NTP – Network Time Protocol: A network time distribution protocol developed at the University of
Delaware under the direction of Dr. Mills. NTP is a client / server based protocol where the server is the
supplier of time and the client is the consumer of the time information.
Private Enterprise MIB: SNMP allows private organizations to define their own MIB extensions. The
IANA of the IETF issues, for a fee, a unique number to an organization that is an address entry point
from the MIB II into the private data for that organization. Only one Enterprise address is assigned to an
organization. The Enterprise address for Symmetricom is 1896. This address space has grown to over
12,000 private addresses and Symmetricom is by comparison one of the earlier adopters of SNMP with
an Enterprise MIB!
RFC – Request for Comments: A document reviewed and released by the IANA that defines the formal
definitions of various Internet communication protocols and related information.
SNMP – Simple Network Management Protocol: This Internet communications protocol is used for
the status and control of remote network devices. Numerous IANA standards committees starting in
1990 and continuing to day define this protocol.
Trap or Trap Message: A packet issued from an SNMP Management agent to an SNMP Management
station. The message is intended to relay and important even that occurred within the agent that requires
attention or notification.
