Network Printing 2-9Unicast, Multicast, and BroadcastSLP is a unicast and a multicast protocol. This means that messages can besent to one agent at a time (unicast) or to all agents (that are listening) at thesame time (multicast). However, a multicast is not a broadcast. In theory,broadcast messages are “heard” by every node on the network. Multicastdiffers from broadcast because multicast messages are only “heard” by thenodes on the network that have “joined the multicast group.”For obvious reasons network routers filter almost all broadcast traffic. Thismeans 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 therouter’s perspective, a subnet is all machines connected to one of its ports).Multicasts, on the other hand, are forwarded by routers. Multicast traffic froma given group is forwarded by routers to all subnets that have at least onemachine that is interested in receiving the multicast for that group.SMBSMB (Server Message Block) is a protocol for sharing network resources,such as files and printers, in a Windows environment. If the Samba serversoftware is used on Linux or UNIX, services using SMB can be shared.SMTPSMTP (Simple Mail Transfer Protocol) is a protocol for sending E-mail.This protocol was originally used to send E-mail between servers; however,currently it is also used by client E-mail software that uses POP to sendE-mail to servers.SMTP AuthenticationSpecification that adds user authentication functions to SMTP, which is usedfor sending E-mail.When sending E-mail, authentication of the user is performed by the SMTPserver, and the E-mail message is permitted to be sent only if authenticationwas successful.SNMPSNMP (Simple Network Management Protocol) is actually a set of protocolsfor managing complex networks. SNMP works by sending messages to differ-ent parts of a network. SNMP-compliant devices, called agents, store dataabout themselves in Management Information Bases (MIBs) and return thisdata to the SNMP requesters.
