The focus of this chapter was on the main RMON functions and extensions. However, other RFCs produced by the IETF RMON working group are worth mentioning, either for reference or for further investigation:
RFC 3919, Remote Network Monitoring (RMON) Protocol Identifiers for IPv6 and Multi Protocol Label Switching (MPLS)
This informational RFC defines basic protocol identifiers for IP version 6 and MPLS protocols. RFC 2896, Remote Network Monitoring MIB Protocol Identifier Macros, defines various protocol identifiers, and RFC 2895 defines the syntax of the protocol identifier descriptors. The intent of this document is not to adapt each protocol identifier defined in RFC 2895 and in RFC 2896 for IP version 6, but to define protocol identifiers for IP version 6 protocols and for MPLS protocol. Note that this RFC is informational only, which means that it is not a standard definition.
RFC 3577, Introduction to the Remote Monitoring (RMON) Family of MIB Modules
This informational RFC provides a very useful tutorial about RMON objectives, foundations, architecture, various extensions, and relationship information to other MIBs.
RFC 4149, Definition of Managed Objects for Synthetic Sources for Performance Monitoring Algorithms
This RFC defines a method of describing Synthetic Sources for Performance Monitoring (SSPM). This is useful within the RMON framework for performance monitoring in cases where it is desirable to inject packets into the network for monitoring their performance with the other MIBs in that framework.
RFC 4150, Transport Performance Metrics MIB
This RFC continues the architecture created in the RMON 2-MIB (RFC 2021) by providing a major feature upgrade. It primarily provides new metrics and studies to help analyze performance for subapplication transactions in the network, in direct relationship to the transporting of application layer protocols. The monitoring covers both passive and active traffic generation sources.
RFC 4710, Real-time Application Quality-of-Service Monitoring (RAQMON) Framework
RAQMON allows end devices and applications to report QoS statistics in real time. There is a need to monitor end devices such as IP phones, pagers, instant messaging clients, mobile phones, and various other handheld computing devices. This RFC extends the RMON family of specifications to allow real-time QoS monitoring of various applications that run on these devices. It also allows this information to be integrated with the RMON family using Simple Network Management Protocol (SNMP). The companion RFCs are RFC 4711, Real-time Application Quality-of-Service Monitoring (RAQMON) MIB, and RFC 4712, Transport Mappings for Real-time Application Quality-of-Service Monitoring (RAQMON) Protocol Data Unit (PDU).
