1.1 Glossary

  • Article

This document uses the following terms:

802.1p: A 3-bit field within the IEEE 802.1Q frame format (see [IEEE802.1Q]) that can be used to specify user priority on IEEE 802.1D networks.

available bandwidth: A term used to describe the maximum throughput that a flow between two hosts can achieve in the presence of cross-traffic.

bottleneck bandwidth: A term used to describe the maximum throughput that a flow between two hosts can achieve in the absence of cross-traffic.

Digital Living Network Alliance (DLNA): A cross-industry organization of leading consumer electronics, computing industry, and mobile device companies, which are focused on delivering interoperability guidelines to allow entertainment devices in the home to operate with each other. DLNA has embraced WMM for its QoS strategy.

initiator: A device that initiates a qWave-WD or qWave session.

ISO/OSI reference model: The International Organization for Standardization Open Systems Interconnection (ISO/OSI) reference model is a layered architecture (plan) that standardizes levels of service and types of interaction for computers that are exchanging information through a communications network. Also called the OSI reference model.

network byte order: The order in which the bytes of a multiple-byte number are transmitted on a network, most significant byte first (in big-endian storage). This may or may not match the order in which numbers are normally stored in memory for a particular processor.

network socket: An endpoint of a bidirectional process-to-process communication flow across an IP based network, such as the Internet. A socket is an interface between an application process or thread and the TCP/IP protocol stack provided by the operating system.

one-way delay (OWD): One-way delay is the measure of time it takes for a network packet to reach its destination.

Quality of Service (QoS): A set of technologies that do network traffic manipulation, such as packet marking and reshaping.

sink: A device that is the target of a qWave-WDsession.

TCP data stream: A logically contiguous data buffer provided by an application to TCP.

Wi-Fi Multimedia (WMM®): WMM enables Wi-Fi access points to prioritize traffic and optimizes the way shared network resources are allocated among different applications. For more details, see [WF-WMM1.2].

MAY, SHOULD, MUST, SHOULD NOT, MUST NOT: These terms (in all caps) are used as defined in [RFC2119]. All statements of optional behavior use either MAY, SHOULD, or SHOULD NOT.
