IEEE Std 802.1w-2001
A standard that defines Rapid Spanning Tree Protocol (RSTP) behavior.
IEEE Std 802.1X-2001
A standard that defines port-based network access control behavior.
IETF
Internet Engineering Task Force. An organization responsible for
providing engineering solutions for TCP/IP networks. In the network
management area, this group is responsible for the development of the
SNMP protocol.

IGMP snooping

A mechanism performed by an intermediate device, such as a Layer 2
Switch, that optimizes the flow of multicast traffic. The device listens
for IGMP messages and build mapping tables and associated
forwarding filters, in addition to reducing the IGMP protocol traffic.
Interior Gateway
IGPs are protocols used in TCP/IP networks to exchange routing
Protocol (IGP)
information between collaborating routers.
Internet Group
Internet Group Management Protocol (IGMP) is a protocol that runs
Management
between hosts and their immediate neighboring multicast routers. The
Protocol
protocol allows a host to inform its local router that it wishes to receive
transmissions addressed to a specific multicast group. Based on group
membership information learned from the IGMP, a router is able to
determine which if any multicast traffic needs to be forwarded to each
of its subnetworks.
Intranet
An Intranet is an organization wide network using Internet protocols
such as web services, TCP/IP, HTTP and HTML. An Intranet is normally
used for internal communication and information, and is not accessible
to computers on the wider Internet.
IP
Internet Protocol. IP is a layer 3 network protocol that is the standard
for sending data through a network. IP is part of the TCP/IP set of
protocols that describe the routing of packets to addressed devices.
IPX
Internetwork Packet Exchange. IPX is a layer 3 and 4 network protocol
®
®
designed for networks that use Novell
Netware
.
IP address
Internet Protocol address. A unique identifier for a device attached to a
network using TCP/IP. The address is written as four octets separated
with periods (full-stops), and is made up of a network section, an
optional subnet section and a host section.
Jitter
An expression often used to describe the end-to-end delay variations
during the course of a transmission. See also latency.
