Internet-Draft G.Bond/TDIM MIB February 2012
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 (or individual bearer channels in
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", "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 August 12, 2012 [Page 3]
Internet-Draft G.Bond/TDIM MIB February 2012
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, as
well as xDSL lines/channels, in a managed 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 it describes the bonding management, bonded 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, structured as recommended by RFC 4181
[RFC4181]:
o gBondTdimPortNotifications - containing notifications (TDIM
Service Down/Up).
o gBondTdimPortConfTable - containing objects for configuration of a
G.Bond/TDIM port.
o gBondTdimPortCapTable - containing objects reflecting capability
of a G.Bond/TDIM port.
o gBondTdimPortStatTable - containing objects providing overall
status information of a G.Bond/TDIM port, complementing the
generic status information from the ifTable of IF-MIB and
gBondPortStatFltStatus of GBOND-MIB.
o gBondTdimSvcTable - 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 August 12, 2012 [Page 4]
Internet-Draft G.Bond/TDIM MIB February 2012
5.2. Link 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 query 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 gBondTdimPortConfTable
(gBondTdimPortConfAdminServices), gBondTdimSvcTable and
gBondTdimOperSvcTable can be used to configure and query the
configuration of services transported via the G.Bond/TDIM link. The
services may be configured independently of the link state (i.e. in-
and out-of-service), as G.998.3 communicates changes in the service
configuration via specific Bonding Communication Channel (BCC)
messages, switching both ends of the link to the new configuration
synchronously.
There can be up to 60 active services defined on a G.Bond/TDIM link.
This MIB module provides an ability to define up to 255 services via
the gBondTdimSvcTable, with each row representing a possible service,
and then set the actual service configuration using the
gBondTdimPortConfAdminServices object (a byte-vector of service
indices), listing the active services in the order of their position
in the G.Bond/TDIM frame. This design allows one to easily modify
service drop priority, which directly corresponds to the service
position.
The actual list of services is provided via the read-only
gBondTdimOperSvcTable, where each entry's index corresponds to the
service position, starting from index 1 for the first entry, 2 for
the second entry etc., providing an easy service navigation for a
management application using GET-NEXT (instead of counting bytes in
the gBondTdimPortConfAdminServices object).
The service configuration can only be changed on a Bonding
Beili Expires August 12, 2012 [Page 5]
Internet-Draft G.Bond/TDIM MIB February 2012
Transmission Unit at the Central Office (BTU-C).
When configuring the services, please bear in mind that 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 and service drop priority during
bandwidth degradation
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].
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) positioned in the beginning of the
G.Bond/TDIM frame, have higher priority than asynchronous services
(Ethernet, ATM, GFP encapsulated), positioned farther away. Within
the services of the same type, those with lower position (index) have
higher priority.
5.3.2. Service Notifications
This MIB module provides specific Up/Down notifications
(gBondTdimSvcUp/gBondTdimSvcDown) for each of the configured
services. During bandwidth degradation a number of services may be
suspended (dropped) simultaneously, according to their drop priority
(position in the service list). Please note that it is possible for
a higher priority service to be dropped before a lower priority one.
For example, suppose there are two services configured on a 2 Mbps
G.Bond/TDIM link: a T1 service (gBondTdimSvcType with a value of ds1,
with a bandwidth requirement of 1.5 Mbps) and an Ethernet service
with a size of 0.5 Mbps. When the actual link bandwidth is reduced
to 1.4 Mbps, the T1 service with a gBondTdimOperSvcPosition value of
1 would be dropped, while the Ethernet service with a
gBondTdimPerSvcPosition value of 2 would remain up.
Notifications SHOULD be rate-limited (throttled) such that there is
an implementation-specific gap between the generation of consecutive
notifications of the same event. This mechanism prevents
notification flooding in case gBondTdimServiceOperState oscillates
between Up and Down states. When notifications are rate-limited,
they are dropped and not queued for sending at a future time. This
is intended to be a general rate-limiting statement for notifications
Beili Expires August 12, 2012 [Page 6]
Internet-Draft G.Bond/TDIM MIB February 2012
that otherwise have no explicit rate-limiting assertions in this
document.
5.4. Performance Monitoring
The OPTIONAL performance monitoring counters, thresholds and history
buckets (interval-counters), similar 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.
Note that the accumulation of certain performance events for a
monitored entity is inhibited (counting stops) during periods of
service unavailability on that entity. The DESCRIPTION clause of
performance monitoring counters in this MIB module specifies which of
the counters are inhibited during periods of service unavailability.
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].

