RFC 1514 (http://www.ietf.org/rfc/rfc1514.txt) dictates that, "The Internet-standard Network Management Framework consists of three [four] components. They are: STD 16, RFC 1155 [1] which defines the SMI, the mechanisms used for describing and naming objects for the purpose of management. http://www.ietf.org/rfc/rfc1155.txt; STD 16, RFC 1212 [2] defines a more concise description mechanism, which is wholly consistent with the SMI. http://www.ietf.org/rfc/rfc1212.txt; STD 17, RFC 1213 [3] which defines MIB-II, the core set of managed objects for the Internet suite of protocols.; STD 15, RFC 1157 [4] which defines the SNMP, the protocol used for network access to managed objects."
