Protocol Data Unit. A message containing protocol-specific information.
The continuous process by which NMS solicits network information.
Point-to-Point Protocol. A protocol for packet transmission over serial links, specified by
Internet RFC 1661.
Permanent Virtual Circuit. A connection established administratively and used to support
ATM, frame relay, and X.25.
Rate Adaptive Digital Subscriber Line. A technique for the use of an existing twisted-pair
line that permits simultaneous POTS and high-speed data communication at adaptive
symmetric and asymmetric rates.
A device that connects LANs by dynamically routing data according to destination and
available routes.
A table used by a node to route traffic to another node in the multiplexer network.
Severely Errored Seconds. Usually defined as a second during which a specific number of
CRC errors was exceeded, or an OOF or other critical error occurred.
A command providing write access to SNMP MIB objects.
Service Level Verifier. A feature that monitors and ensures frame relay network service.
Simple Network Management Protocol. Protocol for open networking management.
A display of connection of devices. A submap may be developed by the HP OpenView
using the autodiscovery feature, or it may be created by the user.
A portion of a network, which may be a physically independent network segment, that
shares a network address with other portions of the network and is distinguished by a
subnet number. A subnet is to a network what a network is to an internet.
A number that identifies the subnet portion of a network address. The subnet mask is a
32-bit Internet address written in dotted-decimal notation with all 1s in the network and
subnet portions of the address.
A term for a digital carrier facility used to transmit a DS1 formatted digital signal at
1.544 Mbps. It is used primarily in North America.
Transmission Control Protocol/Internet Protocol. The dominant protocol suite in the
worldwide Internet, TCP allows a process on one machine to send data to a process on
another machine using the IP. TCP can be used as a full-duplex or one-way simplex
connection.
Virtual terminal protocol in the Internet suite of protocols. Allows the user of one host
computer to log into a remote host computer and interact as a normal terminal user.
Trivial File Transfer Protocol. A standard TCP/IP protocol that allows simple file transfer to
and from a remote system without directory or file listing. TFTP is user where FTP is not
