Abstract

This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
The document proposes an extension to the Remote Monitoring MIB, RFC
2819. In particular, it describes managed objects used for real-time
application Quality of Service (QoS) monitoring.

RFC 4711 RAQMON MIB October 2006

1. Introduction

This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it extends [RFC2819] with managed objects used for
real-time application QoS monitoring.

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 [RFC2119].

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].

3. RAQMON Framework

As outlined in [RFC4710], the RAQMON framework is based on three
entities:

- RAQMON Data Source (RDS)

- RAQMON Report Collector (RRC)

- RAQMON MIB Structure

The RAQMON MIB describes information passed between RRCs and a RAQMON
Application ("RAQMON manager").

4. Structure of the RAQMON MIB

The RAQMON MIB module is composed of three MIB groups:
raqmonSession, raqmonException, and raqmonConfig.

The raqmonSession MIB group incorporates the following tables:

Siddiqui, et al. Standards Track [Page 2]

RFC 4711 RAQMON MIB October 2006

- The raqmonParticpantTable contains information about
participants in open and closed (terminated) sessions, including
parameters of the sessions they are involved in, aggregated
since the beginning of the session.

- The raqmonQosTable contains historical information about QoS
during sessions. The set of parameters represented in this
table is more restricted, but it includes historical per-
RAQMON-report information.

- The raqmonParticpantAddrTable maps participant addresses into
the indices of the raqmonParticpantTable. This table allows
management applications to find entries sorted by
raqmonParticipantAddr rather than raqmonParticipantStartDate.

The raqmonException MIB group includes a table of filters that
trigger notifications for sessions with poor QoS.

The raqmonConfig MIB group includes objects that define the
configuration of the RAQMON Report Collector.

This MIB module MUST be implemented by RAQMON Report Collectors.

A separate MIB module is defined in [RFC4712] for mapping the RAQMON
PDUs onto an SNMP transport. The MIB module defined in [RFC4712] is
normally implemented by RAQMON Data Sources (RDS).

5. RAQMON MIB Definitions

The MIB module herein IMPORTS definitions from the following:
SNMPv2-SMI [RFC2578]
SNMPv2-TC [RFC2579]
SNMPv2-CONF [RFC2580]
RMON-MIB [RFC2819]
SNMP-FRAMEWORK-MIB [RFC3411]
INET-ADDRESS-MIB [RFC4001]

It also uses REFERENCE clauses to refer to [RFC4710].

It also mentions [RFC3737] with respect to the MODULE-IDENTITY OID
allocation.

6. Security Considerations

There are a number of management objects defined in this MIB module
with a MAX-ACCESS clause of read-write. 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.

Setting the value of the object raqmonRDSTimeout to too low a value
would result in RDS sessions being terminated sooner than necessary,
while setting at too high a value may result in terminated sessions
continuing to be managed, with unnecessary memory allocations.

Siddiqui, et al. Standards Track [Page 33]

RFC 4711 RAQMON MIB October 2006

Setting the following object to incorrect values can result in the
collectors either flooding the management applications with
unnecessary notifications, or not sending notifications when the QoS
in the network may be degraded.

raqmonSessionExceptionIAJitterThreshold
raqmonSessionExceptionRTTThreshold
raqmonSessionExceptionLostPacketsThreshold

Setting the raqmonConfigPort object to incorrect values can result in
the collector not being able to receive RAQMON PDUs from the data
sources.

Some of the readable objects in this MIB module (i.e., objects with a
MAX-ACCESS other than not-accessible) may be considered sensitive or
vulnerable in some network environments. These are:

raqmonParticipantTable
raqmonQoSTable
raqmonParticpantAddrTable

Unauthorized exposure of these objects may lead to disclosure of the
addresses of the participants in applications, or information about
the traffic patents of the applications, which may be considered
sensitive in certain environments.

It is thus important to control even GET and/or NOTIFY access to
these objects and possibly to even encrypt their values when sending
them over the network via SNMP.

The structure of the RAQMON tables limits what can be usefully done
for access control configuration using View-based Access Control
Model (VACM). For example, with these structures it would not be
possible to provide a group, with access to performance data for a
specific group of devices, since the index values for
raqmonParticpantEntry cannot be known in advance. Likewise,
raqmonSessionExceptionEntries apply to all entries in the
raqmonQoSTable.

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
allowed to access and GET/SET (read/change/create/delete) the objects
in this MIB module.

RFC 4711 RAQMON MIB October 2006

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.

7. IANA Considerations

No requirements from IANA are defined in this document. The root OID
of the MIB module defined in this document belongs to the RMON
subtree, as reserved in [RFC3737].
