NGSON) standard. The NGSON architecture provides advanced service- and transport-related functions to support context-aware, dynamically adaptive, and self-organizing networks. This standard specifies a functional architecture 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 delivery among FEs and external components. NGSON may operate with different underlying networks such as IP Multimedia Subsystem (IMS), next generation network (NGN), peer-to-peer (P2P) overlay, or Web to transmit NGSON signaling messages and/or media among its users and services. Specifications of underlying networks are outside scope of this standard.
1903.2-2017 - IEEE Standard for Service Composition Protocols of Next Generation Service Overlay Network
This standard specifies protocols among Service Composition (SC) Functional Entity (FE), Service Discovery and Negotiation (SDN) FE, Context Information Management (CIM) FE, Service Routing (SR) FE and Service Policy Decision (SPD) FE to support service composition capabilities in next generation service overlay network. The capabilities of service composition aim to support service chaining and instantiation, specification interpretation, service brokering and execution, and context-aware and dynamically adaptive service composition.
1903.3-2017 - IEEE Standard for Self-Organizing Management Protocols of Next Generation Service Overlay Network
This standard specifies protocols between Overlay Management (OM) Functional Entity (FE) and all other NGSON FEs, and/or NGSON nodes to enable OM FE involved self-organizing management capability. This capability includes activation and deactivation of an NGSON node and addition, deletion, movement and copy of an NGSON function entity from or to an NGSON node. This standard also specifies protocols among Service Routing (SR) FEs to enable OM FE non-involved self-organizing management capability such as re-organization of overlay structure among multiple SR FEs for recovery from a failed or overloaded SR FE or for performance improvement of service routing.
