                 SNMP Architecture
   several (potentially many) nodes, each with an SNMP entity
    containing command responder and notification originator
    applications, which have access to manage-ment
    instrumentation (traditionally called agents);
   at least one SNMP entity containing command generator
    and/or notification receiver applications (traditionally called a
    manager) and,
   a management protocol used to convey management
    information between the SNMP entities.

         Authoritative Engine
   When an SNMP message contains a payload that expects a
    response (for example, a Get, GetNext, GetBulk, Set, or
    Inform PDU), then the receiver of such messages is
    authoritative.
   When an SNMP message contains a payload that does not
    expect a response (for example, an SNMPv2-Trap,
    Response, or Report PDU), then the sender of such a
    message is authoritative.
