The agent retrieves the requested value from a database stored in the managed device and sends the reply. SNMP agents often retrieve and reply with statistics about the managed device. Examples include utilization values on ports, address tables that are stored, and vendor profiles. The protocol used to communicate the information is the Simple Network Management Protocol (SNMP).

Type of Service A field in an IP packet that controls the quality of service that the packet requires.

If the network equipment supports better service i.e. VoIP, the better service will be provided.
