Lossy
Trait of a network likely to lose data when it becomes heavily loaded.
MAC Address
Address of a port or computer that other devices use to locate those ports or computers.
These addresses are also used to create and update routing tables.
Management Information Base (MIB)
Network management information stored in a database. SNMP uses and maintains this
information.
mtrace
Command that tracks the multicast path from a source to a receiver.
Multi-Access Network
Network to which multiple routers are attached.
Multicast Group
Set of IP hosts that listen to an IP multicast address. It is possible for members of the group
to be spread across separate physical networks.
In IP multicasting, data is sent to this single IP address rather than being sent to each
host's individual IP address. These addresses are in the range of 224.0.0.0 to
239.255.255.255.
Multicast Packets
Individual packets sent to a network address that represents a single multicast group.
Multicast Routing
Method of routing in which individual packets are sent to many destinations.
In IP multicast routing, data is sent from one or more routers to a multicast group. The
data originates as a single packet destined to a multicast group. This differs from unicast
routing in which a router sends multiple unicast packets so that there is one packet for
each destination.
Neighboring Routers
Two routers that have interfaces to a common network.
NetWare
Network operating system developed by Novell that provides various network services,
such as transparent remote file access.
Network Interface Card (NIC)
Adapter that provides a computer's networking capability.
