Glossary
Glossary-15
host
A single, addressable device on a network. Computers, networked printers, and routers
are hosts.
hunt group
A group of multiple telephone circuits that allows telephone calls to find an idle circuit to
establish a link.
I
IBGP
Interior BGP. The BGP used between peers in the same autonomous system, or, when
confederations are in use, between peers in the same confederation member autonomous
system (CMAS). All IBGP peers must maintain direct BGP connections to—be fully
meshed with—every other internal peer, but need not be physically attached to one
another.
ICMP
Internet Control Message Protocol. The part of the Internet Protocol (IP) that allows for
generation of error messages, test packets, and informational messages related to IP. This
protocol is used by the ping function to send an ICMP Echo Request to a network host,
which replies with an ICMP Echo Reply.
in-band signaling
Signaling over the data path.
injection policy
A set of rules that determine the path and route information the PortMaster takes from
BGP and places into its routing table used to forward packets to their destinations. The
PortMaster uses the information to determine how packets it receives are forwarded to
their ultimate destinations. See also policy.
interface
Connection and interaction between hardware, software, and the user. The interface
between components in a network is called a protocol. On the PortMaster, the virtual
connection between a PortMaster port and the network to which it is connected is called
an interface. The connection can be permanent as with the Ethernet interface or network
hardwired ports, or it can be temporary, as with ports used for dial-in or dial-out
connections.
