2.1.1 An RTP Session is an association of two or more participants 2.1.1 An RTP Session is an association of two or more participants
communicating with RTP. For each participant, the session is defined communicating with RTP. For each participant, the session is defined
by a particular pair of destination transport addresses (one network by a particular pair of destination transport addresses (one network
address plus a port pair for RTP and RTCP). The destination address plus a port pair for RTP and RTCP). The destination
transport addresses may be common for all participants, as in the transport addresses may be common for all participants, as in the

section 3 of [RFC3550]. section 3 of [RFC3550].
2.1.2 A "Sender" is identified within an RTP session by a 32-bit 2.1.2 A "Sender" is identified within an RTP session by a 32-bit
numeric "Synchronization Source," or "SSRC", value and is "...the numeric "Synchronization Source," or "SSRC", value and is "...the

2.2 Applicability of the MIB to RTP System Implementations 2.2 Applicability of the MIB to RTP System Implementations
The RTCP XR MIB may be used in RTP Host Systems (end systems), see The RTCP XR MIB may be used in RTP Host Systems (end systems), see
section 3 of [RFC3550] that are supporting Voice over IP (VoIP host section 3 of [RFC3550], that are supporting Voice over IP (VoIP host
systems). systems) or in intermediate systems.
2.2.1 VoIP host Systems are end-systems that may use the RTCP XR MIB 2.2.1 VoIP host Systems are end-systems that may use the RTCP XR MIB
to collect RTP Voice over IP session data that the host is sending or to collect RTP Voice over IP session data that the host is sending or
receiving; these data may be used by a network manager to detect and receiving; these data may be used by a network manager to detect and
diagnose faults that occur over the lifetime of a VoIP session as in diagnose faults that occur over the lifetime of a VoIP session as in
a "help-desk" scenario. a "help-desk" scenario.
2.2.2 Monitors of RTP Voice over IP sessions may be third-party or 2.2.2 Monitors of RTP Voice over IP sessions may be third-party or
may be located in the RTP host. Monitors may use the RTCP XR MIB to may be located in the RTP host. Monitors may use the RTCP XR MIB to
collect Voice over IP session statistical data; these data may be collect Voice over IP session statistical data; these data may be
used by a network manager for planning and other network-management used by a network manager for planning and other network-management
purposes. A Monitor may use the RTCP XR MIB to collect data to purposes. A Monitor may use the RTCP XR MIB to collect data to
permit a network manager to diagnose faults in VoIP sessions. permit a network manager to diagnose faults in VoIP sessions.
2.2.3 Many host systems will want to keep track of streams beyond
what they are sending and receiving. In a host monitor system, a
host agent would use RTP data from the host to maintain data about
streams it is sending and receiving, and RTCP data to collect data
about other hosts in the session.

in the rtpSessionTable. In this way the SNMP Set operation MAY
be used to configure a monitor. The rtcpXrBasicParametersTable contains basic packet loss, discard
and delay related parameters about a session.
The rtcpXrVoiceQualityMetricTable contains information about the call

The rtcpXrHistoryTable contains aggregate information about a group

2.4 Relationship to the RAQMON Architecture 2.4 Relationship to the RAQMON Architecture
The Real-time Application QoS monitoring (RAQMON) Framework [xx]
defines an architecture that extends the Remote Monitoring (RMON)
family of applications for monitoring of application QoS in real
time, and an extensible data model with objects carried between
RAQMON data sources and RAQMON collectors. The RAQMON work is
more generic, and complementary in concept to RTCP-XR, covering a
wider range of applications running concurrently, while RTCP-XR
focuses on in-depth QoS monitoring of media traffic in VoIP.
The Real-time Application QoS Monitoring (RAQMON) MIB is defined
by [xx] and runs on RAQMON collectors. A performance monitoring
application may query (i) RAQMON collectors for RAQMON MIB
information about the QoS parameters of multiple concurrent
applications (ii) end-points and gateways for in-depth RTCP-XR
information about the media QoS of VoIP or (iii) both.

4. Security Considerations 4. Security Considerations
In most cases, MIBs are not themselves security risks; if SNMP Certain MIB objects contain endpoint identifying information:
security is operating as intended, the use of a MIB to view
information about a system, or to change some parameter at the
system, is a tool, not a threat.
None of the read-only objects in this MIB reports a password, though rtcpXrSessionIDSourceIPaddress
some SDES [RFC3550] items such as the CNAME [RFC3550], the canonical rtcpXrSessionIDDestIPaddress
name, may be deemed sensitive depending on the security policies of a rtcpXrSessionIDSrceIdentifier
particular enterprise. If access to these objects is not limited by rtcpXrSessionIDDestIdentifier
an appropriate access control policy, these objects can provide an
attacker with information about a system's configuration and the
services that that system is providing. Some enterprises view their
network and system configurations, as well as information about usage
and performance, as corporate assets; such enterprises may wish to
restrict SNMP access to most of the objects in the MIB.
Confidentiality of RTP and RTCP data packets is defined in section 9 Unauthorized exposure of these objects may lead to disclosure of the
of the RTP specification [RFC3550]. Encryption may be performed on addresses of the participants in applications, or information about
RTP packets, RTCP packets, or both. Encryption of RTCP packets may the traffic patents of the applications, which may be considered
pose a problem for third-party monitors though "For RTCP, it is sensitive in certain environments.
allowed to split a compound RTCP packet into two lower-layer packets,
one to be encrypted and one to be sent in the clear. For example,
SDES information might be encrypted while reception reports were sent
in the clear to accommodate third-party monitors [RFC3550]."
SNMPv1 by itself is not a secure environment. Even if the network Access to rtcpXrHistoryReset can result in resetting the table of
itself is secure (for example by using IPSec), there is no control as aggregate call quality information, which results in the loss of
to who on the secure network is allowed to access and GET/SET useful management data.
(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 RFC 2574 [RFC2574] and the View-based
Access Control Model RFC 2575 [RFC2575] 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.
5. Acknowledgements 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.
6. Intellectual Property 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.
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.
