3. Terms, definitions, and notation
For the purposes of this document, the following terms and definitions apply. The IEEE StandardsDictionary: Glossary of Terms & Definitions should be consulted for terms not defined in this clause.
3.1 Conformance levels
Several keywords are used to differentiate between different levels of requirements and optionally, asfollows:
may: Indicates a course of action permissible within the limits of the standard with no implied preference(“may”means“is permitted to”).
shall: Indicates mandatory requirements strictly to be followed in order to conform to the standard andfrom which no deviation is permitted (“shall means “is required to”).
should: An indication that among several possibilities, one is recommended as particularly suitablewithout mentioning or excluding others: or that a certain course of action is preferred but not necessarilyrequired; or that (in the negative form) a certain course of action is deprecated but not prohibited (“should’means “is recommended to”).
3.2 Definitions
Audio/Video Transport Protocol (AVTP): The protocol defined by IEEE Std 1722-2011. As anadjective, it indicates that the modified noun is specified in or interpreted in the context of this standard.
audio/video bridging (AVB) bridge: A bridge that implements IEEE Std 802.10-2005 as amended bythe Stream Reservation Protocol (SRP), Forwarding and Oueuing Enhancements for Time SensitiveStreams (FOTSS), and implements the generalized Precision Time Protocol (gPTP).
Audio/Video Transport Protocol (AVTP) stream: An AVTP stream is between one Talker and one ormore Listeners.
Audio/Video Transport Protocol (AVTP) gateway: A device that transports AVTP audio/video streamsbetween an audio/video bridging (AVB) network and another type of media, for example, anIEEE 1394 bus.
doublet: Two octets of data
frame: A frame is a complete unit of data transmission as transmitted on the network, including mediaaccess control(MAC) layer addressing and cyclic redundancy check (CRC).
