Chapter 39 GLOSSARY

Bandwidth Utilization
The percentage of packets received over time as compared to overall bandwidth.
BOOTP
Boot protocol used to load the operating system for devices connected to the network.
Distance Vector Multicast Routing Protocol (DVMRP)
A distance-vector-style routing protocol used for routing multicast datagrams through the Internet. DVMRP
combines many of the features of RIP with Reverse Path Broadcasting (RPB).
GARP VLAN Registration Protocol (GVRP)
Defines a way for switches to exchange VLAN information in order to register necessary VLAN members on
ports along the Spanning Tree so that VLANs defined in each switch can work automatically over a Spanning
Tree network.
Generic Attribute Registration Protocol (GARP)
GARP is a protocol that can be used by endstations and switches to register and propagate multicast group
membership information in a switched environment such that multicast data frames are propagated only to
those parts of a switched LAN containing registered endstations. Formerly called Group Address Registration
Protocol.
Group Attribute Registration Protocol
See Generic Attribute Registration Protocol.
Generic Multicast Registration Protocol (GMRP)
GMRP allows network devices to register end-stations with multicast groups. GMRP requires that any
participating network devices or end-stations comply with the IEEE 802.1p standard.
ICMP Router Discovery
ICMP Router Discovery message is an alternative router discovery method that uses a pair of ICMP
messages on multicast links. It eliminates the need to manually configure router addresses and is
independent of any specific routing protocol.
Internet Control Message Protocol (ICMP)
Commonly used to send echo messages (i.e., Ping) for monitoring purposes.
