Network Printing 93
differs from broadcast because multicast messages are only “heard” by the
nodes on the network that have “joined the multicast group.”
For obvious reasons network routers filter almost all broadcast traffic. This
means that broadcasts that are generated on one subnet will not be “routed”
or forwarded to any of the other subnets connected to the router (from the
router’s perspective, a subnet is all machines connected to one of its ports).
Multicasts, on the other hand, are forwarded by routers. Multicast traffic from
a given group is forwarded by routers to all subnets that have at least one
machine that is interested in receiving the multicast for that group.
SMB
SMB (Server Message Block) is a protocol for sharing resources on the net-
work, such as files and printers, in a Windows environment.
If the Samba server software is used on Linux or UNIX, services using SMB
can be shared.
SNMP
SNMP (Simple Network Management Protocol) is actually a set of protocols
for managing complex networks. SNMP works by sending messages to differ-
ent parts of a network. SNMP-compliant devices, called agents, store data
about themselves in Management Information Bases (MIBs) and return this
data to the SNMP requesters.
TCP/IP
Most networks combine TCP (Transmission Control Protocol) with the
lower-level protocol IP (Internet Protocol). TCP establishes a virtual connec-
tion between two host systems and guarantees the delivery of data between
them while IP specifies the format and addressing of this data sent between
these two host systems.
