Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
In exceptional circumstances, when the joint technical committee has collected data of a different kind from
that which is normally published as an International Standard (“state of the art”, for example), it may decide to
publish a Technical Report. A Technical Report is entirely informative in nature and shall be subject to review
every five years in the same manner as an International Standard.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC TR 29181-6 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 6, Telecommunications and information exchange between systems.
ISO/IEC TR 29181 consists of the following parts, under the general title Information technology — Future
Network — Problem statement and requirements:
 Part 1: Overall aspects
 Part 3: Switching and routing
 Part 4: Mobility
 Part 6: Media transport
 Part 7: Service composition
The following parts are under preparation:

Introduction
ISO/IEC TR 29181-1 describes the definition, general concept, problems and requirements for the Future
Network (FN). The other parts of ISO/IEC TR 29181 provide details of various components of the technology.
This part of ISO/IEC TR 29181 identifies problem of the media transport in the IP-based networks and
examines the requirements for the transport of media data over the Future Network.

statement and requirements —
Part 6:
Media transport
1 Scope
This part of ISO/IEC TR 29181 describes the problem statement and requirements for the Future Network in
the perspective of Media Transport. This part of ISO/IEC TR 29181 specifies:
a) detailed description of the media transport requirements in the Future Network;
b) identification and definition of services, basic and media services, which will fit the requirements for
communications over heterogeneous environments supporting various user preferences, for any kind of
media content, either time-dependent or time-independent;
c) requirements and functionalities of Media Aware Network Elements, which are intended to be nodes in
the network to provide seamless media experiences to users.

Part 1: Overall aspects
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO/IEC TR 29181-1 and the following
apply.
3.1
data
sequence of octets which is conveyed across the network as a single unit
[SOURCE: ISO/IEC TR 29181-3, 3.1]
3.2
media
sequence of bits in a defined format which encodes physical entities such as images, sounds, and text.
3.3
time-independent media
media where the semantic of the content does not depend upon a presentation according to the time domain

EXAMPLE 1 text
EXAMPLE 2 still image
3.4
time-dependent media
media where there exists a temporal relation amongst the media units
EXAMPLE 1 audio
EXAMPLE 2 video
3.5
content
media media that is carried in the payload of datagrams sent over the network
3.6
static content
time-independent media that is carried in the payload of datagrams sent over the network
3.7
streamed content
time-dependent media that is carried in the payload of datagrams sent over the network but does not have
requirements for latency
EXAMPLE 1 MP3 files
EXAMPLE 2 Video-on-Demand
3.8
live content
time-dependent media that is carried in the payload of datagrams sent over the network and has requirements
for latency.
EXAMPLE 1 telephone conversation
EXAMPLE 2 video conference
3.9
encapsulation
additional octets or other symbols associated with a data unit which serve to delimit it or to identify aspects of
the service it should receive
[SOURCE: ISO/IEC TR 29181-3, 2.15]
3.10
container
encapsulation structure containing a payload, either data units or content, and the header composed by two
parts, what refers to the payload and to the underlying network
NOTE Container has attributes as header fields, which some are related to particular services, and others are
general and specific for a sort of communication.
3.11
context
set of data or information that completely describes a particular communication environment at a particular
point in time
[SOURCE: ISO 16484-5:2007 (Identifier: CDB-00119069-001)]

3.12
context-awareness
ability of a network to be aware of the context and react accordingly in order to adapt either itself or the data
conveyed over
3.13
modular paradigm
paradigm where complex functions are composed by well-known and deterministic basic functions
NOTE In network realm, protocols are breaking down into its fundamental (also called atomic) functions, such as
sequencing, cyclic redundant coding, addressing, and so on, which combined results into complex functions (or protocols).
3.14
MANE (Media Aware Network Element)
content and context aware network element capable of processing media content passing through to
accommodate a given content or service according to the context
