internet is two or more networks connected by an internal or external router. The
word “internet” is a generic term. “The Internet” is the world’s largest internet.
Interswitch Link (ISL)
Interswitch Link. An Avaya proprietary mechanism to tag packets with VLAN and
priority information across the backbone. This allows two Avaya devices to act as a
single logical entity.
IP
The protocol that governs packet forwarding within the TCP/IP standards
developed and used on the Internet. Refer to TCP/IP on page 254.
IP Address
A 32-bit address assigned to hosts using TCP/IP. An IP address is written as 4 octets
separated by periods (dotted decimal format). Each address consists of a network
number, an optional subnetwork number, and a host number. The network and
subnetwork numbers together are used for routing, while the host number is used
to address an individual host within the network or subnetwork. A subnet mask is
used to extract network and subnetwork information from the IP address.
IPX

from servers to workstations. IPX is primarily used in Novell NetWare operating
systems.
ISL
Interswitch Link. An Avaya proprietary mechanism to tag packets with VLAN and
priority information across the backbone. This allows two Avaya devices to act as a
single logical entity.
ISO
International Standards Organization. A voluntary organization founded in 1946,
responsible for creating international standards in many areas, including computers
and communications.
Jabber
An error condition in which a network device continually transmits random,
meaningless data onto the network. In IEEE 802.3, Jabber refers to a data packet, the
length of which exceeds the maximum length prescribed in the standard.
