+RFC 3595 Textual Conventions for IPv6 Flow Label September 2003
+
+
+1. Introduction
+
+ Several standards-track MIB modules have defined objects to represent
+ an IPv6 Flow Label (sometimes referred to as Flow ID) [RFC2460]
+ [FLOWLABEL] and IPv6 Flow Label filters. Unfortunately the result is
+ a set of different definitions for the same piece of management
+ information. This may lead to confusion and unnecessary complexity.
+
+ This document defines a set of textual conventions (TCs) that can and
+ should be (re-)used in MIB modules, so that they all represent an
+ IPv6 Flow Label in the same way. In fact, PIB modules can and should
+ also use these TCs when they need to represent an IPv6 Flow label.
+
+2. The Internet-Standard Management Framework
+
+ For a detailed overview of the documents that describe the current
+ Internet-Standard Management Framework, please refer to section 7 of
+ RFC 3410 [RFC3410].
+
+ Managed objects are accessed via a virtual information store, termed
+ the Management Information Base or MIB. MIB objects are generally
+ accessed through the Simple Network Management Protocol (SNMP).
+ Objects in the MIB are defined using the mechanisms defined in the
+ Structure of Management Information (SMI). This memo specifies a MIB
+ module that is compliant to the SMIv2, which is described in STD 58,
+ RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
+ [RFC2580].

+
+4. Security Considerations
+
+ The MIB module contained in this memo does not define any management
+ objects. Instead, it defines a set of textual conventions which may
+ be used by other MIB modules to define management objects.
+
+ Meaningful security considerations can only be written for MIB
+ modules that define concrete management objects. This document has
+ therefore no impact on the security of the Internet.
+
+5. Intellectual Property Statement
+
+ The IETF takes no position regarding the validity or scope of any
+ intellectual property or other rights that might be claimed to
+ pertain to the implementation or use of the technology described in
+ this document or the extent to which any license under such rights
+ might or might not be available; neither does it represent that it
+ has made any effort to identify any such rights. Information on the
+ IETF's procedures with respect to rights in standards-track and
+ standards-related documentation can be found in BCP-11. Copies of
+ claims of rights made available for publication and any assurances of
+ licenses to be made available, or the result of an attempt made to
+ obtain a general license or permission for the use of such
+ proprietary rights by implementors or users of this specification can
+ be obtained from the IETF Secretariat.
+
+ The IETF invites any interested party to bring to its attention any
+ copyrights, patents or patent applications, or other proprietary
+ rights which may cover technology that may be required to practice
+ this standard. Please address the information to the IETF Executive
+ Director.

+7. Acknowledgments
+
+ This document was produced as a result of a review of the use of
+ FlowID in a PIB module and a MIB module. Further investigation found
+ that FlowID and FlowLabel objects were defined in a few other MIB
+ modules. The editor would like to thank all who contributed to the
+ discussion that resulted in this document, particularly Juergen
+ Schoenwaelder for finding and reporting most of the other MIB modules
+ that were using/defining a FlowLabel object. Juergen also suggested
+ the very first direction for a common TC for these objects. Further
+ contributions were received from Fred Baker, Dan Romascanu, Kwok Ho
+ Chan, Margaret Wasserman, Brian Carpenter, Andy Bierman, Randy
+ Presuhn, Branislav Meandzija, Brian Williams, Ravi Sahita. We also
+ received initial input from 3GPP that expressed the requirement to be
+ able to specify a wildcard for FlowID or FlowLabel. Further helpful
+ review comments were received from Brian Carpenter, John Loughney,
+ Pekka Savola.
