Protocols to support advanced content delivery capability in next generation service overlay networks including 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 are specified in this standard. Content discovery, content cache and storage management, content delivery control, and transport QoS control, including contextaware and dynamically adaptive content delivery operations, are supported by the content delivery capability.

An abstraction layer for multiple home networking technologies that provides a common interface to widely deployed home networking technologies is defined in this standard: IEEE 1901 over power lines, IEEE 802.11 for wireless, Ethernet over twisted pair cable, and MoCA 1.1 over coax. Connectivity selection for transmission of packets arriving from any interface or application is supported by the 1905.1 abstraction layer. Modification to the underlying home networking technologies is not required by the 1905.1 layer, and hence it does not change the behavior or implementation of existing home networking technologies. Introduced by the 1905.1 specification is a layer between layers 2 and 3 that abstracts the individual details of each interface, aggregates available bandwidth, and facilitates seamless integration. The 1905.1 also facilitates end-to-end quality of service (QoS) while simplifying the introduction of new devices to the network, establishing secure connections, extending network coverage, and facilitating advanced network management features including discovery, path selection, autoconfiguration, and quality of service (QoS) negotiation.

A common framework for sensor performance specification terminology, units, conditions, and limits is provided. Specifically, the accelerometer, magnetometer, gyrometer/ gyroscope, accelerometer/magnetometer/gyroscope combination sensors, barometer/pressure sensors, hygrometer/humidity sensors, temperature sensors, light sensors (ambient and RGB), and proximity sensors are discussed.

The physical layer (PHY) and medium access control (MAC) sublayer specifications for low-data-rate wireless connectivity with fixed, portable, and moving devices with no battery or very limited battery consumption requirements are defined in this standard. In addition, the standard provides modes that allow for precision ranging. PHYs are defined for devices operating in a variety of geographic regions.

This standard specifies the air interface, including the medium access control layer (MAC) and physical layer (PHY), of combined fixed and mobile point-to-multipoint broadband wireless access (BWA) systems providing multiple services. The MAC is structured to support the WirelessMAN-SC, WirelessMAN-OFDM, and WirelessMAN-OFDMA PHY specifications, each suited to a particular operational environment. The standard enables rapid worldwide deployment of innovative, cost-effective, and interoperable multi-vendor broadband wireless access products, facilitates competition in broadband access by providing alternatives to wireline broadband access, encourages consistent worldwide spectrum allocation, and accelerates the commercialization of broadband wireless access systems.

An extensible IEEE 802(R) media access independent services framework (i.e., function and protocol) is defined that enables the optimization of services including handover and other services when performed between heterogeneous IEEE 802 networks. These services are facilitated by this standard when networking between IEEE 802 networks and cellular networks.

Ethernet local area network operation is specified for selected speeds of operation from 1 Mb/s to 400 Gb/s using a common media access control (MAC) specification and management information base (MIB). The Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC protocol specifies shared medium (half duplex) operation, as well as full duplex operation. Speed specific Media Independent Interfaces (MIIs) allow use of selected Physical Layer devices (PHY) for operation over coaxial, twisted pair or fiber optic cables, or electrical backplanes. System considerations for multisegment shared access networks describe the use of Repeaters that are defined for operational speeds up to 1000 Mb/s. Local Area Network (LAN) operation is supported at all speeds. Other specified capabilities include: various PHY types for access networks, PHYs suitable for metropolitan area network applications, and the provision of power over selected twisted pair PHY types.(The PDF of this standard is available at no cost to you compliments of the IEEE GET program https://ieeexplore.ieee.org/browse/standards/get-program/page)

This standard defines the syntax and semantics of a format used to express power intent in energy aware electronic system design. Power intent includes the concepts and information required for specification and validation, implementation and verification, and modelling and analysis of power managed electronic systems. This standard also defines the relationship between the power intent captured in this format and design intent captured via other formats (e.g., standard hardware description languages and cell libraries).

This standard defines topology, functions, and governance for cloud-to-cloud interoperability and federation. Topological elements include clouds, roots, exchanges (which mediate governance between clouds), and gateways (which mediate data exchange between clouds). Functional elements include name spaces, presence, messaging, resource ontologies (including standardized units of measurement), and trust infrastructure. Governance elements include registration, geo-independence, trust anchor, and potentially compliance and audit. The standard does not address intra-cloud (within cloud) operation, as this is cloud implementation-specific, nor does it address proprietary hybrid-cloud implementations.

This document specifies a generic knowledge management framework for a smart city, focusing on creating, capturing, sharing, using and managing smart city knowledge. It also gives the key practices which are required to be implemented to safeguard the use of knowledge, such as interoperability of heterogeneous data and governance of multi-sources services within a smart city.

ISO 12006-3:2007 specifies a language-independent information model which can be used for the development of dictionaries used to store or provide information about construction works. It enables classification systems, information models, object models and process models to be referenced from within a common framework.

This guide provides the technical background, rationale and guidance to support the application of the substantially revised IEEE 1547, Standard for Interconnection and interoperability of Distributed Energy Resources (DER) with Electric Power Systems (EPS) and Associated Interfaces. The document will describe how the requirements and default settings specified in 1547 have been carefully chosen to balance distribution and bulk system needs for increasing penetration of DER. It further expands IEEE 1547 by addressing certain DER integration issues that are not fully addressed by the base standard, e.g. reclosing coordination and limitation of over-voltage in the Area EPS. The guide will address (1) the concept of the newly-introduced performance categories and their assignment to specific DER by an Authority Governing Interconnection Requirements (AGIR); (2) the new requirements for voltage and reactive power control, frequency control, response to abnormal conditions including ride-through; (3) the flexibility provided by the newly-introduced ranges of adjustability for control settings as well as for voltage and frequency trip settings to fully exploit the revised IEEE 1547's potential and to account for specific system characteristics; (4) the interoperability and communication interface requirements; and (5) the test and verification practices, including design and as-built installation evaluations for utility-scale DER, that have not been included in the previous version of the standard. Presented in the document are technical descriptions and schematics, applications guidance and interconnection examples to enhance the use of IEEE 1547.
