HP TCP/IP
communicate with other systems and with workstations over local area networks based
on the IEEE 802.3 and Ethernet II standards. The pre-G-series HP TCP/IP
communications product uses TLAM.
HP TCP/IP. HP’s implementation of TCP/IP. HP TCP/IP provides TCP/IP connections for the
NonStop system. HP TCP/IP connects the NonStop system to a variety of systems,
including the Integrity S2 (HP’s fault-tolerant UNIX system) and systems manufactured
by other vendors. Cooperative applications can partition functions to use the strengths
of the different operating systems. Applications running on a NonStop system or an
Expand network can transparently exchange data with TCP/IP devices.
TCP. See Transmission Control Protocol.
TCP group. The group in MIB-II supported by the TCP/IP Subagent that provides
information about the TCP layer of a TCP/IP subsystem being managed.
TCPIPSA. The name of the executable file for the TCP/IP Subagent.
TCP/IP Subagent. The NonStop subagent that implements MIB-II groups, enabling
management of TCP/IP subsystems.
template. An EMS object used to specify how to format event messages that need to be
read as text.
TESTSEND. An NCL file that sends a predefined trap to a specified SNMP manager. This
trap has values for all eight objects defined in the EMS Trap MIB.
TLAM. See Tandem LAN Access Method.
token. In SPI, a distinguishable unit in an SPI message. The SNMP agent and subagents
use values supplied in tokens to derive MIB object values.
Transmission Control Protocol. The Internet standard transport protocol that provides a
reliable, full-duplex, connection-oriented, stream service used by many application
protocols. One of its main jobs is to recover from traffic that may have been discarded
by the connectionless-type protocol IP. TCP allows a process on one machine to send
a stream of data to a process on another. It is connection-oriented in the sense that
before transmitting data, participants must establish a connection. Software
implementing TCP usually resides on the operating system and uses the IP protocol to
transmit information across the Internet. It is possible to terminate (shut down) one
direction of flow across a TCP connection, leaving a one-way connection. The Internet
protocol suite is often referred to as TCP/IP because TCP is one of the two most
fundamental protocols. This protocol is used by applications that require reliable end-
to-end data transfer. It is a byte-stream-oriented protocol and includes no concept of
packet boundaries. The only guarantee is that all of the data sent will be received in
the same order in which it was sent.
transport layer. The layer of the Internet suite of protocols that describes end-to-end
services.
