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 updates [SIDDIQUI1] that defined 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 memo [SIDDIQUI2] defines a Real-Time Application QOS Monitoring
   (RAQMON) Framework that extends the RMON Framework to allow Real-time
   Application QoS information of these types of end devices as outlined
   by RAQMON Charter of the RMON Workgroup.

   The memo [SIDDIQUI3] takes a portion of <draft-siddiqui-rmonmib-
   raqmon-mib-01.txt> that defined RAQMON QOS PDU and describes how
   various PDUs can be transported over existing Application level
   transport protocol like Real Time Communication Protocol (RTCP) and
   Simple Network Management Protocol (SNMP) to transport statistics
   between RDS and RRC.

   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 SNMP Management Framework

   The SNMP Management Framework presently consists of five major
   components:

   o   An overall architecture, described in RFC 2571 [RFC2571].

   o   Mechanisms for describing and naming objects and events for the
       purpose of management.  The first version of this Structure of
       Management Information (SMI) is called SMIv1 and described in
       STD 16, RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC
       1215 [RFC1215].  The second version, called SMIv2, is described
       in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and
       STD 58, RFC 2580 [RFC2580].

   o   Message protocols for transferring management information.  The
       first version of the SNMP message protocol is called SNMPv1 and
       described in STD 15, RFC 1157 [RFC1157].  A second version of
       the SNMP message protocol, which is not an Internet standards
       track protocol, is called SNMPv2c and described in RFC 1901
       [RFC1901] and RFC 1906 [RFC1906].  The third version of the
       message protocol is called SNMPv3 and described in RFC 1906
       [RFC1906], RFC 2572 [RFC2572] and RFC 2574 [RFC2574].

   o   Protocol operations for accessing management information.  The
       first set of protocol operations and associated PDU formats is
       described in STD 15, RFC 1157 [RFC1157].  A second set of
       protocol operations and associated PDU formats is described in
       RFC 1905 [RFC1905].

   o   A set of fundamental applications described in RFC 2573
       [RFC2573] and the view-based access control mechanism described
       in RFC 2575 [RFC2575].

   A more detailed introduction to the current SNMP Management Framework
   can be found in RFC 2570 [RFC2570].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  Objects in the MIB are
   defined using the mechanisms defined in the SMI.

   This memo specifies a MIB module that is compliant to the SMIv2.  A
   MIB conforming to the SMIv1 can be produced through the appropriate
   translations.  The resulting translated MIB must be semantically
   equivalent, except where objects or events are omitted because no

INTERNET DRAFT                 RAQMON MIB                   October 2002


   translation is possible (use of Counter64).  Some machine readable
   information in SMIv2 will be converted into textual descriptions in
   SMIv1 during the translation process.  However, this loss of machine
   readable information is not considered to change the semantics of the
   MIB.

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.

(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.

8.  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
   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.
