Internet Protocol (IP)
Internet Protocol (IP). The Internet standard protocol that defines the Internet datagram as
the unit of information passed across the Internet, and that provides the basis for the
Internet connectionless, best-effort packet delivery service.
International Organization for Standardization (ISO). A United Nations organization,
established to promote the development of standards to facilitate the international
exchange of goods and services and to develop mutual cooperation in areas of
intellectual, scientific, technological, and economic activity.
interoperability. The ability of software and hardware on multiple machines from multiple
vendors to communicate meaningfully.
IPv4 address. A 32-bit Internet address assigned to a host participating in the Internet using
TCP/IP. Internet addresses are the abstraction of physical hardware addresses, just
as the Internet is an abstraction of physical networks. An IPv4 address consists of a
network portion and a host portion. The address is assigned to the interconnection of a
host to a physical network.
IPv6 address. A 128-bit Internet address assigned to hosts participating in the Internet
using TCP/IP. Internet addresses are the abstraction of physical hardware addresses,
just as the Internet is an abstraction of physical networks. An IPv6 address consists of
a prefix and an interface ID. The address is assigned to the interconnection of a host to
a physical network.
Level 2. A reference to link level communication (for example, frame formats) or link-level
connections derived from the ISO 7-layer reference model. For long-haul networks,
level 2 refers to the communication between a host computer and a network packet
switch (for example, HDLC/LAPB). For local area networks, level 2 refers to physical
packet transmission. Thus, a level 2 address is a physical hardware address.
Level 3. A reference to network level communication derived from the ISO 7-layer reference
model. For the Internet, level 3 refers to the IP and IP datagram formats. Thus, a level
3 address is an Internet address.
Local Area Network (LAN). Any physical network technology that operates at high speed
(usually tens of megabits per second through several gigabits per second) over short
distances (up to a few thousand meters).
management applications. In DSM, an application process that opens a management or
subsystem process to control a subsystem. This process can issue SPI commands to
subsystems and retrieve EMS event messages to assist in the management of a
computer system or a network of systems. A management application is a requester to
the subsystems to which it sends commands; the subsystems are servers to the
management application.
Med
ia Access Control Address (MAC). A 12-digit hexadecimal number. Each TLAM
controller is assigned a unique MAC address, which is burned into its PROM as part of
the manufacturing process. HP, like other manufacturers of IEEE 802.3 controllers, is
