|Next-Generation Service Overlay Network (NGSON) Working Group|
On 10 September 2011, the IEEE-SA Standards Board approved IEEE Std 1903-2011, IEEE Standard for the Functional Architecture of Next-Generation Service Overlay Networks. The document is available for sale through techstreet.com.
The project authorization requests (PARs) for P1903.1, P1903.2, and P1903.3 were approved by the IEEE-SA Standards Board on 7 December 2011. The PARs were approved for modification from entity- to individual-based projects on
5 December 2012.
The project scopes are as follows:
P1903.1: This Standard specifies protocols among Content Delivery (CD) Functional Entity (FE), Service Routing (SR) FE, Service Policy Decision (SPD) FE, Service Discovery and Negotiation (SDN) FE, and Context Information Management (CIM) FE to support advanced content delivery capability in next generation service overlay networks.
The content delivery capability aims to support content discovery, content cache and storage management, content delivery control, and transport Quality of Service (QoS) control including context-aware and dynamically adaptive content delivery operations.
P1903.2: 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 contextaware and dynamically adaptive service composition.
P1903.3: 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 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.
These projects are sponsored by the IEEE Communications Society/Standards Development Board (COM/SDB).
