30.13 Summary

Network management protocols allow a manager to monitor and control routers and hosts. A Network Management client program executing on the manager's workstation contacts one or more servers, called agents, RU Nning on the devices to be controlled. Because an internet consists of heterogeneous machines and networks, TCP/LP management software executes as application PR Ograms and uses Internet transport protocols (e.g., UDP) for communication between clients and servers.

A set of companion standards to SNMP define the set of variables that a managed entity maintains. The set of variables comprise a Management information Base (MIB). MIB variables is described using ASN.1, a formal language that provides a concise encoded form as well as a precise human -readable notation for names and objects. ASN.1 uses a hierarchical namespace to guarantee the all MIB names is globally unique while still allowing subgroups to Assign parts of the namespace.
