                        xDSL Multi-Pair Bonding
       Using Time-Division Inverse Multiplexing (G.Bond/TDIM) MIB

Abstract

   This document defines a Management Information Base (MIB) module for
   use with network management protocols in TCP/IP-based internets.
   This document proposes an extension to the GBOND-MIB module with a
   set of objects for managing multi-pair bonded xDSL interfaces using
   Time-Division Inverse Multiplexing (TDIM), as defined in ITU-T
   Recommendation G.998.3.

1.  Introduction

   Multi-pair bonding using Time-Division Inverse Multiplexing (TDIM),
   a.k.a. G.Bond/TDIM, is specified in ITU-T Recommendation G.998.3
   [G.998.3], which defines a method for bonding (or aggregating)
   multiple xDSL lines (or individual bearer channels in multiple xDSL
   lines) into a single bidirectional logical link carrying a mix of
   various traffic streams, e.g., Ethernet, Asynchronous Transfer Mode
   (ATM), Time-Division Multiplexing (TDM).

   The MIB module defined in this document provides G.Bond/TDIM-specific
   objects for the management of G.998.3 bonded interfaces, extending
   the common bonding objects specified in the GBOND-MIB [RFC6765]
   module.

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
