Internet-Draft G.Bond/TDIM MIB August 2009
1. Introduction
The Multi-pair bonding using time-division inverse multiplexing
(TDIM), a.k.a. G.Bond/TDIM, is specified in ITU-T G.998.3
recommendation [G.998.3], which defines a method for bonding (or
aggregating) of multiple xDSL lines into a single bi-directional
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 GBOND-
MIB [I-D.ietf-adslmib-gbond-mib] 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
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].
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
3. The Broadband Forum Management Framework for xDSL Bonding
This document makes use of the Broadband Forum technical report
Management Framework for xDSL Bonding [TR-159], defining a management
model and a hierarchy of management objects for the bonded xDSL
interfaces.
4. Relationship to other MIB modules
This section outlines the relationship of the MIB modules defined in
this document with other MIB modules described in the relevant RFCs.
Specifically, the following MIB modules are discussed: Interfaces
Group MIB (IF-MIB) and G.Bond MIB (GBOND-MIB).
Beili Expires February 18, 2010 [Page 3]
Internet-Draft G.Bond/TDIM MIB August 2009
4.1. Relationship to Interfaces Group MIB module
A G.Bond/TDIM port is a private case of a Bonded multi-pair xDSL
interface and as such is managed using generic interface management
objects defined in the IF-MIB [RFC2863]. In particular an interface
index (ifIndex) is used to index instances of G.Bond/TDIM ports in a
system.
4.2. Relationship to G.Bond MIB module
GBOND-MIB [I-D.ietf-adslmib-gbond-mib] module defines management
objects common for all Bonded multi-pair xDSL interfaces. In
particular is describes the bonding management, port and channel
configuration, initialization sequence etc.
Both GBOND-MIB and GBOND-TDIM-MIB modules are REQUIRED to manage a
G.Bond/TDIM port.
5. MIB Structure
5.1. Overview
All management objects defined in the GBOND-TDIM-MIB module are
contained in a single group gBondTdimPort. This group is further
split into 6 sub-groups:
o gBondTdimPortNotifications - containing notifications (TDIM
Service Down/Up).
o gBondTdimPortConfTable - containing objects for configuration of a
G.Bond/TDIM port.
o gBondTdimPortCapabilityTable - containing objects reflecting
capability of a G.Bond/TDIM port.
o gBondTdimPortStatusTable - containing objects providing overall
status information of a G.Bond/TDIM port, complementing the
generic status information from the ifTable of IF-MIB and
gBondFltStatus of GBOND-MIB.
o gBondTdimServiceTable - containing objects for configuration and
status of the services in a G.Bond/TDIM port.
o gBondTdimPM - containing objects for an OPTIONAL Historical
Performance Monitoring (PM) of a G.Bond/TDIM port.
Beili Expires February 18, 2010 [Page 4]
Internet-Draft G.Bond/TDIM MIB August 2009
5.1.1. TODO/Open Issues
o _EdNote: Should we add Threshold Crossing Alerts for the
Performance Monitoring?_
o _EdNote: We probably don't need 64-bit counters for PM_
o _EdNote: Masking/Inhibition rules for Service Notifications_
5.2. Protection Configuration
G.Bond/TDIM specification allows an optional Forward Error Correction
(FEC) and Interleaver block, which, if supported and enabled,
provides a degree of protection against micro-interruptions, alien
noise, and even individual Bonding Channel Entity (BCE) failures,
a.k.a. cut-line protection.
Management objects in the gBondTdimPortConfTable can be used to
configure and quiery the FEC and Interleaver function of the G.Bond/
TDIM port.
5.3. Service Configuration
Unlike the other two xDSL Multi-Pair Bonding schemes (G.Bond/ATM and
G.Bond/Ethernet), which send the information required for reassembly
of the fragmented data along with the data, G.Bond/TDIM is a
synchronous scheme, requiring both ends to know the data distribution
tables before any actual data transfer can happen.
Management objects in the gBondTdimServiceTable can be used to
configure and quiery the configuration of services transported via
the G.Bond/TDIM link. The services may be configured when the link
is down prior to the link's initialization. The sum of all the
services' bandwidth SHOULD be less or equal to the target data rate
of the bonded link. Note that G.Bond/TDIM links are symmetrical,
i.e. their upstream data rate equals to the downstream data rate.