Table 1: Mapping of TR-159 Managed Objects
Note that some of the mapping between the objects defined in TR-159
and the ones defined in this MIB module is not one-to-one, for
example, while TR-159 PM attributes aGroupPerf* map to the
corresponding gBondPortPm* objects of the GBOND-MIB module, there are
no dedicated PM attributes for the gBondTdimPortPm* and
gBondTdimSvcPm* objects introduced in this MIB module. However,
since their definition is identical to the definition of gBondPortPm*
objects of the GBOND-MIB module, we can map gBondTdimPortPm* and
gBondTdimSvcPm* to the relevant aGroupPerf* attributes of TR-159 and
use the term 'partial mapping' to denote the fact that this mapping
is not one-to-one.

The value of this object is a concatenation of zero or more (up
to 60) octets, where each octet contains an 8-bit
GBondTdimSvcIndex value, identifying a particular service.
An octet's position reflects the associated service position
and its priority in the G.Bond/TDIM frame, with 1st octet being
the 1st service of highest priority.
A zero-length octet string is object-specific and MUST
therefore be defined as part of the description of any object
that uses this syntax. Examples of the usage of a zero-length
value might include situations where an object using this
textual convention is irrelevant for a specific G.Bond/TDIM port
type or that no services have been defined for this port."

was actually monitored. This value will be the same as the
interval duration (86400 seconds), except in a situation where
performance data could not be collected for any reason.
This object partially maps to the TR-159 attribute
aGroupPerf1DayIntervalMoniSecs."

DESCRIPTION
"A read-only object indicating whether or not this history
bucket contains valid data. Valid bucket is reported as true(1)
and invalid bucket as false(2).
If this history bucket is invalid the BTU-C MUST NOT produce
notifications based upon the value of the counters in this
bucket.
Note that an implementation may decide not to store invalid
history buckets in its data base. In such case this object is
not required as only valid history buckets are available while
invalid history buckets are simply not in the data base.
This object partially maps to the TR-159 attribute
aGroupPerf1DayIntervalValid."

7. Security Considerations
There is a number of managed objects defined in this MIB module with
a MAX-ACCESS clause of read-write and/or read-create. Such objects
may be considered sensitive or vulnerable in some network
environments. The support for SET operations in a non-secure
environment without proper protection can have a negative effect on
network operations. These are the tables and objects and their
sensitivity/vulnerability:
o Changing of gBondTdimPortConfAdminServices object may lead to a
potential service disruption, by changing a particular service'
position (therefore changing its drop priority) or even removing
the service from the link altogether.
o Changing of gBondTdimSvcTable configuration parameters (e.g.
gBondTdimSvcType or gBondTdimSvcSize) 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.
gBondTdimPortConfFecAdminState) may lead to anything from link
quality and rate degradation to a complete link initialization
failure.
Some of the readable objects in this MIB module (i.e., those with
MAX-ACCESS other than not-accessible) may be considered sensitive or
vulnerable in some network environments since, collectively, they
provide information about the performance of network interfaces and
can reveal some aspects of their configuration.
In particular, since a bonded xDSL port can be comprised of multiple
Unshielded Twisted Pair (UTP) voice grade copper, located in the same
bundle with other pairs belonging to another operator/customer, it is
theoretically possible to eavesdrop to a G.Bond transmission, simply
Beili Expires August 12, 2012 [Page 50]
Internet-Draft G.Bond/TDIM MIB February 2012
by "listening" to a cross-talk from the bonded pairs, especially if
the operating parameters of the G.Bond link in question are known.
It is thus important to control even GET and/or NOTIFY access to
these objects and possibly even encrypt the values of these objects
when sending them over the network via SNMP. These are the tables
and objects and their sensitivity/vulnerability:
o gBondTdimPortStatFecOperState in gBondTdimPortStatTable indicate
whether the FEC function is enabled, which may aid in deciphering
of the G.Bond/TDIM transmissions.
o gBondTdimOperSvcTable provide current operational service
configuration, which may aid in deciphering of the G.Bond/TDIM
transmissions.
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPSec),
there is no control as to who on the secure network is allowed to
access and GET/SET (read/change/create/delete) the objects in this
MIB module.
Implementations MUST provide the security features described by the
SNMPv3 framework (see [RFC3410]), including full support for
authentication and privacy via the User-based Security Model (USM)
[RFC3414] with the AES cipher algorithm [RFC3826]. Implementations
MAY also provide support for the Transport Security Model (TSM)
[RFC5591] in combination with a secure transport such as SSH
[RFC5592] or TLS/DTLS [RFC6353].
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.
