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
[RFC2819]. In particular, it describes managed objects used for
realtime application QOS monitoring.

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 defines a method of sorting the interfaces of a
monitored device according to values of parameters specific to this
interface.
The original RAQMON draft [SIDDIQUI1] was split into 3 parts to
identify the RAQMON Framework, RAQMON QOS PDU and RAQMON MIB.
This memo defines 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 [RFC2819] to
accommodate RAQMON solution.
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
RMON MIB WG Expires July 2003 [Page 2]
INTERNET DRAFT RAQMON MIB January 2003
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 [SIDDIQUI2] the RAQMON framework is based on three
entities:
- RAQMON Data Source (RDS) - RAQMON Report Collector (RRC) - RAQMON
MIB Structure
Figure 1 below shows various interfaces in RAQMON Framework. This
draft specifies the Management Information Base (MIB) Modules used by
the RAQMON Report Collectors to store data derived from RAQMON PDUs.

(3) Device State Specific Metrics
(4) RAQMON PDU transmitted over this interface (IP Address, port)
(5) RAQMON MIB running between RRCs and a RAQMON Application ('RAQMON manager')
4. Structure of the RAQMON MIB
The RAQMON MIB is composed of three MIB groups:
The raqmonSession MIB group incorporates the following tables:
- raqmonParticpantTable contains information about participants in open and closed (terminated) sessions
- raqmonQosTable contains historical information about QoS during sessions
- raqmonParticpantAddrTable maps particpant addresses into the index of the raqmonParticpantTable
The raqmonException MIB group includes a table of filters that trigger notifications for sessions with poor QoS.
The raqmonConfig MIB group includes object that define the configuration of the RAQMON collector.
All objects in the MIB MUST be implemented by the RAQMON collectors, with the exception of the raqmonPDUBasicPDU object and raqmonSNMPTransportNotification which MUST be implemented by a RAQMON device. This is reflected in the conformance clauses.

9. Security Considerations
There are a number of management objects defined in this MIB
that have 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.
There are a number of managed objects in this MIB that may contain
RMON MIB WG Expires July 2003 [Page 26]
INTERNET DRAFT RAQMON MIB January 2003
sensitive information. These are:
raqmonParticipantAddr
It is thus important to control even GET access to these objects
and possibly to even encrypt the values of these object when
sending them over the network via SNMP. Not all versions of
SNMP provide features for such a secure environment.
SNMPv1 by itself is not a secure environment. 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.
It is RECOMMENDED that the implementers consider the security
features as provided by the SNMPv3 framework. Specifically, the
use of the User-based Security Model [RFC2274] and the
View-based Access Control Model [RFC2275] is RECOMMENDED.
It is then a customer/user responsibility to ensure that the SNMP
entity giving access to an instance of this MIB, 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.