5.3.1. Management of TDM Services
G.Bond/TDIM protocol provides an ability to map TDM services into the
TDIM bonded link directly, without any additional overhead. It
addresses only structure-agnostic TDM transport, disregarding any
structure that may be imposed on these streams, in particular the
structure imposed by the standard TDM framing [G.704].
There can be up to 60 services defined on a G.Bond/TDIM port.
Services (rows in the gBondTdimServiceTable, indexed by
gBondTdimServiceIdx ) are defined sequentially, starting from index
Beili Expires February 18, 2010 [Page 5]
Internet-Draft G.Bond/TDIM MIB August 2009
1. Rows for the undefined services MUST NOT exist.
During bandwidth degradation services with a lower priority are
impaired or dropped first. Synchronous services (fractional DS1/E1,
clear channel E1/T1, T3/E3, clock) have higher priority than
asynchronous services (Ethernet, ATM, GFP encapsulated). Within the
services of the same type, those with lower index have higher
priority.
The service table, defining the type and size of each service, can
only be changed on a BTU-C side (independently from the port's
operational state), since the GBS-C port communicates the service
table to the peer GBS-R port.
_EdNote: Think about common things between G.Bond/TDIM and PWE3, may
be there's a potential for reuse, see PW-*-MIB modules in
http://www.ietf.org/html.charters/pwe3-charter.html _
5.4. Performance Monitoring
The OPTIONAL performance monitoring counters, thresholds and history
buckets (interval-counters), simlar to those defined in [TR-159] are
implemented using the textual conventions defined in the HC-PerfHist-
TC-MIB [RFC3705]. The HC-PerfHist-TC-MIB defines 64-bit versions of
the textual conventions found in PerfHist-TC-MIB [RFC3593].
The agent SHOULD align the beginning of each interval to a fifteen
minute boundary of a wall clock. Likewise, the beginning of each one
day intervals SHOULD be aligned with the start of a day.
Counters are not reset when a G.Bond TDIM port is reinitialized, but
rather only when the agent is reset or reinitialized (or under
specific request outside the scope of this MIB module).
5.5. Mapping of Broadband Forum TR-159 and ITU-T G.998.3 Managed
Objects
This section contains the mapping between relevant managed objects
(attributes) defined in [TR-159] and managed objects defined in this
document. Note that all management objects defined in [G.998.3] have
corresponding objects in [TR-159].

7. Security Considerations
There is a number of managed objects defined in the GBOND-TDIM-MIB
module that have a MAX-ACCESS clause of read-write or read-create.
Most objects are writeable only when the link is down. Writing to
these objects can have potentially disruptive effects on network
operation, for example:
o Changing of gBondTdimServiceTable configuration paratemers (e.g.
gBondTdimServiceType or gBondTdimServiceSize) MAY lead to a
potential service impairment, for example a TDM service would be
dropped if there is not enough actual bandwidth on the bonded link
to support this service.
o Changing of gBondTdimPortConfTable configuration parameters (e.g.
gBondTdimFecAdminState) MAY lead to anything from link quality and
rate degradation to a complete link initialization failure.
The user of the GBOND-TDIM-MIB module must therefore be aware that
support for SET operations in a non-secure environment without proper
protection can have a negative effect on network operations.
The readable objects in the GBOND-TDIM-MIB module (i.e., those with
MAX-ACCESS other than not-accessible) may be considered sensitive in
some environments since, collectively, they provide information about
the performance of network interfaces and can reveal some aspects of
their configuration.
In such environments it is important to control also GET and NOTIFY
access to these objects and possibly even to encrypt their values
when sending them over the network via SNMP.
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPSec),
even then, there is no control as to who on the secure network is
Beili Expires February 18, 2010 [Page 46]
Internet-Draft G.Bond/TDIM MIB August 2009
allowed to access and GET/SET (read/change/create/delete) the objects
in this MIB module.
It is RECOMMENDED that implementers consider the security features as
provided by the SNMPv3 framework (see [RFC3410], section 8),
including full support for the SNMPv3 cryptographic mechanisms (for
authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an
instance of this MIB module is properly configured to give access to
the objects only to those principals (users) that have legitimate
rights to indeed GET or SET (change/create/delete) them.
8. IANA Considerations
An object identifier for gBondTdimMIB MODULE-IDENTITY SHALL be
allocated by IANA [1] in the MIB-2 transmission sub-tree, before this
document is published as an RFC.
