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.
