MIBs
In a TCP/IP-based network, each device maintains a set of variables describing its state. In SNMP, these variables are known as objects, but these objects do not hold the same meaning as those within an object-oriented programming architecture. SNMP objects contain information about their state without any methods, other than the ability to read and write their values.

Network Services Monitoring MIB
SIP MIBs
