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]. 2. Overview An "RTP System" may be a host end-system that runs an application program that sends or receives RTP data packets, or it may be an intermediate-system that forwards RTP packets. RTP Control Protocol (RTCP) packets are sent by senders and receivers to convey information about RTP packet transmission and reception [RFC3550]. RTCP Extended Report (XR) [RFC3611] packets are sent by receivers to convey additional information about certain types of RTP packet reception. 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 RFC 2119. 2.1 Components The RTCP XR MIB is structured around "Session", "Source", "Destination" and "Receiver" conceptual abstractions. Clark Expires August 2005 [Page 2] draft-ietf-avt-rtcp-xr-mib-01.txt February 2005 2.1.1 An RTP Session is an association of two or more participants communicating with RTP. For each participant, the session is defined by a particular pair of destination transport addresses (one network address plus a port pair for RTP and RTCP). The destination transport addresses may be common for all participants, as in the case of IP multicast, or may be different for each, as in the case of individual unicast addresses plus a common port pair," as defined in section 3 of [RFC3550]. 2.1.2 A "Sender" is identified within an RTP session by a 32-bit numeric "Synchronization Source," or "SSRC", value and is "...the source of a stream of RTP packets" as defined in section 3 of [RFC3550]. The sender is also a source of RTCP Sender Report packets as specified in section 6 of [RFC3550]. 2.1.3 A "Receiver" of a "stream of RTP packets" can be a unicast or multicast Receiver as described in 2.1.1, above. An RTP Receiver has an SSRC value that is unique to the session. An RTP Receiver is a source of RTCP Receiver Reports as specified in section 6 of [RFC3550] and RTCP XR VoIP Metrics Reports as specified in section 4.7 of [RFC3611]. 2.2 Applicability of the MIB to RTP System Implementations 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 systems) or in intermediate systems. 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 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 a "help-desk" scenario. 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 collect Voice over IP session statistical data; these data may be used by a network manager for planning and other network-management purposes. A Monitor may use the RTCP XR MIB to collect data to permit a network manager to diagnose faults in VoIP sessions. 2.3 The Structure of the RTCP XR MIB There are four tables in the RTCP XR MIB The rtcpXrSessionIDtable contains identifying information about each session and about the source and destination. The rtcpXrBasicParametersTable contains basic packet loss, discard and delay related parameters about a session. The rtcpXrVoiceQualityMetricTable contains information about the call quality of a session Clark Expires August 2005 [Page 3] draft-ietf-avt-rtcp-xr-mib-01.txt February 2005 The rtcpXrHistoryTable contains aggregate information about a group of sessions. 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.

Security Considerations Certain MIB objects contain endpoint identifying information: rtcpXrSessionIDSourceIPaddress rtcpXrSessionIDDestIPaddress rtcpXrSessionIDSrceIdentifier rtcpXrSessionIDDestIdentifier 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. Access to rtcpXrHistoryReset can result in resetting the table of aggregate call quality information, which results in the loss of useful management data. 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. 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. 5. IANA Considerations An OID within the mib-2 tree is requested, following which this note may be deleted. 6.
