<font face="Arial" size="2">To allow for interoperability of management across
many different network platforms, network management standards are
required so that vendors can implement and adhere to these standards.
Two main standards have emerged:
<img border="0" src="../../images/1.gif" align="absmiddle" width="12" height="12"></font><ul>
<li>
<font face="Arial" size="2"><b>Simple Network Management Protocol</b> � IETF community</font></li>
<li>
<font face="Arial" size="2"><b>Common Management Information Protocol</b>
� Telecommunications community</font></li>
</ul>
<p>
<font face="Arial" size="2">Simple Network Management Protocol (SNMP)
actually refers to a set of standards for network management,
including a protocol, a database structure specification, and a set of
data objects. SNMP was adopted as the standard for TCP/IP internets in
1989 and became very popular. An upgrade, known as SNMP version 2c
(SNMPv2c) was adopted in 1993. SNMPv2c provides support for
centralized and distributed network management strategies, and
included improvements in the structure of management information (SMI),
protocol operations, management architecture, and security. This was designed to run on OSI based
networks as well as TCP/IP based networks. Since then SNMPv3 has been
released. To solve the security shortcomings of SNMPv1 and SNMPv2c,
SNMPv3 provides secure access to MIBs by authenticating and
encrypting packets over the network. The common management information
protocol (CMIP) is an OSI network management protocol that was created
and standardized by the ISO for the monitoring and control of
heterogeneous networks.</font></p>
