IP multicast A technique for routing that enables IP traffic to be reproduced
from one source to several endpoints or from multiple sources to
many destinations. Instead of transmitting only one packet to each individual
point of destination, one packet is sent to a multicast group specified
by only one IP endpoint address for the group.
IPX Internetwork Packet Exchange: Network layer protocol (Layer 3) used
in Novell NetWare networks for transferring information from servers to
workstations. Similar to IP and XNS.
IPXCP IPX Control Program: The protocol used to establish and configure
IPX over PPP. See also: IPX and PPP.
IPXWAN Protocol used for new WAN links to provide and negotiate line
options on the link using IPX. After the link is up and the options have been
agreed upon by the two end-to-end links, normal IPX transmission begins.
ISDN Integrated Services Digital Network: Offered as a service by telephone
companies, a communication protocol that allows telephone networks
to carry data, voice, and other digital traffic. See also: BISDN, BRI,
and PRI.
ISL routing Inter-Switch Link routing is a Cisco proprietary method of
frame tagging in a switched internetwork. Frame tagging is a way to identify
the VLAN membership of a frame as it traverses a switched internetwork.
isochronous transmission Asynchronous data transfer over a synchronous
data link, requiring a constant bit rate for reliable transport. Compare
with: asynchronous transmission and synchronous transmission.
ITU-T International Telecommunication Union Telecommunication Standardization
Sector: This is a group of engineers that develops worldwide
standards for telecommunications technologies.
LAN Local Area Network: Broadly, any network linking two or more computers
and related devices within a limited geographical area (up to a few
kilometers). LANs are typically high-speed, low-error networks within a
company. Cabling and signaling at the Physical and Data Link layers of the
OSI are dictated by LAN standards. Ethernet, FDDI, and Token Ring are
among the most popular LAN technologies. Compare with: MAN.
