EBU – Tech 3345 End-to-End IP Network Measurement for Broadcast Applications Parameters & Management Information Base (MIB) Geneva July 2011 1 Conformance Notation This document contains both normative text and informative text. All text is normative except for that in the Introduction, any section explicitly labelled as ‘Informative’ or individual paragraphs which start with ‘Note:’. Normative text describes indispensable or mandatory elements. It contains the conformance keywords ‘shall’, ‘should’ or ‘may’, defined as follows: ‘Shall’ and ‘shall not’: Indicate requirements to be followed strictly and from which no deviation is permitted in order to conform to the document. ‘Should’ and ‘should not’: Indicate that, among several possibilities, one is recommended as particularly suitable, without mentioning or excluding others. OR indicate that a certain course of action is preferred but not necessarily required. OR indicate that (in the negative form) a certain possibility or course of action is deprecated but not prohibited. ‘May’ and ‘need not’: Indicate a course of action permissible within the limits of the document. Default identifies mandatory (in phrases containing “shall”) or recommended (in phrases containing “should”) presets that can, optionally, be overwritten by user action or supplemented with other options in advanced applications. Mandatory defaults must be supported. The support of recommended defaults is preferred, but not necessarily required. Informative text is potentially helpful to the user, but it is not indispensable and it does not affect the normative text. Informative text does not contain any conformance keywords. A conformant implementation is one which includes all mandatory provisions (‘shall’) and, if implemented, all recommended provisions (‘should’) as described. A conformant implementation need not implement optional provisions (‘may’) and need not implement them as described.
